The typical hardness of NM500 steel plate is 500 HBW, so it can withstand severe wear. NM500 steel plate is very suitable for working in strong wear environment, such as high strength ore and corrosive materials. NM550 steel plate is a kind of wear-resistant steel plate with an average hardness of 550 HBW. CCS A40 bulk ore carrier steel Its toughness is the same as that of NM500 steel plate, and it is used in high wear occasions. When the NM500 steel plate is upgraded to NM550 steel plate, the Brinell hardness is increased by 50 units, and the wear resistance life is prolonged without losing the toughness of the CCS A40 bulk ore carrier steel steel plate.
Over the years, the company has established a standard of CCS A40 bulk ore carrier steel steel products pre-sale, in sale and after-sale service, which meets customers' needs in all aspects and in the whole process, so that our products and services are deeply trusted by customers, and has established a long-term cooperation and mutual benefit relationship with customers. The company adheres to CCS A40 bulk ore carrier steel quality surpervision, comprehensively implements quality management, strictly controls the whole process of product from contract signing to after-sales service.
The company has strong technical force, complete production equipment, advanced production technology, perfect testing methods, and high-quality products CCS A40 bulk ore carrier steel. Today, the company will further expand its scale on the existing basis, with first-class products and better service, to make new friends from all over the world, hope that we will work together to create brilliant! Serve our customers with the concept of "being honest and operating with integrity"!
For low alloy high strength steel, the addition of small amounts of V, Ti, Nb, AI and other grain refining elements not only further improves the strength, but also improves the toughness of the steel. In CCS A40 bulk ore carrier steel, low alloy high strength steel, rare earth element Re is sometimes added to eliminate harmful impurities in the steel, improve the shape and distribution of inclusions, and weaken its cold brittleness. A small amount of alloying elements has a significant effect on improving the mechanical properties of steel. For example, adding only 1% Mn to Q235 becomes Q345 steel, but its strength increases by nearly 40% to 345 MPa.
After the order is finished, our after-sales service center will send an email to make a feedback about our steel products' quality. We have phone service every three months to remind our customers of the possible problems and collect advices or suggestions in quality and service. Upon the collection of advices or suggestions, our after-sales service will quickly make technical solutions to wipe out the customer problem.
