What is the asme material hardox 400 machining equivalent

Quenching is a common heat treatment process. It is the metal heat treatment process in which the HARDOX 400 machining metal workpiece is heated to a proper temperature and kept for a period of time, then immersed in the quenching medium for rapid cooling. Quenching can improve the strength and hardness of steel in a large range, and adjust the coordination between HARDOX 400 machining strength and hardness, plasticity and toughness. Quenching is generally used as the final heat treatment.

The company adopts the HARDOX 400 machining international advanced management system, and has passed the certification of ISO9001 quality management system, ISO14001 environmental management system and GB / T28001-2001 occupational health and safety HARDOX 400 machining management system, and has realized the comprehensive integration of the three systems.

Novel coronavirus pneumonia has been closed in recent years, and Pohang iron and Steel Co., Ltd. closed its overseas processing center in Italy, Malaysia, Philippines and India. At the request of the Italian government, all production activities will be stopped except for the necessary HARDOX 400 machining products. POSCO-ITPC, an Italian stainless steel cold rolling mill near Verona in northeast Italy, is scheduled to close from March 26 to April 3.

The thickness of the wear-resistant layer is uniform and the surface is smooth. The flatness of the whole wear-resistant steel plate is equivalent to that of the ordinary carbon steel plate, HARDOX 400 machining. There is a stress release crack on the surface of the wear-resistant layer, which only exists in the hardfacing layer and does not extend into the matrix. The stress release crack can greatly reduce the residual stress and deformation of the matrix during the surfacing process, thus avoiding the reduction of the matrix strength and not affecting the service performance of the wear-resistant steel plate.
