The company adheres to the service concept of "you give the order to me and I leave the satisfaction to you". Over the years, our A572 Gr 55 high strength steel steel products are supplied in time, with reliable quality and perfect and thoughtful after-sales service. Meanwhile, we have huge A572 Gr 55 high strength steel steel stocks all the year round. The company long-term pursues the principle of quality first, customer first, quality for survival, reputation for development, and perfect service to win the users.
A572 Gr 55 high strength steel, AR400 wear-resistant plate is a special structural steel plate with high wear resistance, and is an important high-tech wear-resistant steel material. After quenching or quenching and tempering heat treatment, AR400 wear-resistant plate has a dense martensite or martensite-bainite microstructure. The thickness of AR400 wear-resistant plate can reach 100mm. The AR400 wear-resistant plate is widely used in loading machinery, construction machinery, agricultural machinery, mining machinery, metallurgy, electric power and other fields.
The boiler steel plate has small strain aging sensitivity, especially in the corresponding working temperature range, a certain value of aging impact energy must be guaranteed;The boiler steel plate has low notch sensitivity, which can prevent steel from cracking in welding, opening, and local stress concentration areas;The A572 Gr 55 high strength steel, boiler steel plate has good welding performance;The A572 Gr 55 high strength steel, boiler steel plate has a good microstructure, white spots and cracks are not allowed.
With the increase of temperature, the yield limit of A572 Gr 55 high strength steel will decrease monotonically, but the tensile strength of A572 Gr 55 high strength steel will rise to a high peak value at a certain temperature, and then decrease. This peak temperature is called the blue brittleness temperature of A572 Gr 55 high strength steel. Near the blue brittleness temperature, the A572 Gr 55 high strength steel strength increases and the plasticity decreases. The elongation and section shrinkage of A572 Gr 55 high strength steel increase with the increase of temperature, but there is a low peak at the blue brittleness temperature. The blue brittleness temperature of low carbon steel ranges from 200 ℃ to 250 ℃. The blue brittleness of low alloy steel is not obvious as that of low carbon steel, and the blue brittleness temperature is higher.
DIN 17100 St37-2 steel plate belongs to the carbon and low alloy high strength steel plate. We can supply the different sizes of A572 Gr 55 high strength steel, DIN 17100 St37-2 steel plate. And the rolling size of DIN 17100 St37-2 steel plate is following: the thickness range is 1.2-600mm, the width range is 1220-4200mm, and the length range is 5000-18000mm. Also note that the DIN 17100 St37-2 steel coil thickness should not exceed 25 mm.
We have replenish steel materials stocks, now there are huge stocks of S355JR, A36, A572 Gr 55 high strength steel A572 Gr 50, 16Mo3, A516 Gr 70, ABS grade A, AH32, AH36, EH36, SPA-H, SG295,SM700C etc steel materials. We can arrange delivery for those stock steel products within short time. Meanwhile, we also provide further processing for the A572 Gr 55 high strength steel steel materials, such as cutting, drilling, bending, welding, etc. Please do not hesitate to contact us if you have any steel demands.
From the order to the delivery, there are three quality inspections to ensure that the qualified rate of finished products is more than 100%. We promise that every order will be tracked in a timely manner to ensure that customers can receive goods safely and constantly listen to their opinions and suggestions, reflect on our own problems, and let customers feel at ease. We have a large warehouse in Shanghai and Tianjin, which can provide customers with sufficient sources of supply.
