The strict quality control of JIS carbon steel SM520C CS plate processing

The company produces seamless steel pipes such as GB, ASTM, etc. all year round, including low and medium pressure boiler steel pipes, high pressure boiler steel pipes, JIS carbon steel SM520C CS plate seamless steel pipes for ships and petroleum cracking JIS carbon steel SM520C CS plate steel pipes, Seamless steel pipe, oil sleeve steel pipe, pipeline steel pipe, hollow sucker rod, common fluid steel pipe, structural pipe, kauden steel pipe, seawater corrosion-resistant titanium pipe and imported alloy steel pipe are used for high-pressure fertilizer equipment. The products are widely used in petroleum, chemical, electric, boiler, ship, machinery and other industries, and have been sold all over the country. Many JIS carbon steel SM520C CS plate products have been exported to the Middle East, India, Southeast Asia and Europe and America.

The effect of nitrogen on steel performance is similar to that of carbon and phosphorus. With the increase of JIS carbon steel SM520C CS plate nitrogen content, the strength of steel can be improved, plasticity especially toughness can be significantly reduced, weldability becomes worse, and cold brittleness is intensified. Nitrogen with aluminum, niobium, vanadium and other elements can reduce its adverse effects, improve the performance of JIS carbon steel SM520C CS plate steel, can be used as an alloying element of low alloy steel.

The main difference between JIS carbon steel SM520C CS plate, 45# steel plate and boiler steel plate is the difference of carbon content and impact toughness. 45# steel is a high-quality carbon structural steel, which is expressed by the number of ten thousand percent of the average carbon content. The 45# steel represents the high-quality carbon structural steel with 0.45 percent carbon content. The high-quality carbon structural steel contains less harmful impurity elements (S, P) and non-metallic inclusions, and has excellent plasticity, toughness and processing technology.

The main problem of safety education in iron and steel enterprises is not that the company does not pay attention to it and does not implement it, but that the subordinate units do not strictly follow the company's requirements. In order to avoid the problem of safety education becoming a mere formality, BBN steel company improved the safety education model from the following aspects: First, the content of safety education should not only pay attention to the accumulation of safety knowledge, but also pay attention to the mastery of safety operation skills.
