Description

321 stainless steel seamless pipe is a common austenitic 18/8 stainless steel alloy with titanium added, making it ideal for high temperature environments up to 900 ° C. It has good welding and forming capabilities and is widely used. Operating temperature environment exceeding 500 °C.

Advantage

It can destroy the cast structure of the ingot, refine the grain of the steel, and eliminate the defects of the microstructure, so that the steel structure is compacted and the mechanical properties are improved. This improvement is mainly reflected in the rolling direction, Hangzhou 321 stainless steel seamless pipe so that the steel is no longer isotropic to a certain extent; bubbles, cracks and looseness formed during pouring can also be used in high temperature and pressure Under welding.
