The yield strength of Q235B angle steel is 235MPa. Although the yield strength is low, its ductility and plasticity are excellent. It can withstand large deformation during processing without cracking. It is suitable for various cold and hot processing, such as bending, punching, etc.
S235 is a common structural steel in the European standard EN10025. Its strength is about two-thirds of that of ordinary carbon steel and its density is about 7.85 g/cm3. It has moderate strength and toughness and can maintain good performance stability in a variety of environments. It is suitable for some scenes that do not require particularly high strength but require certain structural support.
These angle irons comply with various standards such as ASTM, API, CE, BIS, tisi, JIS, GS, ISO9001, etc., which means that they have certain specifications and guarantees in terms of quality and production process, and can meet the quality requirements of different customers and different industries.
Q235B is a carbon structural steel under the Chinese GB/T700 standard. It has a low carbon content, which makes it have good plasticity and welding performance. Its yield strength is 235MPa, tensile strength is 370-500MPa, and elongation is high, which can meet certain plastic deformation requirements.
As structural steel, SS400/SS490/SS540 follows certain standard specifications, such as SS400 complies with JIS G 3101 standard, which ensures the stability and reliability of product quality and can meet the requirements of different projects for steel performance.
It has excellent strength, toughness and wear resistance, high hardenability, no temper brittleness, good weldability, little tendency to form cold cracks, good machinability and cold strain plasticity. Tensile strength σb (MPa) ≥ 885 (90), elongation δ5 (%) ≥ 12, cross-sectional shrinkage ψ (%) ≥ 50, impact energy Akv (J) ≥ 35, impact toughness value αkv (J/cm²) ≥ 98 (10), hardness ≤ 212HB
