nm400 material vs A572 Grade 50 steel

SA516GR70N steel is a standardized medium and low temperature pressure vessel. The overall performance is improved and the NM400 material product price is higher. The steel plate has the following characteristics: good impact resistance, low temperature deformation, good welding performance, good fatigue resistance, good anti-laminar cracking performance, low carbon equivalent, and strong resistance to sulfur and hydrogen. The products available for steel plates with a thickness of less than 200mm.

BEBON cpompany practice new development concepts, expand in an all-round way, deepen reform and innovation, speed up transformation and upgrading, become stronger, better and bigger, accelerate the implementation of BEBON Steel's NM400 material industrial planning, and realize the revitalization and development of enterprises.Fully implement the corporate NM400 material market dominant position, comprehensively promote contractual management, and promote the transition from "internal production" to "market operation”.

If the chromium content in NM400 material alloy steel reaches about 12%, dense chromium oxides will be formed on the surface of the steel, which will greatly improve the corrosion resistance of steel in oxidizing media. Chromium, aluminum, silicon and other elements can improve the oxidation resistance of steel and the corrosion resistance of high-temperature gas, but excessive aluminum and silicon will deteriorate the thermoplasticity of steel.

The basic principle of NM400 material, heat treatment of steel: put the metal workpiece in a certain medium and heat it to a suitable temperature, keep it in this temperature for a certain time, and then cool it at different speeds. Objective: to obtain the desired structure and properties by means of heating, heat preservation and cooling, so as to make the metal workpiece have the required mechanical, physical and chemical properties.

Our company will accept the product quality objection registration record, pass it to the NM400 material production unit and relevant departments, and timely coordinate the supervision of product NM400 material quality objection. Our company coordinates the relevant department personnel to the customer unit to carry on the investigation, the processing.
