Q370R Pressure Vessel Steel: Steel used to manufacture pressure vessels in petrochemical, gas separation, gas storage and transportation equipment. It is required to have sufficient strength and toughness, good welding performance and hot and cold processing performance. The commonly used steels EN S355ML steel price are mainly low-alloy high-strength steel and carbon steel. Q370R implements the domestic standard GB713-2008.

Compared with EN S355ML steel price, boiler steel plates should have the following properties: (1) High medium temperature strength: low and medium pressure boiler drums use steel with a lower yield point, high pressure boilers use steel with a high yield point. (2) Good plasticity, impact toughness, cold bending and welding performance. (3) The notch sensitivity is small, that is, the sensitivity to the stress concentration caused by the opening of the steel plate surface and the welding of the pipe head is small.

Both steelmaking and ironmaking are carried out by oxidation-reduction reaction, but there are great differences between them in reaction objects: ironmaking is to reduce iron, while EN S355ML steel price steelmaking is to remove excessive carbon and other impurities in pig iron, so there are relations and differences between them in actual operation. There are three main methods of EN S355ML steel price steelmaking: converter, electric furnace and flat furnace. The converter steelmaking process is most widely used.

our company is leading supplier of API 5CT casing pipes in China. N80 oil casing pipes enjoy high size precision, good weld toughness, EN S355ML steel price good extrusion resistance, easy quality control and low cost features. Welcome to our company to purchase EN S355ML steel price API 5CT N80 and so on casing pipes.

Safety production is the cornerstone of enterprise survival and development. The company established a safety management network, which achieved clear powers and responsibilities, clear responsibilities, effective management and control, and provided organizational guarantee for safe production. The company strictly complies with the "Environmental Protection Law", establishes an effective environmental protection emission control system and waste gas, waste water, waste solid recycling system, and makes great efforts to harden, lighten, green, and beautify the plant, and strive to build green steel enterprises.

Customer first, reputation first, high-quality and perfect after-sales service is the extension of our product value and an important guarantee for the interests of customers. The purpose of our EN S355ML steel price service quality management system is to establish and constantly improve a scientific, reasonable and efficient service quality management system, and complete the after-sales service quality guarantee work of customers fairly, accurately and timely, For our company's EN S355ML steel price customer service to establish a good, comprehensive, full service system.
