After 1975, our equipment includes blast furnaces, electric furnaces, vacuum refining furnaces, and electroslag furnaces. The product varieties are relatively complete. Plates, A572 Gr 42 high strength steel tubes, wires, belts, and profiles have a certain scale, including magnetic, elastic, expanded, bimetal and other precision alloy materials for national defense and electronics industries. In 1982, these plants produced 364,000 tons of A572 Gr 42 high strength steel steel and 542,000 tons of steel.
Our after sales department is an very important part of our department structures. After the customer receive steel materials, our after sales department will follow up regularly and solve problems for them in time if they have the needs. We romise to return the goods for free for its lifetime if it is quality of the steel material itself. Meanwhile, if you have any advice or complaints, also welcome to feed back to our after sales department, and we are trying to give better service to you.
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.
Steel transportation because of the special material of A572 Gr 42 high strength steel steel, is a metal with "iron" as the main basic element, small volume and large weight, and easy to oxidize and rust when contacting with air and rain water, so there are many precautions in the transportation of steel. There are 11 proverbs for steel transportation: "evenly placed, moisture-proof and rust proof". Our company chooses the logistics aspect to be very rigorous, takes the customer's request as the standard, guarantees the steel product quality.
A572 Gr 42 high strength steel, Hardened wear-resistant plate refers to the low-alloy steel plate that is hardened by quenching during the rolling process or the low-alloy steel plate is heat treated and hardened. The hardness is generally HB350-500. The wear-resistant layer of the bimetal wear-resistant plate is of high alloy composition. There are a large number of high-hardness alloy carbides (about HV1600) embedded in the matrix in the metallographic structure, which are the main carbides that play a role in anti-wear. The actual micro hardness of the wear-resistant layer is much higher than the measured macro hardness, and its strengthening method is the same as that of cemented carbide.
Our company has been established for 20 years and has accumulated rich experience in steel products. At the same time, it is often exported to Southeast Asia, Africa, South America and other countries. So you can rest assured that our A572 Gr 42 high strength steel products and our prices are very favorable. Because we have our own factory, there is no other cost, we can also carry out machining and so on.
We should focus on the main problems to be solved and pay attention to efficiency. After receiving the user's quality objection report data, the possible causes, responsible units, compensation amount, etc. of the problem shall be judged based on experience. To have a clear service plan, to be clear about what your main problem is, what technical support is needed, these should be prepared.
