weldability of nm400 plate is required to have high toughness

Automobile steel sheet is mainly used to manufacture automobile girders (longitudinal and cross girders), frame and other structural parts. The automobile girder should not only bear heavy static load, but also bear certain impact, vibration, etc., so the steel sheet weldability of NM400 plate is required to have certain strength and fatigue resistance, as well as better stamping performance and cold bending performance to meet the requirements of cold stamping processing.Our company is China's 10th largest supplier & Exporter of stainless steel, carbon steel plate and section, alloy steel plate and pipes We are specialized in stocking & distributing various Stainless Steel, carbon steel plates, angle steel, H beam steel to worldwide for specific & urgent requirements We have a fully advanced and modernized warehouse that stores tonnes of our value-adding products, which we source out from the mills that are compliant with the universal guidelines for plate production,weldability of NM400 plate.The correct choice of billet type, section shape, size and weight are of great significance to steel rolling production. Steel rolling production has certain technical requirements for raw materials, such as steel type, section shape, size, weight, and surface quality. The consideration of these technical requirements is necessary to ensure the quality of steel. It should also be specifically considered when determining and selecting the blank. The rolling method can be divided into cold rolling and hot rolling according to the rolling temperature.Weldability of NM400 plate,Temperature has a great influence on the strength of the material. When the temperature exceeds a certain value, the strength limit of the steel will be reduced. The higher the temperature, the lower the strength. In addition, the longer the steel is used at high temperature, the lower the strength. Therefore, if the steel works at high temperature for a long time, the instantaneous strength of the steel can not be used as its performance index, nor can the room temperature performance replace the high temperature performance.weldability of NM400 plateWeldability of NM400 plate,The company has passed the ISO9001: 2008 quality system certification, strictly implemented the ISO9001 quality management system. Besides, we have continuously improved the after-sales service network to make every effort to provide more convenient, accurate and faster services for all customers. We will supervise the production, control the quality in the factory, Inspect the cargo before shipment, Issue the test report to sales department. From the steel prodcution to steel delivery, we always focus the whole process.
