AISI 430 Stainless Steel Coil

430 Stainless Steel Coils | East King

430 stainless steel is a general-purpose steel with good corrosion resistance, thermal conductivity is better than austenite, thermal expansion coefficient is smaller than austenite, heat fatigue resistance, the addition of stabilizing element titanium, the mechanical properties of the welded part is good. 430 stainless steel is used for building decoration, fuel burner parts, household appliances, and home appliance parts. 430F is a steel grade with easy cutting performance added to 430 steel, which is mainly used for automatic lathes, bolts and nuts. 430LX adds Ti or Nb to 430 steel, reduces C content, improves processing performance and welding performance, and is mainly used for hot water tanks, hot water supply systems, sanitary appliances, household durable appliances, bicycle flywheels, etc.

Because of its chromium content, it is also called 18/0 or 18-0. Compared with 18/8 and 18/10, there is a little less chromium, and the hardness decreases accordingly.

CHEMICAL COMPOSITION

MECHANICAL PROPERTIES

SURFACE GRADE

430 stainless steel has the following states, the state is different, the dirt resistance and corrosion resistance are also different.

NO.1, 1D, 2D, 2B, N0.4, HL, BA, Mirror, and various other surface treatment states.

Feature processing

1D—The surface has discontinuous particles, also known as matte surface. Processing technology: hot rolling + annealing shot peening + cold rolling + annealing pickling.

2D—Slightly shiny silver white. Processing technology: hot rolling + annealing shot peening + cold rolling + annealing pickling.

2B—Silver white and better gloss and flatness than 2D surface. Processing technology: hot rolling + annealing shot peening + cold rolling + annealing pickling + temper rolling.

BA—Excellent surface gloss and high reflectivity, just like a mirror surface. Processing technology: hot rolling + annealing shot peening + cold rolling + annealing pickling + surface polishing + temper rolling.

No.3—It has good gloss and rough surface. Processing technology: Polishing and tempering rolling of 100-120 abrasive materials (JIS R6002) for 2D products or 2B.

No. 4—It has good gloss and fine lines on the surface. Processing technology: polish and temper the 2D products or 2B with 150-180 abrasive materials (JIS R6002).

HL—Silver gray with hairline stripes. Processing technology: Polish the 2D product or 2B product with an appropriate particle size to make the surface continuous.

MIRRO—in mirror state. Processing technology: 2D product or 2B product is ground and polished to a mirror effect with an appropriate particle size abrasive material.

MATERIAL PROPERTIES

430 stainless steel has the ability to resist oxidation to corrosion, but has a tendency to intergranular corrosion.

430 stainless steel wire is widely used in the shaft.

Because it is safe and non-toxic, it is widely used in food tableware.
