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
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.

The following tables show Q235A, Q235B, Q235C and Q235D steel datasheet and specification, including chemical composition, physical and mechanical properties, etc. 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 Q345 angle steel Application,Q345 angle steel standard Q345 angle steel is a steel material. It is a low-alloy steel, widely used in bridges, vehicles, ships, buildings, pressure vessels, special equipment. "Q" means the yield strength, Q345 angle steel indicates that the steel yield strength of 345MPa. Q345 angle steel will increase the thickness of the material and its yield value decreases. And the possibility of a small domestic. High strength steel
The Q345 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. This particular grade of steel is a general purpose manufacturing steel in construction equipment field. Q345 steel property and specification are equivalent to The Q345 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.
