Product introduction of Chongqing Iron and Steel (Group) Co., Ltd.

Chongqing Iron and Steel Co., Ltd. is the earliest manufacturer in China to produce pressure vessel steel plates from low temperature, normal temperature, medium temperature to high temperature, and its product quality is stable, which is at the leading level in China. "Sanfeng" brand steel plate produced by Chongqing Iron and Steel Co., Ltd. has always had product quality and brand advantages, and has been praised as "the first plate in China" by the industry. The quality of 16MnR pressure vessel steel plate and 20g boiler steel plate produced by the company has reached the international advanced level, and won the National Quality Gold Award and the Gold Cup Award of the former Ministry of Metallurgy. It is the first user-free steel product in China approved by the boiler and pressure vessel safety supervision bureau of the Ministry of Labor. In 2006, the steel plate for boiler and pressure vessel produced by Chongqing Iron and Steel Co., Ltd. won the title of "China Famous Brand Product". Nearly 30 large-scale pressure vessel manufacturers in China use steel plates for low-temperature pressure vessels produced by Chongqing Iron and Steel Co., Ltd. to manufacture low-temperature pressure vessels according to American ASTM standards, and have obtained the accreditation certificate and steel seal mark of American Society of Mechanical Engineers (ASME). The product is pure steel, uniform and fine structure, excellent comprehensive performance, stable quality characteristic value and large quantity, and has been delivered to Class I or Class II through flaw detection. With the environmental protection relocation of Chongqing Iron and Steel Co., Ltd., new steel purification facilities and the most advanced quality control means are more perfect. The physical quality of this product has been steadily improved, and it can be supplied in a wider range, which is deeply loved by users. It has been widely used to manufacture I, II and III pressure vessels and various pressure vessel reaction tanks, heat exchangers, separators, storage and transportation devices, corrosion-resistant vessels and multi-layer high-pressure vessel cylinders.

On August 5th, 20 1 1, Chongqing Iron and Steel Co., Ltd. passed the expert appraisal successfully. So far, Chongqing Iron and Steel Co., Ltd. has been qualified to produce steel plates for boilers and pressure vessels with a maximum thickness of 80mm, and Chongqing Iron and Steel Co., Ltd. continues to be at the leading level in China in this special steel production field. Chongqing Iron and Steel Co., Ltd. is one of the main research and development bases of low-alloy high-strength steel in China. Q345 series steel plates produced by Chongqing Iron and Steel Co., Ltd. according to GB/T 159 1-94 have stable quality and large residual value of performance indexes, which are widely used in mining machinery, construction machinery and heavy-duty automobile manufacturing. In recent years, modern steel purification facilities and advanced quality control methods have been improved. Steel rolling can produce σ S 390-685 MPa series products according to controlled rolling, controlled cooling, normalizing and quenching and tempering. The product has stable quality, good wear resistance and good low temperature toughness. It can be widely used in the manufacture of mining machinery, construction machinery, high-rise buildings and heavy vehicles.
