A709Gr50 steel is a high-strength low-alloy stee. It is widely used in engineering structures, such as building steel structures, construction machinery, mining and mountain machinery, trucks, bridges, pressure vessels, especially for those requiring good weldability and toughness Construction and construction machinery parts. BBNsteel’s engineers suggest customer choose low temperature impacting test for steel A709 grade 50 at zero centigree, because these steel plates A709Gr50 normally used in this temperature.

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 EN 10025 S460M steel plates alloy steel EN 10025 S460M steel plates 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.

Heat treatment process: heat treatment refers to a kind of process operation in which the metal or alloy can change the internal structure through certain heating, heat preservation and cooling methods in the solid range to obtain the required performance. EN 10025 S460M steel plates Heat treatment process refers to the ability to change the microstructure and properties of EN 10025 S460M steel plates after heat treatment, including hardenability, hardenability, temper brittleness, etc.

EN 10025 S460M steel plates, Q690D steel is a high-strength welded structural steel grade. Q the first letter of the Chinese spelling of Qu for the yield strength of steel; 690 represents the yield strength value, the unit is MPa, and D represents the grade of the steel plate; -20 ; common steel plate quality grade steel plates are Q690A, Q690B, Q690C, Q690D, Q690E.

After-sales service team is a key department to test the steel quality. Product quality is always the foundation of our survival and development. The company's full inspection from raw materials to finished products; and implements standardized, scientific, and strict internal quality control and management systems in accordance with the process flow during the production process; products can only leave the factory if qualified, and follow-up problem solving systems are implemented in after-sales services to guarantee the customers’ interest.
