Mar 17, 2020 · Q345 steel, with charicteristics of 7.85 g/cm3 material density, and 470-630 Mpa tensile strength, is a Chinese GB standard low alloy high strength structural steel. Q is the first letter of Chinese Pinyin:qu fu dian, which means Yield Point, 345 is the minimum value of yield strength for steel thickness less than 16mm. It is commonly used material among low alloy materials
Brief introduction of low alloy high strength steel 16Mn Sep 28, 2018 · As a old Chinese standards, 16Mn is edited from GB 1591-1988 "low alloy structural steel", has now been replaced by Q345. Low alloy steel Q345 steel has 5 quality grades, which are represented by from Q345A to Q345E. It can be said that Q345 steel is the substitution of old brand steel of 12MnV, 14MnNb, 18Nb, 16MnRE, 16Mn and other steel types

Mechanical properties of Q345 structural steel after Jan 01, 2021 · The Q345 steel that was used to fabricate the tensile test specimens was manufactured in China; its chemical composition is tabulated in Table 1. In Chinese, Q represents the yield strength and 345 indicates that the minimum nominal yield strength is 345 MPa.
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.
