Corrosion resistance of 30MnB5 boric steel steel
We received new order from Myanmar's Navy. It is about 30MnB5 boric steel AH36 marine grade steel plates, which will be used to build ships. This is the third time we supplied marine grade steel materials for Myanmar's Navy. This time a new delegation team came to visit us and spoke highly about our production lines and our marine grade steel plates performance supplied 30MnB5 boric steel to Myanmar's Navy before. Both of us expects a pleasant cooperation.
The company has five major departments: steel plate production department (including quality inspection team), sales department, market development department, after-sales and logistics department, and finance department. The backbone of steel business from all over the country, with the chairman as the core, integrates self-confidence, independence, passion and responsibility, and strives for excellence! All people share the same belief: "Being a refined steel product line rewards customers, strengthen the steel industry, and realize the corporate dream!
Weathering steel has good resistance to atmospheric corrosion. Although the initial investment cost of weathering steel is slightly higher than that of ordinary carbon steel. Compared with methods such as spraying anticorrosive coating on the surface of ordinary carbon steel, the later maintenance costs of ordinary carbon steel are weathering steel. 1.5-2 times. Therefore, 30MnB5 boric steel weathering steel can reduce environmental pollution and is a key promotion technology for energy saving and emission reduction. Most domestic weathering steels are painted and used, and their original intentions of no-painting and "rust prevention" have not been exerted to a greater extent.
The main competitive means adopted by major domestic ports are to expand ports, build deep-water berths and channels, improve service quality to reduce the comprehensive cost of customers, and at the same time, to improve competitive advantage, we should also take appropriate measures to reduce relevant costs and prices.
Chromium element (Cr element) can improve the strength and hardness of 30MnB5 boric steel, carbon steel in rolling state, reduce elongation and area reduction. When the chromium content is more than 15%, the strength and hardness will decrease, while the elongation and reduction of area will increase correspondingly. It is easy to obtain high surface processing quality for steel parts containing chromium after grinding. The main function of chromium element (Cr element) in quenched and tempered steel structure is to improve hardenability, so that the steel has better comprehensive mechanical properties after quenching and tempering.
If you have steel demands in the near future, please send us inquiry in advance, as we have regular steel production plan and can arrange you a reasonable prodction time. Other than fresh production, we also have huge 30MnB5 boric steel stocks for the most widely used steel materials. So that the customers need not wait too long to get their required steel. Welcome to contact us and consult steel price, our sales person will give you professional answers and suggestions.
After-sales service team is a key department to test the steel quality. Product quality is always the foundation of our survival and development. The company's full inspection from raw materials to finished products; and implements standardized, scientific, and strict internal quality control and management systems in accordance with the process flow during the production process; products can only leave the factory if qualified, and follow-up problem solving systems are implemented in after-sales services to guarantee the customers’ interest.
