Stainless Steel Strip

Introduction:

The stainless steel Strip is simply an extension of an ultra-thin stainless steel plate. It is mainly a narrow and long steel plate produced to meet the needs of different industrial sectors for the industrial production of various types of metal or mechanical products.

Classification:

There are many types of stainless steel belts, with wide applications: 201 stainless steel belt, 202 stainless steel belt, 304 stainless steel belt, 301 stainless steel belt, 302 stainless steel belt, 303 stainless steel belt, 316 stainless steel belt, J4 stainless steel belt, 309S stainless steel belt, 316L stainless steel belt, 317L stainless steel belt, 310S stainless steel belt, 430 stainless steel iron belt, etc.! Thickness: 0.02mm-4mm, width: 3.5mm-1550mm, can be made without calibration!

Stainless steel with domestic (imported) stainless steel belt: stainless steel coil belt, stainless steel spring belt, stainless steel stamping belt, stainless steel precision belt, stainless steel mirror belt, stainless steel cold-rolled belt, stainless steel hot-rolled belt, stainless steel etching belt, stainless steel stretch belt, stainless steel Polishing belt, stainless steel soft belt, stainless steel hard belt, stainless steel medium hard belt, stainless steel high temperature resistant belt, etc.

Cold rolled strip

① Using “stainless steel strip/coil” as raw material, it is rolled into a material by cold rolling machine at normal temperature. Conventional thickness <0.1mm~3mm>, width <100mm~2000mm>;

②["Cold rolled steel strip/coil"] has the advantages of smooth surface, smooth, high dimensional accuracy and good mechanical properties. Most of the products are in coils and can be processed into coated steel plates;

③ Cold-rolled stainless steel strip/coil production process: ⒈ pickling → ⒉ normal temperature rolling → ⒊ process lubrication → ⒋ annealing → ⒌ flattening → ⒍ precision cutting → ⒎ packaging → ⒏ to reach the customer.

Hot rolled strip

①Strip steel with thickness of 1.80mm-6.00mm and width of 50mm-1200mm is made by hot rolling machine.

②[Hot rolled strip/sheet] has the advantages of low hardness, easy processing and good ductility.

③ Production process of hot-rolled stainless steel strip/coil: ⒈ pickling → ⒉ high-temperature rolling → ⒊ process lubrication → ⒋ annealing → ⒌ flattening → ⒍ precision cutting → ⒎ packaging → ⒏ to reach the customer.

The difference between hot and cold

①Cold-rolled steel strip has good strength and yield ratio, and hot-rolled steel strip has good ductility and toughness.

②The surface quality, appearance and dimensional accuracy of cold-rolled steel strips are better than hot-rolled sheets.

③The thickness of cold-rolled steel strip is ultra-thin, and the thickness of hot-rolled steel is large.

Silicon steel thin strip

The grain-oriented silicon steel thin strip is also called cold-rolled silicon steel strip for telecommunications industry. It is used to manufacture various power transformers, pulse transformers, magnetic amplifiers, converters and other iron cores with operating frequencies above 400 Hz. Silicon steel thin strips larger than 0.20mm.

Cold rolled steel strip

Cold-rolled steel strip for deep drawing is a low-carbon high-quality carbon structural steel cold-rolled steel strip for deep drawing of complex drawn parts.

delivery status:

Delivery after heat treatment and smoothing.

The surface of the steel strip supply state should be rough or shiny.

Usage: widely used in automobiles, tractors and other industries.

performance:

Stainless steel belts, like other materials, mainly include the following three physical properties: melting point, specific heat capacity, thermal conductivity and linear expansion coefficient and other thermodynamic properties, electrical resistivity, electrical conductivity and magnetic permeability and other electromagnetic properties, and Young's modulus of elasticity , Rigidity and other mechanical properties. These properties are generally considered to be the inherent characteristics of stainless steel materials, but are also affected by factors such as temperature, degree of processing, and magnetic field strength. Normally, stainless steel has lower thermal conductivity and higher resistance than pure iron, while properties such as linear expansion coefficient and magnetic permeability vary depending on the crystal structure of stainless steel itself.

Table 4-1 to Table 4-5 list the physical properties of martensitic stainless steel, ferritic stainless steel, austenitic stainless steel, precipitation hardening stainless steel and duplex stainless steel. Parameters such as density, melting point, specific heat capacity, thermal conductivity, linear expansion coefficient, resistivity, magnetic permeability, and longitudinal elasticity coefficient.

