The EN 10025-5 weathering steel S355J0W cold working and aging from BBN

The business department is mainly responsible for communicating with customers, from the manufacturing of steel plates, steel pipes and other products, knowing customers' needs and processing conditions, etc. within the time agreed with customers, the delivery time is short, the price is the most competitive, and the service is the best. Their responsibilities are to deal with customer consultation, solve customer problems, update production plans, and instruct the logistics department to deliver products to customers.

The wear-resistant layer of EN 10025-5 weathering steel S355J0W wear-resistant steel plate is mainly composed of chromium alloy, and other alloy components such as manganese, molybdenum, niobium and nickel are added. The carbide in the microstructure is distributed in the form of fiber, and the direction of the fiber is perpendicular to the surface. The microhardness of carbides can reach hv1700-2000 and HRC58-62 respectively. The alloy EN 10025-5 weathering steel S355J0W carbide has strong stability at high temperature, high hardness and good oxidation resistance. It can be used normally within 500 ℃.

Quenching is a common heat treatment process. It is the metal heat treatment process in which the EN 10025-5 weathering steel S355J0W metal workpiece is heated to a proper temperature and kept for a period of time, then immersed in the quenching medium for rapid cooling. Quenching can improve the strength and hardness of steel in a large range, and adjust the coordination between EN 10025-5 weathering steel S355J0W strength and hardness, plasticity and toughness. Quenching is generally used as the final heat treatment.

The Egypt customer ordered 130 tons EN 10025-5 weathering steel S355J0W stainless steel plate in stock, and this batch has left port today for its destination today(October 25th, 2019). 316l stainless steel is molybdenum-bearing austenitic stainless steel. This material has better corrosion resistant property than 304/314L for it's higher Ni and Mo content. (it is considered to be marine grade stainless steel, not suitable for warm sea water treatment). 316L austenitic stainless steel supplied by our company has good formability and weldablity, additionally it is proved to have excellent properties of tensile, creep and stress-rupture strengths in elevated temperature environment.
