Q345 steel property and specification are equivalent to

Q345 steel is one kind of Chinese standardized low alloy,medium tensile strength steel made with a hot-rolling process,used for a number of manufacturing purposes.To some extent,the Q345 possesses the same property and composition of ASME A572,namely the Q345 is equivalent to A572.Q345 Steel Specification and Equivalent StandardQ345 steel specification Q345 steel belongs to 16Mn steel grade,usually it is produced in hot rolled state,hot rolled steel plate,hot rolled steel coil/sheet,it has comprehensive mechanical and welding property,as it shows good performance in structural purposes,it is widely used as welding structural part in manufacturing of ship,railway and vehicles,bridges,boiler,pressure vessel Overview of Q235 Steel Plate SpecificationQ235 steel is equivalent to Japenese steel grade SS400 in application,the only difference is that ss400 steel requires only S,P composition q345 c steel pdflt; 0.050,Q235 has requirements for More element C,Si,Mn,S,P.Yield strength of q235 is q345 c steel pdfgt;235Mpa,which is almost the same to SS400 245Mpa.Q represents the yield of this material,the latter 235,refers to the yield value of this material,at about 235MPA.
