Super Austenitic Stainless Steel Pipe/Tube

Super austenitic stainless steel is defined as Cr-Ni stainless steel with a Pitting Resistance Equivalent Number (PREN=[Cr]+3.3[Mo]+16[N])≥40%. Super austenitic stainless steel is mainly developed to solve the deficiency of pitting corrosion resistance, crack corrosion resistance and poor thermal stability of the original high molybdenum (>4%) Cr-Ni austenitic stainless steel under the harsh corrosion conditions containing Cl-.
