    ASTM A312 TP321 Stainless Steel Pipe Supplier

    Professional Manufacturer Of 200/300/400 Series Stainless Steel Pipe In India, Raajsagar Steels is one of the leader manufacturers, Supplier and exporters of high quality Stainless Steel 321 Pipes & Tubes, SS 321 pipes Mumbai India, Raajsagar Steels high strength as well as scaling resistance and phase stability set 321 Stainless Steel apart from other similar grades.


    Type 321 is a stabilized stainless steel which offers as its main advantage an excellent resistance to intergranular corrosion following exposure to temperatures in the chromium carbide precipitation range from 800 to 1500° F (427 to 816° C). Type 321 is stabilized against chromium carbide formation by the addition of titanium.

    While Type 321 continues to be employed for prolonged service in th4e 800 to 1500° F (427 to 816° C) temperature range, Type 304L has supplanted this stabilized grade for applications involving only welding or short time heating.

    Type 321 stainless steel s also advantageous for high temperature service because of its good mechanical properties. Type 321 stainless steel offers higher creep and stress rupture properties than Type 304 and, particularly, Type 304L which might also be considered for exposures where sensitization and intergranular corrosion are concerns. This results in higher elevated temperature allowable stresses for this stabilized alloy for ASME Boiler and pressure Vessel Code applications. The Type 321 alloy has a maximum use temperature of 1500°F (816° C) for code applications like Type 304, whereas Type 304L is limited to 800° F (426° C).
