Duplex Seamless Stainless Steel Pipe

Duplex stainless steel pipe has good welding performance, compared with ferritic stainless steel and austenitic stainless steel, it is not like the welding heat affected zone of ferritic stainless steel, due to the serious grain coarsening and the plastic toughness is greatly reduced, it is not like austenitic stainless steel, more sensitive to welding heat crack.
