Product Name: SA 312 Tp904L Tube Model NO.: DN 50 (NPS 2) SCH. 80S Connection Type: Seamless Cross-Section Shape: Round Medium: According to Reqirement Diameter: 19.05mm Standard: ASTM, GB, API, DIN, JIS Material: Alloy Steel MPa Classfication: Medium Pressure Piping Temperature Classification: Cold Drawn Trademark: Paideer Transport Package: Plywood Box Specification: 60.3*5.54mm Origin: China HS Code: 7304419000 Product Description Super austenitic stainless steelWhen the pitt-resistance of chrome-nickel austenitic stainless steel (PREN=[Cr]+3.3[Mo]+16[N]) is greater than 40%, it can be called super austenitic stainless steel. The super-austenitic stainless steel is mainly developed for the solution of the deficiency of the original high molybdenum (>. 4%) chrome-nickel austenitic stainless steel, such as pitting corrosion resistance, crevice corrosion resistance and tissue thermal stability under the harsh corrosion conditions of Cl- containing corrosion.Major brands: N08904 (904L), N08367 (6Mo), S31254 (6Mo), S30432, S31042Main standards (part) :ASTM A312 seamless and welded austenitic stainless steel tubeASTM A269 general equipment USES seamless and welded austenitic stainless steel tubesASTM B673,ASTM B674,ASTM B677,ASTM B675,ASTM B676, ASTM B690Performance features:1. Excellent resistance to pitting and crevice corrosion in harsh corrosion environment2. Excellent mechanical properties and high yield strength3. Good machinability
