Hydrogen (H) is the most harmful element in general steel such as A514 grade F steel plate. 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.
A514 grade F steel plate and SM490B steel plate belongs to low alloy high strength steel, which is a kind of structural steel produced according to Japanese Standard JIS G3106. Its strength σb is 490MPa. A514 grade F steel plate, SM490B steel plate is mainly used in buildings, bridges, ships, rail vehicles, oil storage tanks, containers and other buildings requiring advanced weldability.
The 365 day service system is implemented, and the business, loading and delivery are handled as usual in holidays and festivals. Actively help users solve difficulties. When users encounter difficulties in handling business, they should actively coordinate with the external solution; if they need to solve the problems internally, they should solve them in a timely manner without prevarication and wrangling. In line with the A514 grade F steel plate principle of "fairness, justice and timeliness", coordinate with relevant departments and deal with all kinds of objections in a timely manner.
