impact resistance of nm400 steel plate Normalized Plate

Our pipeline products adopt the national standard and the international standard API 5L, which can meet the needs of impact resistance of NM400 steel plate pipelines working in different environments-on land in the open air and offshore deep water. Acid-resistant pipelines are produced for transporting highly acidic crude oil.

With high-quality impact resistance of NM400 steel plate steel and professional services, we have won international praise in infrastructure, shipbuilding, oil and other industries, and gradually grow into a bright star in the steel export industry, while winning unanimous praise from foreign customers. It has laid a foundation for the development of our impact resistance of NM400 steel plate steel market and improved the control of steel plate production quality.

Weathering steel generally adopts the process route of fine material into the furnace-smelting (converter, electric furnace-microalloying treatment-argon blowing-LF refining-low superheat continuous casting (feeding rare earth wire)-controlled rolling and cooling. The scrap steel is added into the furnace together with the charge, and smelted according to the conventional process. After the impact resistance of NM400 steel plate steel is tapped, deoxidizers and alloys are added. After the molten steel is treated with argon blowing, the molten steel is cast. By adding rare earth elements to the steel, the impact resistance of NM400 steel plate weathering steel is purified and the content of inclusions is greatly reduced.

impact resistance of NM400 steel plate controlled rolling is that, on the basis of adjusting the chemical composition of impact resistance of NM400 steel plate, by controlling the heating temperature, rolling temperature, deformation system and other process parameters, the change law of austenite structure and the microstructure of phase transformation products are controlled, so as to achieve the purpose of refining the structure and improving the strength and toughness of impact resistance of NM400 steel plate.

Due to other non-steel quality reasons caused by the customer dissatisfaction, to timely explain to the customer, and help them solve the problem, for the customer really because of their own reasons, to give patient reply.The process of objection handling is the process of our technical service.
