The company adopts the international advanced management system, and has passed the certification of ISO9001 quality management system, ISO14001 environmental management system and GB / T28001-2001 occupational health and safety management system, and has realized the comprehensive integration of the three systems In the future development path, the company will adhere to the guidance of scientific development concept, accelerate the implementation of six development strategies, namely, the main business development strategy, cost leading strategy, science and technology innovation strategy, management upgrading strategy, green steel strategy, and Harmonious Co construction strategy, promote the company's sustainable development, and build the company into the most competitive modern steel group,NV D36 ore carrier steel.
NV D36 ore carrier steel,ASTM A36 is a common mild steel(carbon structure steel grade). It is widely used in morden industry owning to its cheapest rolling cost and easiest welding. , ASTM A36 mild steel is equivalent to grade Q235B under Chinese steel standard, grade S235JR under European steel standard EN 10025-2, grade SS400 in Japanese steel standard These mild steel plates and sections are commonly bolted and riveted in structural applications,NV D36 ore carrier steel.
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, NV D36 ore carrier 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.
Medium and high carbon alloy hot rolled plates are mainly used in cold rolling and calendering, saw blades and tool industries The company has taken advantage of smelting, hot rolled plate and coil finishing equipment and technical advantages, and has successfully developed a batch of high-carbon and its alloy steel and medium-carbon high-alloy steel hot-rolled coils with the goal of replacing imports The iron oxide scale is delivered and trusted by high-end users,NV D36 ore carrier steel.
"ASTM A516 Grade 70 plate is a boiler / pressure vessel quality of steel plate for use in low to moderate services. It has improved notch toughness. A516 Grade 70 steel plates can be produced with thick up to 200mm.For boiler steel plate A516 Grade 70, the yield strength shall be above 260 Mpa, tensile strength from 485 Mpa to 620 Mpa.A516 Garde70 steel plate is equivalent to the P355GH and 490B grades. "NV D36 ore carrier steel
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,NV D36 ore carrier steel.
