ASTM A36 steel equivalent grade steel plate,ASTM A36 steel

ASTM A36 steel is very popular in the construction field.Q235B,A283C,S235JR,ST37-2,SS400 steel grades are ASTM A36 steel equivalent grades..To be ASTM A36 steel equivalent grade,the steel material should have similar chemical composition and mechanical properties to ASTM A36 steel.COR-TEN,CORTEN A,CORTEN STEEL,A242,A558 GRCOR-TEN A 355 470-630 20 *) 1 Mpa = 1N/mm2 In case of cold rolled material the yield point is min.310 Mpa and the tensile strength min.445 MPa.Furthermore cold rolled sheets 3mm in thickness made of steel grade COR-TEN A-F for increased demand to the cold formability is available.Mechanical properties Yield point min.275Cor-Ten steel plate-weathering resistant steel platesCorten steel plate has successfully overcome rust,steels most weakest.When exposed to the atmosphere without painting,corten steel begins to rust in the same way as ordinary steel.BUT soon the alloying elements in COR-TEN cause a protective surface layer of the fine-textured rust to form,thereby suppressing corrosion rate.
