EN steel grade S355K2 material professional supplier

Seamless steel pipe refers to the steel pipe made of a whole piece of metal without joints on the surface. According to the production method, it can be divided into hot rolling tube, cold rolling tube, cold drawing tube, EN steel grade S355K2 material, extrusion tube and spinning tube. According to the shape of the section, it can be divided into two types: circular and irregular. The seamless tube has a maximum diameter of 650 mm (expanding tube) and a minimum diameter of 0.3 mm (capillary tube), which can be divided into thick walled tube and thin walled tube according to the thickness.

Based on the main business of iron and steel, we are committed to producing high-quality, green and efficient steel products. The main steel products are medium and EN steel grade S355K2 material heavy plate, hot rolled coil, section steel, steel tube, etc., which are widely used in automobile, oil, railway, bridge, construction, electricity, transportation, machinery, shipbuilding and other important fields. Our steel products are exported EN steel grade S355K2 material to Indonesia, Bangladesh, Myanmar, Iran, Brazil, Mexico, UAE, Iraq, etc Egypt, Mozambique, Ukraine and other dozens of countries and regions.

In order to improve the EN steel grade S355K2 material corrosion resistance and decoration of steel, it is an important content of steel production method to plating or coating a protective layer on the surface of plastic processed steel. The material of protective layer is divided into metal and non-metal. The metal protective layer adopts the methods of electroplating, hot plating and chemical plating. The main EN steel grade S355K2 material coating metals are zinc, tin, copper, aluminum, chromium, etc., of which zinc plating and tin plating are the most common. Taking EN steel grade S355K2 material sheet metal as an example, there are many hot-dip galvanizing methods used in sheet metal galvanizing. Continuous hot-dip galvanizing is one of the main galvanizing methods used in the world.

The alloying principle of low alloy high strength steel plate mainly uses solid volume strengthening, fine grain strengthening and precipitation strengthening produced by alloy elements to improve the strength of low alloy high strength steel plate, EN steel grade S355K2 material. At the same time, the effect of fine grain strengthening on the reduction of ductile brittle transition temperature of low alloy high strength steel platel is used to offset the adverse effect of carbon nitride precipitation strengthening on the rise of ductile brittle transition temperature of steel, so that low alloy high strength steel plate can obtain high strength while maintaining good low temperature performance.

Both parties shall confirm the EN steel grade S355K2 material material object and the quality of the products, confirm the reasons for the defects and the quality of the products, and sign the quality inspection agreement. Major quality objections shall be reported to relevant leaders in a timely manner, and shall be discussed and solved with the EN steel grade S355K2 material steel plant.
