Factors affecting flame cutting of GB stadard of nm500 steel

Our technical department plays important role in our professional communication with customers, especially those who have high technical requirements for steel materials and those who need complex further processing. Under such condition, our technician department can provide technical support in time, anylize customer design or make drawing according to customer needs rapidly, so that we can proceed smoothly. The profession of our team has won great praise of customers.

Normalizing is a heat treatment that improves the toughness of steel. After the steel components are heated to 30-50°C above the Ac3 temperature, they are kept for a period of time and then air cooled. The main feature is that the cooling rate is faster than annealing but lower than quenching. During normalizing, the crystal grains of the steel GB stadard of NM500 steel can be refined in a slightly faster cooling. Not only can satisfactory strength be obtained, but also the toughness (AKV value) can be significantly improved and reduced The tendency of the component to crack.

GB stadard of NM500 steel 2020 China inventory: 8*2400*12000, 30*3020*7800, 20*1950*9000, 25*2210*9400, 8*2200*11200, 8*2400*12000, 22*3400*13000, 16*2150*10750, 27*3510*10500, 21.5*1630*13480, 13.6*2940*11455, 32*2520*7546, 16*2150*10450, 25*2500*12000, 8*2400*12000, 32*2500*6000, 16*2150*10350, 330*2200*4250, 22*3400*13000, 32*2500*6000, 12.9*2987*10384, 25*2700*9000, 14*1950*10000, 55*2200*8000, 13.6*2940*11455.

The wear-resistant plate GB stadard of NM500 steel shows good wear resistance: the chemical composition of the alloy layer contains 4-5% carbon and 25-30% chromium. The volume fraction of Cr7C3 carbide in the metallographic structure is more than 50%, the macro hardness is HRC56-62, and the hardness of chromium carbide is HV1400-1800. Because of the vertical distribution of carbides in the wear direction, the wear resistance of the cast alloy with the same composition and GB stadard of NM500 steel hardness is more than twice as that of the cast alloy with the same composition and hardness. Compared with several typical materials, the wear resistance is as follows: (1) compared with low carbon steel; 20-25:1 (2) with as cast high chromium cast iron; 1.5-2.5:1.

The results of adopting two-level GB stadard of NM500 steel service system and implementing standardized management are mainly reflected in the formation of vigorous work style such as quick response and quick action. Our company's customer service center stipulates that employees must be accurate and quick in technical support and GB stadard of NM500 steel after-sales service. Through the formation of this fast, agile, vigorous style, to provide users with satisfactory service.

Our steel products are widely used in petroleum and natural gas, chemical industry, shipbuilding, automobile manufacturing, power generation, mining, and other industries. The products GB stadard of NM500 steel are sold in more than 20 provinces, cities and all over the world. The company has strong technical force, complete production equipment, advanced production technology, perfect testing methods, and high-quality products.
