Product Description
321 stainless steel seamless pipe is an austenitic chromium-nickel stainless steel, with the domestic grade 1Cr18Ni9Ti and the US standard ASTM A312/TP321. It contains titanium (Ti) to enhance the resistance to intergranular corrosion.
The long-term use temperature of 321 stainless steel cold-drawn pipe is ≤800℃, and the short-term temperature can reach 900℃, which is better than 304 stainless steel. Especially in the temperature range of more than 450°C to 800°C, it can significantly reduce or avoid the occurrence of intergranular corrosion. It is suitable for petrochemical, aerospace, food processing and medical equipment.
