Based on the main business of iron and steel, we are committed to producing high-quality, green and efficient steel products. The main steel products are medium and sa573 grade 65 [450] carbon plate steel sheet heavy plate, hot rolled coil, section steel, steel tube, etc., which are widely used in automobile, oil, railway, bridge, construction, electricity, transportation, machinery, shipbuilding and other important fields. Our steel products are exported sa573 grade 65 [450] carbon plate steel sheet to Indonesia, Bangladesh, Myanmar, Iran, Brazil, Mexico, UAE, Iraq, etc Egypt, Mozambique, Ukraine and other dozens of countries and regions.
Alloy plate is a kind of steel plate with high thermal strength and oxidation resistance at high temperature, which has certain hydrogen corrosion resistance. Alloy plate is a new type of steel plate formed by adding other elements on the basis of steel plate material, which is to solve the problems existing in ordinary carbon steel plate. Alloy plate can be divided into bridge steel plate, boiler steel plate, shipbuilding steel plate, armored steel plate, automobile steel plate, roof steel plate, structural steel plate, silicon steel sheet, spring steel plate, sa573 grade 65 [450] carbon plate steel sheet, etc.
Bridge steel plate is specially used for erecting railway or highway bridges. sa573 grade 65 [450] carbon plate steel sheet, bridge steel plate is required to have high strength and toughness to bear the load and impact of rolling stock, and have good fatigue resistance, certain low temperature toughness and atmospheric corrosion resistance. The bridge steel plate used for bolt welding bridge should also have good welding performance and low notch sensitivity.
The basic phases of sa573 grade 65 [450] carbon plate steel sheet, 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.
Hardness comparison between Q345B steel and NM450 steel: wear resistant steel for construction machinery requires high wear resistance, high toughness, impact resistance, easy welding, easy forming and other high-performance characteristics. The main index of wear resistance is the surface hardness. The higher the hardness, the better the wear resistance. Compared with sa573 grade 65 [450] carbon plate steel sheet, Q345B steel, the hardness of NM450 steel is only increased 3 times, but the average service life is increased 6-8 times under the same working conditions.
The boiler steel plates are among our main products. Other than standard size boiler steel plates, we also provide sa573 grade 65 [450] carbon plate steel sheet cutting, bending and so on processing to change plate size and shape according to your requirements. Welcome to consult us about sa573 grade 65 [450] carbon plate steel sheet ASTM A204 grade B properties, SA 516 gr 70 temperature range, ASTM A285 grade C chemical composition, boiler steel price and so on questions and ask for offer.
First of all, we should establish a correct concept of after-sales service. Service concept is an important part of corporate culture and a long-term enterprise value concept. Our company's after-sales service embodies the concept of "customer first, sincere service for customers". As long as we are in the "sincere service for users" under the guidance of the idea, I believe we will get rich returns.
