What Are The Classification Of Stainless Steel Pipes

Proper postweld heat treatment can restore the phase equilibrium ratio and the content of chromium, molybdenum and other alloy elements in austenite γ And ferrite α The distribution between them can dissolve harmful precipitates. Therefore, it is of great significance to study the microstructure of welded joint of duplex stainless steel pipe and the post-weld heat treatment.
It can make the stainless steel pipe obtain better mechanical properties and welding properties. It can be used in the fields of petrochemical industry, low-temperature equipment, instruments and strong acid corrosive medium containers, etc.
