High strength hardox 400 properties size
The quality inspection department is responsible for the inspection management of raw materials and finished products, and the quality inspection and acceptance of products and raw materials. Strictly abide by the company's management system, conscientiously exercise the management power given by the company, and put an end to all ultra vires; be responsible for the inspection of all kinds of raw materials entering the company, and put forward quality problems and handling opinions.
15CrMo alloy plate is a heat-resistant steel with pearlite structure, which has high thermal strength (δb≥440MPa) and oxidation resistance at high temperatures, and has a certain resistance to hydrogen corrosion. Due to the high content of Cr, C and other alloying elements in steel, the hardening tendency of HARDOX 400 properties and 15CrMo alloy plate is obvious and the weldability is poor. After welding, local high temperature tempering treatment should be carried out. The heat treatment process of 15CrMo alloy plate is as follows: the temperature rise rate is 200°C/h, the temperature is raised to 715°C for 1 hour and 15 minutes, the temperature drop rate is 100°C/h, and the temperature is reduced to 300°C before air cooling.
Hot Rolled Plates Products TestingBBN STEEL can supply many tests and analysis done to examine them before and after the manufacturing. As the HARDOX 400 properties raw material is fetched by us the steel undergoes vacuum treatment, product analysis, additional tensile test, simulated post weld heat treatment, and impact test. After the steel is converted to steel plates they undergo the drop-weight test, hot tensile test, ultrasonic test, the practical examination through examination, and the vacuum carbon deoxidized steel."
Pipeline steel can be divided into three types: high cold, high sulfur area and submarine laying. According to the development trend, service conditions, main failure forms and failure reasons of oil and gas pipelines, it is required that the pipeline steel HARDOX 400 properties not only has good mechanical properties, but also has negative temperature resistance, corrosion resistance, seawater resistance and hsscc resistance. These pipelines with bad working environment have long lines and are not easy to maintain, so they have strict quality requirements.
The results of adopting two-level HARDOX 400 properties 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 HARDOX 400 properties 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, HARDOX 400 properties 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 HARDOX 400 properties process technology development, technology transfer and related technical consulting and technical services.
