China professional xar400 wear resistance material supplier

xar400 wear resistance material, Large diameter spiral steel pipe refers to the relatively large diameter spiral steel pipe, which is generally required to be more than 1000mm. The manufacturing process of large-diameter spiral steel pipe: first, the steel strip is bent into shape, and then welded together to make a large-diameter spiral steel pipe of specified size. After being processed into a pipe, hydrostatic test, bending, flattening and other tests shall be carried out, and the internal steel support of large-diameter spiral steel pipe can be made according to customer requirements.

The company is a leading company that sells xar400 wear resistance material steel plate products in the Central Plains region and has a high reputation in the steel plate industry. Since its establishment, the company has always adhered to the business philosophy of "integrity cooperation and common development", and has sold xar400 wear resistance material steel products with various materials. The products are widely used in petroleum, chemical, construction, boiler, decoration, offshore operations, electric heating, gravity machinery and other industries.

Normalizing is to heat the steel parts to 30~80℃above the critical temperature for a period of time. Then the parts are taken out of the furnace and cooled in air. Since the cooling rate of normalizing is faster than that of annealing, the strength and hardness of normalized xar400 wear resistance material are higher than that of annealed xar400 wear resistance material, but the elimination of internal stress is not as good as annealing. The normalizing operation of xar400 wear resistance material is simple, the cost is low, the productivity is high, and it is widely used in actual production.

The effect of nitrogen (N) on the properties of xar400 wear resistance material and so on steel is similar to that of carbon and phosphorus. With the increase of nitrogen content, the strength of steel can be significantly improved, especially the plasticity, especially toughness, and the weldability will be decreased, and the cold brittleness will be intensified. At the same time, aging tendency, cold brittleness and hot brittleness will be increased, which will damage the weldability and cold bending property of steel. Therefore, the nitrogen content in xar400 wear resistance material and so on steel should be reduced and limited as much as possible. Generally, nitrogen content should not be higher than 0.018%.
