Detailed Product Description

Stainless Steel Seamless Pipe And Tubes 1.4541 TP321 TP321H F321 12X18H10T, Low temperature application

Stainless Steel 321 is a basic austenitic 18/8 steel (Grade 304) stabilised by Titanium (321) addition. SS 321 is used because they are not sensitive to intergranular corrosion after heating within the carbide precipitation range of 425-850°C. SS 321 is the grade of choice for applications in the temperature range of up to about 900°C, combining high strength, resistance to scaling and phase stability with resistance to subsequent aqueous corrosion. SS 321H is a modification of SS 321 with a higher carbon content, to provide improved high temperature strength.
