Q235 carbon structural steel application Q235 section steel

Q235 ordinary carbon structural steel material of a steel. Q represents the yielding limit of this material, the latter 235, is the yield value of this material, in 235MPa or so. And will increase with the thickness of the material to reduce the yield value, as Q235 carbon moderate, better overall performance, strength, plasticity and welding performance is better with the most widely used.

Q235 Chemical composition：
Q235 points A, B, C, D four grades (GB / T 700-2006)
Q235A containing C ≤ 0.22%  Mn 0.3% -0.65%  Si ≤ 0.35%  S ≤ 0.050  P ≤ 0.045
Q235B containing C ≤ 0.20%  Mn 0.3% -0.7%  Si ≤ 0.35%  S ≤ 0.045  P ≤ 0.045
Q235C containing C ≤ 0.17%  Mn 0.35% -0.8%  Si ≤0.35%  S ≤ 0.040  P ≤ 0.040
Q235D containing C ≤ 0.17%  Mn 0.35% -0.8%  Si ≤ 0.35%  S ≤ 0.035  P ≤ 0.035

Q235Mechanical behavior：
Density: 7.85 g / cm & lt; 3 & gt ;.
Elastic modulus (E / Gpa): 200-210
Poisson's ratio (ν): 0.25 to 0.33
Tensile strength (σb / MPa): 375-460
Elongation (δ5 /%):
≥26 (a≤16mm)
≥25 (a> 16-40mm)
≥24 (a> 40-60mm)
≥23 (a> 60-100mm)
≥22 (a> 100-150mm)
≥21 (a> 150mm)
Where a is the thickness or diameter of the steel.

Q235 Species and uses：
Q235 usually rolled from: wire rod or bar, square steel, flat steel, angle steel, I-beam, channel steel and other steel, medium and thick steel plate. Size can be customized according to customer needs.
1, Q235 is widely used in construction and engineering structures. High-voltage transmission tower, bridges, vehicles, boilers, containers, ships, etc., but also a lot for the performance requirements are not too high mechanical parts. Q235 C, D grade steel can also be used for some professional use of steel.
2, Q235 can be used for a variety of mold handles and other unimportant mold parts.
3, the use of Q235 steel punch material, the quenching is not directly after the use of tempering, hardness 36 ~ 40HRC, to solve the punch in the use of the phenomenon of fragmentation.
