STAINLESS STEEL 904L CNC COMPONENTS : STAINLESS STEEL 904L CNC COMPONENTS AVAILABILITY :• Seamless Pipe 1/2" W STAINLESS STEEL 904L CNC COMPONENTS SPECIFICATION :• ASTM B677, B366• ASME SB677, SB366 STAINLESS STEEL 904L CNC COMPONENTS DESCRIPTION :904L is a high-alloy austenitic stainless steel with low carbon content. The grade is intended for use under severe corrosive conditions. It has been application proved over many years and was originally developed to resist corrosion in dilute sulfuric acid. It is standardized and approved for pressure vessel use in several countries. Structurally, 904L is fully austenitic and is less sensitive to precipitation ferrite and sigma phases than conventional austenitic grades with high molybdenum content. Characteristically, due to the combination of relatively high contents of chromium, nickel, molybdenum and copper 904L has good resistance to general corrosion, particularly in sulfuric and phosphoric conditions. STAINLESS STEEL 904L CNC COMPONENTS DESIGN FEATURES :• Good resistance to pitting and crevice corrosion.• Very good resistance to stress corrosion cracking.• Good resistance to intergranular corrosion.• Good formability and weldability.• Maximum service temperatures of 450 deg.C. (824 deg.F). STAINLESS STEEL 904L CNC COMPONENTS TYPICAL APPLICATIONS :• Production and transport of sulfuric acid• Metal pickling in sulfuric acid• Production and concentration of phosphoric acid• Use in seawater, brackish water, condensers, heat exchangers and pipe work in general• Paper and allied industries• Gas washing• Chemical and pharmaceutical industries STAINLESS STEEL 904L CNC COMPONENTS TENSILE REQUIREMENTS :• Tensile Strength (KSI) 70• Yield Strength (KSI) 25• KSI can be converted to MPA (Megapascals) by multiplying by 6.895.
