321STANLESS STEEL COIL| East King
INTRODUCTION
Stainless steel 321 is a Ni Cr Mo heat-resistant, titanium stable austenitic alloy, which is usually used in the temperature range of 1000 ° to 1600 ° F. 321 stainless steel is mainly used for continuous and intermittent service temperature applications with carbide precipitation range from 800 ° f to 1500 ° F. Type 321 is similar to type 304 stainless steel, but the addition of titanium is at least five times that of carbon. This addition of titanium reduces or prevents carbide precipitation during welding and service conditions from 800 ° to 1500 ° F. In order to provide the best resistance to intergranular corrosion and stress corrosion cracking of polysulfate at service temperatures from 1500 ° to 1650 ° F, air cooling can be used.
CHEMICAL COMPOSITION
| Element | Content (%) |
| Carbon (C) | 0.08 |
| Silicon (Si) | 1.00 |
| Manganese (Mn) | 2.00 |
| Phosphorus (P) | 0.045 |
| Sulfur (S) | 0.030 |
| Nickel (Ni) | 9.00-12.00 |
| Chromium (Cr) | 17.00-19.00 |
| Titanium (Ti) | 5C-0.70 |
EQUIVALENT GRADES
Germany: X10CrNiTi189
Domestic Brand: 0Cr18Ni10Ti
CHARACTERISTICS
Similar performance to 304 stainless steel.
Titanium addition enhances grain boundary corrosion resistance and high-temperature strength.
Effectively controls chromium carbide formation.
CORROSION RESISTANCE
Good resistance in atmospheric conditions.
Commonly used in petrochemical, power, bridge, and automotive industries.
Corrosion can occur under specific conditions; factors include medium concentration, pH, and temperature.
Long-term use at sensitization temperatures (450–850°C) can lead to intergranular corrosion due to chromium carbide precipitation at grain boundaries, reducing local chromium content.
INDUSTRY APPLICATION
It is used in outdoor machines with high chemical, coal and petroleum industries to resist grain boundary corrosion
1. Petroleum exhaust combustion pipeline
2. Engine exhaust pipe
3.Boiler shell, heat exchanger, heater parts
4. Silencing components for diesel engines
5.Boiler pressure vessel
6. Chemical tanker
7.Expansion joint
8. Spiral welded pipes for furnace pipes and dryers
Our company and China tisco, China Foshan steel, signed a perennial agent relationship. Large inventory, fast delivery, exquisite packaging, perfect products, high quality 321 stainless steel coil, the price has a huge advantage. Looking forward to cooperating with you.
