introduction:Austenitic stainless steel has good corrosion resistance,Resistance to high temperature oxidation,Good low temperature performance and excellent mechanical and processing properties。Therefore, it is widely used in chemical industry、petroleum、power、Nuclear engineering、aerospace、ocean、medicine、Light industry、Textile and other sectors。Its main purpose is to prevent corrosion and rust。Corrosion resistance of stainless steel mainly depends on surface passivation film,If the membrane is incomplete or defective,Stainless steel can still be corroded。Pickling passivation is usually carried out in engineering,Make the corrosion resistance potential of stainless steel play more。In stainless steel equipment with parts in shape、assemble、weld、Weld inspection (Like flaw detection、Withstand voltage test)And construction marks
