GB/T700 Q235B steel plate supplier. Introduction and application of Q345 low alloy steel - EB Jul 22, 2019 · The lower limit of yield strength of Q235 is 235Mpa, and that of Q345 is 345Mpa (Q means qu in Chinese, and the following value represents the lower limit of yield strength). They have different gold content:Q235 is ordinary carbon steel, Q345 is low alloy steel. Mechanical properties of Q345:Mechanical properties of Q345D seamless pipe: Mechanical Properties of Chinese Low Alloy Steel Q345BMechanical Properties of Chinese low alloy steel:Q345B 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.
Q235 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.
