St37-2 carbon steel plate sheet plate specification
Q355NHE grade is a weather-resistant structural steel used in construction, bridges, and railway vehicles. Q represents yield strength, NH represents weather resistance, and E represents quality grade (A, B, C, D, E) composition. Q355NHE is an atmospheric corrosion-resistant steel plate, also called weather-resistant steel plate. It has the properties of high-quality steel such as strength, ductility, forming, welding, abrasion, high temperature, and fatigue resistance.
Since it was established in 2000. Based on the domestic rich St37-2 carbon steel plate sheet product resources and the great steel demand of the international market, our St37-2 carbon steel plate sheet service has already spread many countries in Europe , America, Southeast Asia, Middle East, South America, Africa, etc, and we have won an outstanding reputation for its professional exporting steel products
S355J2 steel plate rolling process is controlled rolling process. In the rolling process, the ingot rolling temperature is 1000-1050℃; in the first stage, the low-speed and large reduction rolling process is adopted, the high-temperature stage is 950-1000℃, the St37-2 carbon steel plate sheet rolling speed is 1.6-2.0m/s, the single reduction rate is 15-20%, and the cumulative reduction rate is 40-45%, so as to ensure sufficient deformation of ingot. In the first stage, the start rolling temperature is 910-930℃, and the finish rolling temperature is ≤ 870℃.As a basic building material, steel plates are currently widely used in automobiles, shipbuilding, chemical industry, aerospace and other fields. Reasonable selection of flaw detection methods to ensure the quality of St37-2 carbon steel plate sheet steel plates is of great significance to safe production. Common defects of steel plates are folding, inclusion, shrinkage, air bubbles, delamination and cracks. These problems can be discovered in time through flaw detection.
St37-2 carbon steel plate sheet, Nickel-based alloys are widely used in petrochemical, metallurgy, energy, and machinery because of their high room temperature and high temperature strength, good oxidation and thermal corrosion resistance, excellent creep and fatigue resistance, good structural stability and reliability. , Building materials, medicine, environmental protection and other industries. The company has developed N08825, N06625, N06600, N06690, N06601 and other nickel-based alloy tube blanks and steel pipe products, which have been implemented in batches in the petrochemical industry.
As one of the large professional metallurgical manufacturers in China, the strength of the brand, quality assurance, professional after-sales. Every day we are making unremitting efforts to challenge higher quality St37-2 carbon steel plate sheet products and more satisfactory services. Customer demand is our pursuit, and win customer satisfaction with quality. BBN after-sales team is responsible to solve the problem of technical support and quality, service complaints.
