Over the years, the company has trained a number of professional sales talents, enriched the concept of various marketing and customer service, and strengthened the business strength of the company. Now the company's business A633 Grade D metal steel carbon-manganese-silicon steel grade department, marketing department and information department constitute the market development network; the finance department, personnel department, logistics department, shipping department, document department and A633 Grade D metal steel carbon-manganese-silicon steel grade after-sales service department constitute the service customer network.
The steel plate used for containers and pressure vessel has to bear different pressures and strengths due to the manufactured containers. The normal pressure is generally 31.4MPa or higher; the working temperature is usually between -20 ℃ -450 ℃, and sometimes lower than -20 ℃. According to the working conditions and processing technology of the container, the A633 Grade D metal steel carbon-manganese-silicon steel grade, steel plate used for the container must have good cold bending and welding performance. Besides, it should have good plasticity and toughness, high temperature short-term strength or long-term strength performance.
The wear-resistant layer of A633 Grade D metal steel carbon-manganese-silicon steel grade wear-resistant steel plate is mainly composed of chromium alloy, and other alloy components such as manganese, molybdenum, niobium and nickel are added. The carbide in the microstructure is distributed in the form of fiber, and the direction of the fiber is perpendicular to the surface. The microhardness of carbides can reach hv1700-2000 and HRC58-62 respectively. The alloy A633 Grade D metal steel carbon-manganese-silicon steel grade carbide has strong stability at high temperature, high hardness and good oxidation resistance. It can be used normally within 500 ℃.
Alloy elements have the most significant strengthening effect on steel in quenched and tempered state. The primary purpose of adding alloying elements to steel is to improve the hardenability of steel and to ensure that martensite is easily obtained during quenching. The second is to improve the tempering stability of the steel to keep the martensite at a higher temperature, so that the carbides precipitated during the tempering of the quenched steel are finer, uniform and stable. In this way, under the same conditions, alloy steel has higher strength than carbon steel, A633 Grade D metal steel carbon-manganese-silicon steel grade.
ST37-2 is a kind of low carbon steel with carbon content of 0.20%, similar to S235JR or Q235 A633 Grade D metal steel carbon-manganese-silicon steel grade. It's not as strong as common ASTM A36, but it is also widely applied by everyday uses and structural applications where high strength is not so important. Equal ST37-2 angle steel size: A633 Grade D metal steel carbon-manganese-silicon steel grade Size: 20 × 20 mm to 200 × 200 mm. Thickness: 3 - 35 mm. Length: 6 m, 9 m or as required. Unequal ST37-2 angle steel size: A633 Grade D metal steel carbon-manganese-silicon steel grade Size: 30 × 20 mm to 250 × 90 mm. Thickness: 3 to 10 mm. Length: 6 m, 9 m, 12 m or per your request.
