The alloy elements in quality 09CuPCrNi-B steel

VLE460 steel plate grade analysis: "VL" stands for the abbreviation of "DNVGL", which is the standard certified by the two classification societies of DNV (Norway) and GL (Germany). VL E460 hull steel characteristics: good welding and other properties. It is suitable for repairing ships and main structures of naval vessels. Naval steel is required to have higher strength, better toughness, blast resistance and resistance to deep water collapse.

The company mainly supplies quality 09CUPCRNI-B steel steel materials, and has a large amount of inventory all year round. We can process and cut all kinds of special-shaped steel parts according to your requirements, and we can arrange fresh production for all kinds of quality 09CUPCRNI-B steel steel materials in customized specifications. The company adheres to the core values of "quality and benefit, integrity and win-win, innovation and efficiency", and provides first-class services. Based on the principle of reputation first, small profits and high sales, we develop the market with high-quality services and flexible business model.

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 quality 09CUPCRNI-B 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 quality 09CUPCRNI-B steel rolling process, and it is also a more complicated process. It plays a final role in guaranteeing the quality of the product.

Oxygen is a harmful element in quality 09CUPCRNI-B steel steel. With the increase of oxygen content, the strength of quality 09CUPCRNI-B steel steel increased, but the plasticity, especially the toughness, decreased significantly, and the weldability became worse. The presence of oxygen causes hot brittleness of quality 09CUPCRNI-B steel steel.
