It got great weldability and machinability, let us see more mechanical details of this steel.
Q345B steel is a Chinese standardized low alloy, medium tensile strength steel made with a hot-rolling process, and is used for a number of manufacturing purposes. It is a steel with less than 0.2 percent of its composition made up of carbon, less than 0.55 percent of its composition made of silicon and several impurities (mostly sulfur, chromium and nickel). New China Standard-Q345B Changed to Q355BCompared with the European standard EN10025, it is known that not only the brand names are similar, but also the chemical composition and mechanical properties are similar. For example, the first element C, the old national standard B level is less than or equal to 0.20, and the same as the European standard JR level. 0.24, of course, this is New DocumentCold Rolled Steel Strip Quality:Q195, Q215, Q235 Chemical Composition & Mechanical Properties refer to the table:
Dec 12, 2019 · Some foreign customers are often confused about GB Q345 steel. Q345 low alloy high strength steel is the replacement steel of old GB grade 12MnV, 14MnNb, 18Nb, 16MnRE, 16Mn, etc. The chemical element is similar to 16Mn, and Q345 increases the micro alloy element V, Ti and Nb which refines the grain, greatly improving the toughness and comprehensive mechanical properties of steel, 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 < 0.050, Q235 has requirements for More element C, Si, Mn, S, P. Yield strength of q235 is >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. 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 < 0.050, Q235 has requirements for More element C, Si, Mn, S, P.
