Price of alloy steel hardness of SMA490CW

Our 1810mm production line successfully rolled 1.2mm × 1250mm ultra-thin specifications hardness of SMA490CW high strength automotive steel, and the product quality and performance fully met the standards. In recent years, customers have become increasingly demanding for lightweight vehicles. Our company aims at the market and focuses on the development of thin-gauge high strength automotive hardness of SMA490CW steel. The research and development personnel adjusted the product composition based on theoretical calculations and drawing on other experiences to meet customers' higher requirements for automotive steel yield strength and tensile strength.

Hydrogen (H) is the most harmful element in general steel such as hardness of SMA490CW. 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.
