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.
brace in the joint was steel Q345.The brace was connected to the chord through manual arc welding with full penetration weld in accordance with AWS 2000 .The chord was filled with concrete,while the brace was unfilled.Static tests in the elastic range were first conducted on the welded CFCHS TMicrostructure and Mechanical Properties of Frictiontemperatures for Q345 steel undergoing phase transition are Ac 1 = 756 q345 c steel pdf#176;C,and Ac 3 = 900 q345 c steel pdf#176;C.27) The HAZ was affected by heat conduction during welding the literature shows that the maximum temperature in this region was probably about 900 q345 c steel pdf#176;C.28,29) Phase transition occurred in part of the HAZ,ferrite and pearlite turn to austenite.Since theInvestigation of the Surface Integrity of Q345 Steel After As a common mechanical material for mining machinery,Q345 is prone to oxidation due to the moist working environment.At present,laser cleaning is often used to remove rust oxides from the substrate.The pollutant of mining machinery is comprised of a heavy oxide layer and organic ingredients,which are difficult to remove and require high energy per pulse.
