In August 2011, the expanded license for the special equipment material manufacturing of NV D32 ore carrier steel steel plates for heavy steel boilers and pressure vessels successfully passed the expert review and identification. At this point, the company has the qualification to produce steel plates for boilers and pressure vessels with a maximum thickness of 80 mm. Production continues to be at the leading domestic level. Our boiler steel plate has been widely used in the NV D32 ore carrier steel manufacture of I, II, III pressure vessels and various pressure vessel reaction tanks.
Our company specializes in the production of steel plates, steel coil, steel sections, welded pipes and seamless pipes products, sales of GB, ASME, ASTM, JIS, DIN, EN, API and other standards and specifications of steel NV D32 ore carrier steel and deep-processed products, facing the domestic and foreign markets, welcome to call for inquiries. It is a modern high-tech professional enterprise integrating scientific research, production and sales.
The purpose of NV D32 ore carrier steel quenching is to transform the supercooled austenite into martensite or bainite to obtain a martensite or bainite structure, and then cooperate with tempering at different temperatures to greatly improve the strength, hardness, performance, fatigue strength, toughness, and wear resistance etc. of NV D32 ore carrier steel. So as to meet the different use requirements of various mechanical parts and tools. Quenching can also help to get the ferromagnetic, corrosion resistance and other special physical and chemical properties of certain special steels.
After adding a small amount of niobium, vanadium and titanium to NV D32 ore carrier steel etc. steel, it is combined with the controlled rolling process to control the precipitation behavior of microalloying elements to achieve the purpose of improving the comprehensive properties of the steel, whether it is strength, toughness, ductile-brittle transition temperature, or Steel's process formability, welding performance, corrosion resistance and crack resistance have been significantly improved, while reducing production costs. Such steel products are widely used in oil and gas pipelines, vehicles, building structures, oil production platforms, pressure vessels, ship shells and many other fields.
We should focus on the main problems to be solved and pay attention to efficiency. After receiving the user's quality objection report data, the possible causes, responsible units, compensation amount, etc. of the problem shall be judged based on experience. To have a clear service plan, to be clear about what your main problem is, what technical support is needed, these should be prepared.
