Our company supply low-alloy high-strength structural steel common grades below: Q345B / C / D / E, A572Grade 50 sheet, A572Gr.55 plate, BS700MC cold forming steel coil, A514 Grade B material, A709 Grade 50 steel. The company can provide low alloy structural steel plate thickness range of 6 ~ 200mm. Our low-alloy high-strength steel is widely used in various types of engineering structures such as steel structure construction, construction machinery, mining machinery, heavy vehicles, bridges, pressure vessels.

4140 steel is alloy structural steel, and its technical standard is ASTM A29/A29M. It belongs to ultra-high strength steel. BS700MC cold forming steel coil, 4140 steel has high strength and toughness, good hardenability, no obvious temper brittleness, high fatigue limit and multiple impact resistance after tempering treatment, and good low temperature impact toughness. 4140 steel is suitable for manufacturing large and medium plastic mould with certain strength and toughness.

Composition characteristics of low alloy structural steel, BS700MC cold forming steel coil: (1) Low carbon: the carbon content of low alloy structural steel is less than 0.20% due to the high requirements of toughness, weldability and cold formability. (2) The alloy elements such as manganese are added. (3) The addition of Nb, Ti or V and other auxiliary elements: a small amount of Nb, Ti or V forms fine carbides or carbonitrides in the steel, which is beneficial to obtain fine ferrite grains and improve the strength and toughness of low alloy structural steel. In addition, adding a small amount of copper (≤ 0.4%) and phosphorus (about 0.1%) can improve the corrosion resistance. The addition of a small amount of rare earth elements can remove sulfur and gas, purify the steel, and improve the toughness and process performance of low alloy structural steel.

JIS g3101:2004 ss540 structural steel angle contains 0.30% carbon and 1.60% manganese, which greatly improves the strength of steel. Compared with BS700MC cold forming steel coil SS400 and ss490, ss540 has higher strength with yield strength of 400MPa and tensile strength of 540Mpa. High strength makes it popular in applications that require strength but weight is a problem.
