Manufacturing method of 12Cr1MoVR alloy: This plate is melted in oxygen top blown converter, open hearth furnace or electric furnace. After negotiation with the demander, other equivalent methods can also be adopted. ABS E40 hull structural steel, 12Cr1MoVR alloy steel plate is usually delivered in normalized + tempered state. According to the special agreement at the time of ordering, 12Cr1MoVR steel plate can also be delivered in Annealed or tempered state.
The company adheres to the service concept of "you give the order to me and I leave the satisfaction to you". Over the years, our ABS E40 hull structural steel steel products are supplied in time, with reliable quality and perfect and thoughtful after-sales service. Meanwhile, we have huge ABS E40 hull structural steel steel stocks all the year round. The company long-term pursues the principle of quality first, customer first, quality for survival, reputation for development, and perfect service to win the users.
Weathering steel generally adopts the process route of fine material into the furnace-smelting (converter, electric furnace-microalloying treatment-argon blowing-LF refining-low superheat continuous casting (feeding rare earth wire)-controlled rolling and cooling. The scrap steel is added into the furnace together with the charge, and smelted according to the conventional process. After the ABS E40 hull structural steel steel is tapped, deoxidizers and alloys are added. After the molten steel is treated with argon blowing, the molten steel is cast. By adding rare earth elements to the steel, the ABS E40 hull structural steel weathering steel is purified and the content of inclusions is greatly reduced.
The work performance of ABS E40 hull structural steel etc. steel material is mainly depended on its chemical composition, mechanical properties etc. parameters. The higher strength the steel has, the less quantity steel is needed to achieve same strong effect of the steel structure. However, the steel strength varies with the thickness. So please take steel thickness into consideration when evaluating the steel strength. For a certain steel, its strength also has something to do with the steel shape. For example, for a same steel grade, the steel strength is different for steel plates and pipes.
The after-sales service department will pay return visit to each customer by call or email, report problems found during the return visit in time, and discuss with the production and quality inspection center to propose effective solutions and follow up in a timely manner, so as to ensure the benefits each customer are fully guaranteed, and to provide customers with more value-added services.
