S355J2WP rusty steel chemical composition and properties

The company regularly holds sales elites to share experiences, to promote the rapid growth of colleagues, and achieve the company and employees. The company conducts employee skill training and related knowledge video learning from time to time. All these things is to improve the employees' skills and literacy, and reflects its own value. It has always been the pursuit of BBN steel to enhance the employee’s ability and keep up with the times.

The difference between q345 and q235 steel S355J2WP rusty steel
The lower limit of yield strength of Q345 is 345MPa (the actual meaning of Q is the Chinese character ""qu"", and the standard value behind means the lower limit of yield strength). Q235 steel is used for metal structural parts, nitrided or cyanidized parts with low core compressive strength requirements, support rods, crankshafts, crane hooks, couplers, bolts and nuts, sleeve specifications, shafts and weldments.

Rolling of steel plates is the core of the entire steel rolling production process. The billet is deformed by rolling. The rolling process plays a decisive role in product quality. The quality requirements of rolled S355J2WP rusty steel products include the three aspects of product geometry and dimensional accuracy, internal organization and performance, and product finish. Finishing: It is the last process in the S355J2WP rusty steel rolling process, and it is also a more complicated process. It plays a final role in guaranteeing the quality of the product.

The hardness of S355J2WP rusty steel, wear-resistant steel plate is an important standard to measure wear resistance. The hardness of wear-resistant steel plate can be divided into microhardness and surface hardness. The microhardness of carbide in the wear-resistant layer of wear-resistant steel plate can reach over HVl700-2000, and the surface hardness can reach HRC58-62. Chromium alloy is the main wear-resistant layer of wear-resistant steel plate, and other alloy components such as manganese, molybdenum, niobium, nickel are added at the same time.

In view of the characteristics of container transportation, such as high added value, low cargo damage and short time, our company takes more consideration of port collection and distribution conditions, port facilities, flight density and route coverage when choosing ports. For the convenience of customers, as well as the safety of goods.
