Hot continuous rolling can be divided into ordinary carbon structural steel, low alloy steel and alloy steel according to materials and properties. According to the different uses, it can be divided into: cold forming steel, structural steel, automobile structural steel, corrosion-resistant structural steel, mechanical structural steel, EN 10025 S460M steel supplier, welding gas cylinder and pressure vessel steel, pipeline steel, etc. We adhere to the tenet of "customer first, quality assurance and good reputation", and always provides high-quality products for our customers.
Quenching Improve the hardness of EN 10025 S460M steel supplier steel, Annealing is refine the grain size, homogenization, reduce hardness, improve the plasticity and eliminate interna stress. Normalizing refine grain , improve the impact toughness of EN 10025 S460M steel supplier steel and comprehensive mechanical properties.
A few days ago, the relevant person in charge of China National Railway Group Co., Ltd. introduced that since the 18th National Congress of the Communist Party of China, 14 concentrated contiguous poverty-stricken areas, including old and poor, have completed a total of 3.3 trillion yuan in railway infrastructure investment, accounting for 78% of the total railway infrastructure investment; 36,000 kilometers of new lines were put into operation (20,000 kilometers of high-speed rail), accounting for 83% of the new lines put into operation in the country. Up to now, the railway network and 154 trackless stations on the whole road cover about 600 national-level poverty-stricken counties, accounting for 73% of the country's 832 poverty-stricken counties.
From the name, we can clearly know that seamless pipe is seamless steel pipe, which is different from welded pipe. Seamless pipe is actually a kind of steel with hollow section. EN 10025 S460M steel supplier, Seamless pipe has many advantages, such as: 1, the compressive capacity of seamless pipe is very good, the place with high bearing strength will not crack, and its bearing capacity is very good. 2. Seamless pipe has no welding point, so it is more corrosion-resistant and can bear larger pressure.
