When 321 stainless steel contains about 18% Cr, 8% to 25% Ni, and about 0.1% C, it has a stable austenite structure. Austenitic chromium-nickel stainless steel includes the famous 18Cr-8Ni steel and high Cr-Ni series steel developed by adding Cr and Ni content and adding Mo, Cu, Si, Nb, Ti and other elements on this basis. Because 321 stainless steel has comprehensive and good comprehensive properties, it has been widely used in all walks of life.
The main advantage of 20CrMo alloy steel plate is reflected in its various physical and chemical properties. For 20CrMo alloy plate, the main component is alloy, and the physical and chemical properties of alloy GL-EH 36 offshore engineering steel are generally, a single metal is better, and its performance is stronger. The main features of 20CrMo alloy steel plate are high precision, rigidity, high temperature and high pressure resistance, not easy to corrode and other characteristics.
Advantages of hot rolling: hot rolling can destroy the casting structure of ingot, refine the grain of steel and eliminate the defects of microstructure, so that the steel structure is dense and the mechanical properties are improved. This improvement is mainly reflected in the rolling direction, so that the GL-EH 36 offshore engineering steel steel is no longer isotropic to some extent; the bubbles, cracks and looseness formed during pouring can also be welded under the action of high temperature and pressure.
The company has sufficient stocks and complete specifications. The common carbon steel plates, marine plates, GL-EH 36 offshore engineering steel and storage tank steel plates sold are all produced by large state-owned steel companies such as Shougang, Hegang, Taiyuan Iron and Steel, with quality assurance and worry-free after-sales. The company develops and grows under the concept of seeking innovation in stability and advancing with the times for development. After a short period of development, it has begun to take shape.
Both parties shall confirm the GL-EH 36 offshore engineering steel material object and the quality of the products, confirm the reasons for the defects and the quality of the products, and sign the quality inspection agreement. Major quality objections shall be reported to relevant leaders in a timely manner, and shall be discussed and solved with the GL-EH 36 offshore engineering steel steel plant.
