The SM570 steel plate has a yield strength of more than 460MPa and a 60Kg strength grade steel because it contains a variety of alloying elements, including microalloying elements, and can often achieve higher strength in the state of hot rolling or controlled rolling, but the impact toughness fluctuates greatly. P235GH steelnumber product Normalizing has the advantages of uniform and stable steel structure and performance, high qualification rate, and easy control of the production process.

Compared with 15Cr steel, 20Cr alloy has higher strength and hardenability. The critical hardening diameter in oil is 4-22mm, and the critical hardening diameter in water is 11-40mm, but the toughness is poor. This p235gh steelnumber alloy steel p235gh steelnumber still has a tendency to grow grains during carburization, and direct quenching at lower temperature has a greater impact on impact toughness, so secondary quenching is required after carburization to improve the toughness of the core of the part, and there is no temper brittleness.

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 p235gh steelnumber 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 accumulated rich experience in long-term cooperation with new and old customers, which makes our products p235gh steelnumber more unique in the same industry, and is favored and praised by users. We always adhere to the enterprise spirit of "integrity, dedication, and people-oriented" and the business philosophy of "creating benefits for users". As a leading international steel supplier, BEBON have two warehouses which are near by Tianjin port and Shanghai port.

The after-sales service department will pay return visit to each customer by call or email, report problems found during the return visit in time, and discuss with the production and quality inspection center to propose effective solutions and follow up in a timely manner, so as to ensure the benefits each customer are fully guaranteed, and to provide customers with more value-added services.
