What alloy is 07Cr15Ni7Mo2Al?
07CR15Ni7MO2AL stainless steel is a high-performance stainless steel material with excellent corrosion resistance and high temperature strength, which is widely used in marine engineering, petrochemical, aerospace and other fields.
In this article, Shanghai Bohu will introduce the characteristics of 07Cr15Ni7Mo2AL stainless steel.
1. Chemical composition.
07Cr15Ni7Mo2AL stainless steel is a stainless steel material that contains elements such as chromium, nickel, molybdenum, and aluminum. Among them, the content of chromium accounts for more than 15% of the total alloy, which makes 07Cr15Ni7Mo2Al stainless steel have good corrosion resistance in oxidizing media. At the same time, the addition of nickel improves the toughness, high temperature resistance and stress corrosion resistance of the material. The content of molybdenum element accounts for more than 2% of the total alloy, which helps to improve the corrosion resistance and fatigue resistance of the material. The addition of aluminium can refine the grains and improve the strength and toughness of the material.
Second, mechanical properties one person and one sentence cheer for the postgraduate entrance examination
07Cr15Ni7Mo2Al stainless steel has good mechanical properties. At room temperature, its tensile strength can reach more than 800MPa, the yield strength is about 550MPa, and the elongation is more than 30%. At high temperatures, its strength and hardness can still maintain a high level, with a tensile strength of more than 600MPa and a yield strength of about 400MPa. In addition, 07Cr15Ni7Mo2Al stainless steel also has a low elastic modulus and excellent fatigue resistance.
3. Process performance.
The process performance of 07Cr15Ni7Mo2Al stainless steel is relatively good. First of all, the material is easy to cold and hot work, and can be stamped, bent, rolled, and other operations. In the process of hot processing, 07Cr15Ni7Mo2Al stainless steel has good plasticity and welding properties, and can be welded by various welding methods such as fusion welding and pressure welding. In addition, the material has good comprehensive performance after heat treatment, such as increasing hardness and toughness.
Fourth, the field of application.
Because 07Cr15Ni7Mo2Al stainless steel has excellent corrosion resistance and high temperature strength, it is widely used in marine engineering, petrochemical, aerospace and other fields. In the field of offshore engineering, the material can be used to make equipment such as facilities, ships, and subsea pipelines in offshore oil and gas fields. In the petrochemical industry, 07Cr15Ni7Mo2Al stainless steel can be used to manufacture equipment such as high-pressure reactors, pipelines and valves. In the aerospace sector, the material is used to make equipment such as aircraft parts, rocket engine parts, and space probes.
Shanghai Bohu 07CR15NI7MO2AL stainless steel is a high-performance stainless steel material with excellent corrosion resistance and high temperature strength. Its chemical composition, mechanical properties, process properties and application fields make it one of the important materials in the fields of marine engineering, petrochemical industry, aerospace and other fields.
