Our company has B750L structure steel for cold forming strong technical force, complete production equipment, advanced production technology, perfect testing methods, and high quality. It has a Class D (Class I and Class II pressure vessel) manufacturing license, and has passed the China Beijing Quality Center GB/T19001-2000 -ISO9001: 2000 quality certification. We can also supply B750L structure steel for cold forming deep processing service for products B750L structure steel for cold forming like cutting, drilling, bending, welding and grinding.

The yield strength of B750L structure steel for cold forming A32, D32, E32, F32 is not less than 315N/mm^2, and the tensile strength is 440~570N/mm^2. The grades A, D, E and F indicate that they can be 0 and -20 respectively. The impact toughness can reach -40℃, -60℃.

Grade E, Grade EH32, Grade EH36 series shipbuilding steel products have good comprehensive mechanical properties, welding performance, process performance. Our shipbuilding steel plate and B750L structure steel for cold forming steel sections are suitable for manufacturing structural parts such as ship hull structures, docks, oil production platforms, marine transmission pipelines, coastal power plants, wharf facilities in ocean, coastal and inland navigation areas.

Hydrogen (H) is the most harmful element in general steel such as B750L structure steel for cold forming. Hydrogen dissolved in steel will cause hydrogen embrittlement, white spots and other defects. Hydrogen, like oxygen and nitrogen, has very little solubility in solid steel. It dissolves into liquid steel at high temperature, and accumulates in the structure without time to escape when cooling, forming high-pressure micro pores, which greatly reduce the plasticity, toughness and fatigue strength of steel, and even cause cracks and brittle fracture in severe cases. "Hydrogen embrittlement" mainly occurs in martensitic steel, but not very prominent in ferrite steel, and generally increases with hardness and carbon content.
