Bright Stainless Steel Rod 304L 316L 316 321 310S 904L Stainless Steel Round Bar

We supply 321 stainless steel bars in various lengths and widths, and can be custom cut to your specific specifications. Our stainless steel coils can also be cut to the width you want. We are also a supplier of hexagonal bars and 321 round bars. Feel free to contact us to place an order.

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

Chemical composition

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): 5×C - 0.70%

Performance characteristics

Good corrosion resistance: in organic acids and inorganic acids of different concentrations and temperatures, especially in oxidizing media, it has good wear resistance and can be used to manufacture wear-resistant acid containers and wear-resistant equipment linings and conveying pipelines.

Good high temperature performance: Ti in 321 stainless steel bar exists as a stabilizing element. At the same time, it is a heat-resistant steel grade, which is much better than 316L in terms of high temperature, and has excellent high temperature stress rupture performance and high temperature anti-creep performance.

Controlling the formation of chromium carbide: Due to the addition of titanium, the formation of chromium carbide can be effectively controlled, making it more resistant to intergranular corrosion

Application areas

Aerospace: such as high-strength parts such as engine parts, aircraft rudders, and aircraft chassis.

Petrochemical: Corrosion-resistant parts such as pipes, valves, and pump bodies.

Automotive accessories: Parts in high-temperature and corrosive environments such as engine systems and exhaust systems.
