Grades：N08366,N08367,N08904（904L）, N08925,N08926,S31254
Specifications：
ASME SA213 Specification for Seamless Ferritic and Austenitic Alloy-Steel Boiler, Superheater, and Heat-Exchanger Tubes
ASME SA312 Specification for Seamless, Welded, and Heavily Cold Worked Austenitic Stainless Steel Pipes
ASTM A269 Specification for Seamless and Welded Austenitic Stainless Steel Tubing for General Service
ASME SB677 Specification for UNS N08904, UNS N08925, and UNS N08926 Seamless Pipe and Tube
ASME SB690 Specification for Iron-Nickel-Chromium-Molybdenum Alloys (UNS N08366 and UNS N08367) Seamless Pipe and Tube
Features：
1.Superior resistance to chloride pitting, crevice corrosion in aggressive environment
2.Good mechanical properties with high yield strength
3.Excellent machinability
When the pitting corrosion resistance equivalent value of Cr-Ni austenitic stainless steel is greater than or equal to 40%, it can be called super austenitic stainless steel. Super austenitic stainless steel is mainly developed to solve the defects of pitting corrosion resistance, crevice corrosion resistance and poor thermal stability of the original high molybdenum (more than 4%) Cr-Ni austenitic stainless steel under severe corrosion conditions containing chloride ions.