Correlation between physical properties and temperature

(1) Specific heat capacity

As the temperature changes, the specific heat capacity will change, but once the phase change or precipitation occurs in the metal structure during the temperature change, the specific heat capacity will change significantly.

(2) Thermal conductivity

Below 600℃, the thermal conductivity of various stainless steels is basically in the range of 10~30W/(m·℃). With the increase of temperature, the thermal conductivity increases. At 100 ℃, the thermal conductivity of stainless steel in the order of large to small is 1Cr17, 00Cr12, 2 Cr 25N, 0 Cr 18Ni11Ti, 0 Cr 18 Ni 9, 0 Cr 17 Ni 12Mο2, 2 Cr 25Ni20. The thermal conductivity at 500 ℃ The smallest order is 1 Cr 13, 1 Cr 17, 2 Cr 25N, 0 Cr 17Ni12Mο2, 0 Cr 18Ni9Ti and 2 Cr 25Ni20. The thermal conductivity of austenitic stainless steel is slightly lower than other stainless steels. Compared with ordinary carbon steel, the thermal conductivity of austenitic stainless steel is about 1/4 of that at 100℃.

(3) Coefficient of linear expansion

In the range of 100-900℃, the linear expansion coefficients of various types of stainless steel are basically in the range of 10ˉ6~130*10ˉ6℃ˉ1, and they increase with increasing temperature. For precipitation hardening stainless steels, the linear expansion coefficient is determined by the aging treatment temperature.

(4) Resistivity

At 0~900℃, the specific resistance of various types of stainless steel is basically 70*10ˉ6~130*10ˉ6Ω·m, and it tends to increase with the increase of temperature. When used as a heating material, a material with low resistivity should be used.

(5) Magnetic permeability

The magnetic permeability of austenitic stainless steel is extremely small, so it is also called non-magnetic material. Steel with a stable austenite structure, such as 0 Cr 20 Ni 10, 0 Cr 25 Ni 20, etc., will not be magnetic even if it is processed with a large deformation of more than 80%. In addition, high-carbon, high-nitrogen, high-manganese austenitic stainless steel, such as 1Cr17Mn6NiSN, 1Cr18Mn8Ni5N series and high-manganese austenitic stainless steel, etc., will undergo ε phase transformation under large reduction processing conditions, so they remain non-magnetic. At high temperatures above the Curie point, even strong magnetic materials lose their magnetism. However, some austenitic stainless steels, such as 1Cr17Ni7 and 0Cr18Ni9, have a martensitic transformation during cold working at high reduction or low temperature because of their metastable austenite structure. Conductivity will also increase.

(6) Elastic modulus

At room temperature, the longitudinal elastic modulus of ferritic stainless steel is 200 kN/mm2, and the longitudinal elastic modulus of austenitic stainless steel is 193 kN/mm2, which is slightly lower than that of carbon structural steel. As the temperature increases, the longitudinal elastic modulus decreases, the Poisson's ratio increases, and the lateral elastic modulus (rigidity) decreases significantly. The longitudinal elastic modulus will have an effect on work hardening and tissue assembly.

(7) Density

The ferrite stainless steel with high chromium content has a small density, and the austenitic stainless steel with high nickel content and high manganese content has a high density. At high temperatures, the density becomes smaller due to the increase in the character spacing.

Physical properties at low temperature

(1) Thermal conductivity

The thermal conductivity of various types of stainless steel at very low temperatures is slightly different, but in general it is about 1/50 of the thermal conductivity at room temperature. At low temperatures, the thermal conductivity increases with increasing magnetic flux (flux density).

(2) Specific heat capacity

At very low temperatures, there are some differences in the specific heat capacities of various stainless steels. The specific heat capacity is greatly affected by temperature, and the specific heat capacity at 4k can be reduced to less than 1/100 of the specific heat capacity at room temperature.

(3) Thermal expansion

For austenitic stainless steel, the shrinkage rate (relative to 273K) is slightly different under 80k. Nickel content has a certain effect on shrinkage.

(4) Resistivity

At very low temperatures, the difference in resistivity between brands increases. Alloying elements have a greater influence on the resistivity.

(5) Magnetic

At low temperatures, austenitic stainless steels have different effects on the load magnetic field depending on their mass susceptibility. The content of different alloy elements is also different.

There is no difference in the permeability of different brands.

(6) Elastic modulus

At low temperatures, the Poisson's ratio of austenite stainless steels with magnetic transformations produces corresponding extreme values.
