Krygen Metalloys is also supremely pleased to present Stainless Steel 321H Pipes that are strong in ensuring perfect performance even in high temperature conditions. Being the manufacturers and exporters with rich experience, we can provide pipes which correspond to the high customer demands of the modern industry. Stainless Steel 321H is an austenitic stabilized stainless steel containing more carbon than that of the usual 321 stainless steel and as such finds particularly useful application at high temperature where creep resistance and stress rupture behavior are critical factors.
These pipes are also well-known to resist oxidation, thermal stability, and durability. Stainless Steel 321H Pipes are well-suited to long-lasting processes, even under high temperatures of up to 900 o C, because they are highly resistant against intergranular corrosion even after long exposure to high temperatures. Krygen Metalloys maximizes that all the pipes manufactured by us are manufactured under international standards such as ASTM A 312 and ASME SA 312 which makes them consistent, traceable and reliable in all the applications.
