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 Q355B

Compared 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 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 steel chemical compositionlt; 0.050, Q235 has requirements for More element C, Si, Mn, S, P. Yield strength of q235 is q345 steel chemical compositiongt;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.

Q195 Steel Chemical Composition, Mechanical Properties The latest standard of Q195 steel is GB/T 700 2006, for chemical composition, mechanical properties and equivalent, please see the following tables. Q195 Material Features and Applications Q195 material has high plasticity, toughness and weldability, good pressure and processability, but low strength.

Q195 Steel Chemical Composition, Mechanical Property

Q195 steel is Chinese steel grade of carbon structural steel, Q stands for Yield Strength, 195 means the Yield Strength is 195 Mpa, and Tensile Strength is 315 430 Mpa, data is tested based on a 16mm diameter steel bar. Q195 material density is 7.85 g/cm3, the physical properties and chemical composition are equivalent to ASTM Gr.B(s185), Gr.C(s205); DIN St33, S185 Q235 Steel Plate Equivalent Steel Standard-ASTM A36Different chemical composition:The content of Mn element in A36 due to the plate thickness (or diameter) of different instead, below 20mm, without Mn.
