The company has A514 grade B QT steel plate advanced production equipment and machining technology, excellent marketing team and domestic regional channel partners, and sound management plan for product market development and after-sales service. After years of cooperation experience A514 grade B QT steel plate, we have accumulated a large number of customers at home and abroad, and won unanimous praise.
High strength wear-resistant steel plates are used in mining equipment, cement machinery, metallurgical machinery, construction equipment, ship equipment, electrical equipment, port equipment, transportation and general machinery manufacturing industries. High strength wear-resistant steel plates are used by more and more enterprises because of their excellent wear resistance and the convenience of processing and using. The company has sufficient stocks of high strength wear-resistant steel plates, A514 grade B QT steel plate with complete varieties and specifications.
Ordinary carbon steel killed steel plate deoxidizes the liquid steel before making. When the liquid steel is poured into the ingot, its reaction is relatively calm and there is no boiling state. Advantages: this kind of steel plate A514 grade B QT steel plate has no gas, less impurities, uniform stress and good welding performance. Widely used in demanding parts
Hydrogen (H) is the most harmful element in general steel such as A514 grade B QT 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 B QT steel plate, SS400 steel is one of the most commonly used hot rolled general structural steel. SS400 steel’s mechanical properties is yield strength more than 225-235MPa, tensile strength 360-510Mpa and 340-470Mpa. For SS400 steel, the C element content is 0.2% max, the Mn element content is 1.40% max, the P element content is 0.045% max, the S element content is 0.045% max.
The company has a high-quality management, technology and R&D team, and adopts independent research and development, domestic innovative process optimization combination. Relying on advanced manufacturing technology and sophisticated production testing equipment, it has ensured the high quality of products A514 grade B QT steel plate and won a good reputation.
