What is mechanical properties of steel S355J0WP equivalent IS standard grade

Our company attaches great importance to technical support and after-sales service, and has established a customer service center to provide unified technical support and service for mechanical properties of steel S355J0WP various engineering projects. Customer service center has a strong technical force of technical service team, composed of a customer service center manager, several mechanical properties of steel S355J0WP after-sales service personnel, responsible for unified acceptance and processing of local after-sales service needs.

At present, the company has successfully developed and produced more than 10 kinds of boron-containing steel varieties such as 35MnBM, 23MnBM, mechanical properties of steel S355J0WP, 27MnTiB, 40MnB, 25CrMoTi, etc. According to the practice of Laiwu Steel's 50t electric arc furnace-50t LF-60t VD-R11 Lianzhuo-VD Royal alloying process development and production of boron-containing steel, the technical measures for precise control of the smelting of boron-containing steel are analyzed and discussed.

mechanical properties of steel S355J0WP, S355JR is a European standard low alloy high strength structural steel, which is in accordance with EN10025-2. The hardness of S355JR steel is 70-80B, and the yield strength of S355JR steel is 355MPa. JR stands for quality level, equivalent to level B in ChinaChemical composition of S355JR steel: C: < 0.22; Si: < 0.55; Mn: < 1.60; P: < 0.025; S: < 0.025S355JR steel is equivalent to Q345B in China.

The boiler steel is not only required to have good corrosion resistance at low temperature, but also required to have good oxidation resistance at high temperature for components working at high temperature. Especially for the components of superheater and reheater, when they mechanical properties of steel S355J0WP work at high temperature, they are required not easy to be oxidized and peeled. Generally, the development speed of oxidation depth at working temperature is required to be less than 0.1mm/year. The addition of chromium, nickel, aluminum and silicon can improve the oxidation resistance of steel.

The results of adopting two-level mechanical properties of steel S355J0WP service system and implementing standardized management are mainly reflected in the formation of vigorous work style such as quick response and quick action. Our company's customer service center stipulates that employees must be accurate and quick in technical support and mechanical properties of steel S355J0WP after-sales service. Through the formation of this fast, agile, vigorous style, to provide users with satisfactory service.

It is a modern high-tech professional enterprise integrating scientific research, mechanical properties of steel S355J0WP production and sales. The company is mainly engaged in the manufacture, installation and commissioning of boiler and pressure vessel, chemical, metallurgical, petroleum and other equipment, as well as mechanical properties of steel S355J0WP process technology development, technology transfer and related technical consulting and technical services.
