Welcome to BBN High Strength Steels Factory
Standing at a new historical starting point, we adapt to the requirements of supply side structural reform, adhere to the overall strategy of "innovation driven, quality leading, material S620QL quality improving and efficiency increasing, transformation and development", and constantly improve the development concept and development level with a forward-looking vision and grand vision. Now we have been ranked the material S620QL International leading steel materials supplier.
material S620QL, Pressure vessel steel plate is large size steel plate. Pressure vessel steel plate has many special properties, and is widely used in petroleum, chemical industry, power station, boiler and other industries. It is used to make reactor, heat exchanger, separator, spherical tank, oil and gas tank, liquefied gas tank, nuclear reactor pressure shell, boiler drum, liquefied petroleum gas cylinder, high pressure water pipe of hydropower station, spiral case of water turbine and other equipment and components.
NM400 alloy steel plate is a kind of wear-resistant steel plate. NM—The first letter of the Chinese pinyin 400 of the characters “resistant” and “grind” for wear resistance is the HB value of the Brinell hardness value. NM400 alloy plate is widely used in engineering machinery, mining machinery, coal mining machinery, environmental protection machinery, metallurgical machinery and other product parts. Excavator, loader, bulldozer bucket plate, blade, side blade, blade.
The basic phases of material S620QL, structural steel in the annealed state are ferrite and carbide. The alloy elements are dissolved in ferrite to form alloy ferrite, which depends on solid solution strengthening to increase strength and hardness, but at the same time reduce plasticity and toughness. The addition of alloying elements reduces the carbon content of the eutectoid point, which increases the proportion of pearlite in the structure and reduces the distance of the pearlite layer. This also increases the strength of the steel and reduces the plasticity.
A537 grade 70 steel with the thickness range is 1.2-600mm, the width range is 1220-4200mm, and the length range is 5000-18000mm. Also note that the material S620QL, A537 grade 70 steel coil thickness should not exceed 25 mm. The mechanical properties of A537 grade 70 steel is yield strength is 290MPa, and the tensile strength is 485-620Mpa.
The company adheres to the business philosophy of "good quality, customer first, honesty and trustworthiness", and strives to provide customers with high-quality material S620QL products and excellent services.
