Product Name:Q235A, B, C, D Steel

Q235A, B, C, D Steel

Application

all kinds

Product Description:

Ordinary carbon steel, Q235 often called A3 round steel. Regularly used for the production of riveting.Q represents the yield of the material degree, number 235, refers to the value of this material. Material thickness increase impacted its yield value decrease.
For the moderate carbon, better overall performance, strength, ductility and welding, with good performance. Often rolled into wire rod or bar, square steel, flat steel, angle iron, beams, channels, window frames, steel beam, the thick steel plate.
Large number used in the construction and engineering structures. Or build a plant for the production of steel house frames, high-voltage transmission towers, bridges, vehicles, boilers, containers, ships, etc., but also a lot for the mechanical parts that do not have too high requirements on the performance.
A, B, C, D, are different, referring to the impact of their performance in different temperatures. Q235A level, is not to shock; Q235B grade, is 20 degrees room temperature impact; Q235C level, is 0 degree impact; Q235D level is -20 degrees impact.  
Low-alloy plate Q235 points A, B, C, D (GB700-88). Q235A-level with C 0.14 ~ 0.22%, Mn 0.30 ~ 0.65, Si 0.30, S 0.050, P 0.045; Q235B grade with C 0.12 ~ 0.20%, Mn 0.30 ~ 0.67, Si 0.30, S 0.045, P 0.045; Q235C-level with C 0.18%, Mn 0.35 ~ 0.80, Si 0.30, S 0.040, P 0.040; Q235D level with C 0.17%, Mn 0.35 ~ 0.80, Si 0.35, S 0.040, P 0.035.
Tensile strength of the mechanical properties of Q235 (b / MPa): 375-500 elongation (5 /%): 26 (a 16mm) 25 (a> 16-40mm) 24 (a> 40-60mm) 23 (a> 60-100mm) 22 (a> 100-150mm) 21 (a> 150mm). External standard: GB/T709-2006 "hot rolled steel sheet and strip size, shape, weight and tolerance", internal standard: GB/T3274-2007 "carbon structural steel and low alloy steel and heat thick steel plate and strip rolling"
