The common delivery status of 5mm BP370 bulletproof, SA516 Gr 70 plate is as follows: 1) SA516 Gr 70 plate quenching: the process of rapid cooling after heating to the temperature above the phase transformation point. 2) SA516 Gr 70 plate normalizing: after heating above the phase transition temperature, it is cooled normally (in air). 3) SA516 Gr 70 plate annealing: heating to above the phase transition temperature, cooling slowly. 4) SA516 Gr 70 plate tempering: after quenching, it is heated to a certain temperature (lower than the quenching temperature), kept warm, and then cooled.

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.
