Prime Quality 321 Stainless Steel Plate

321 stainless steel plate is used in field open-air machines for chemical, coal and petroleum industries with high resistance to intergranular corrosion, heat-resistant parts for building materials and parts with difficult heat treatment.

Prime Quality 321 Stainless Steel Plate


Chemical Composition


Sulfur: 0.030

Nickel: 9.00-1.20

Chromium: 17.00-19.00

Titanium: 5C-0.70

Austenitic stainless steel is equivalent to domestic 1Cr18Ni9Ti

US brands are: 321, S32100, TP321

Japanese brand: SUS321

British brand: 304S12, 321920

German brand: X10CrNiTi189


Among the 321 stainless steel plates, Ti exists as a stabilizing element, but it is also a heat-strength steel, which is much better than the 316L stainless steel plate in high temperature. The 321 stainless steel plate is especially suitable for organic acids and inorganic acids at different concentrations and temperatures. It has good abrasion resistance in oxidizing medium, and is used for manufacturing lining and conveying pipeline of wear-resistant acid container and wear-resistant equipment.


The 321 stainless steel plate is a Ni-Cr-Mo austenitic stainless steel plate, and its performance is very similar to that of the 304 stainless steel plate, but it has better resistance to intergranular corrosion and high temperature strength due to the addition of titanium metal. Due to the addition of titanium metal, it effectively controls the formation of chromium carbide.


The 321 stainless steel plate has excellent high temperature stress breaking (Stress Rupture) performance and high temperature creep resistance stress mechanical properties superior to 304 stainless steel plates.


The difference


The difference between 321 stainless steel plate and other stainless steel plates

321 containing titanium

316 with molybdenum

304 contains neither titanium nor molybdenum

Mo2Ti contains both molybdenum and titanium. Performance 316L is optimal, 321/304 is generally.


Industry application


1. Petroleum waste gas combustion pipeline

2. Engine exhaust pipe

3. Boiler casing, heat exchanger, furnace components

4. Dust-proof parts for diesel engines

5. Boiler pressure vessel

6. Chemical transport vehicles

7. Expansion joint

8. Spiral welded pipe for furnace pipe and dryer

The formula of 321 stainless steel plate: thickness (mm) X width (m) X length (m) X density
