BBN steel a professional cold rolled coils and galvanized steel sheets supplier in China. DC51D+AZ 55% AI-Zn galvanized steel sheet for appliances nominal thickness: 0.22~2.0; width: 700~1300; length of steel plate: 1000~6000; Inside diameter of steel strip: 508mm. It is mainly used for cold forming. With the alloy galvanized coating, the recommended nominal coating weight is 30/30, 40/40, 50/50, 60/60, 75/75, 90/90g/m².

The boiler steel plate has small strain aging sensitivity, especially in the corresponding working temperature range, a certain value of aging impact energy must be guaranteed;The boiler steel plate has low notch sensitivity, which can prevent steel from cracking in welding, opening, and local stress concentration areas;The SM400C carbon steel material, boiler steel plate has good welding performance;The SM400C carbon steel material, boiler steel plate has a good microstructure, white spots and cracks are not allowed.

Hydrogen (H) is the most harmful element in general steel such as SM400C carbon steel material. 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.

SM400C carbon steel material, HP265 steel with the thickness range is 1.2-12mm. HP265 steel’s mechanical properties is include the yield strength more than 265MPa, tensile strength is 410-520MPa. The chemical composition of HP265 steel is C element content is 0.18, the Si element content is 0.10, the Mn element content is 0.80, the P element content is 0.025% max, the S element content is 0.015% max.
