15CrMo is an iron-based alloy and a heat-resistant steel material. This alloy steel has good thermal strength and oxidation resistance. Its high temperature yield strength and tensile strength are higher than ordinary carbon steel, and it also has good plasticity and toughness. In addition, 15CrMo steel also has good processing properties and welding properties, and is easy to perform heat treatment and surface treatment.
The chemical composition of 15CrMo mainly includes carbon (C), silicon (Si), manganese (Mn), chromium (Cr) and molybdenum (Mo). The specific content range is: C accounts for 0.12~0.18%, Si accounts for 0.17~0.37%, Mn accounts for 0.40~0.70%, Cr accounts for 0.80~1.10%, and Mo accounts for 0.40~0.55%. The combination of these elements gives 15CrMo excellent high temperature resistance and corrosion resistance.
Regarding the delivery state of 15CrMo steel, it should be delivered in accordance with the standard regulations. It is usually delivered in a normalized and tempered or quenched and tempered state. This processing state helps ensure that the material has stable mechanical properties and high temperature resistance.
Heat treatment is an extremely effective measure to improve and modify the properties of 15CrMo alloy round steel. It plays a very important role in product reliability and economy. The heat treatment of 15CrMo alloy round steel usually includes two categories: ordinary heat treatment (annealing, normalizing, quenching, tempering) and surface heat treatment (surface quenching and chemical heat treatment).Surface heat treatment is a heat treatment method that changes the surface properties of 15CrMo alloy round steel by changing the surface structure.
15CrMo steel is a high-quality alloy structural steel. Its characteristics are mainly reflected in the following aspects.
Excellent high-temperature strength and oxidation resistance: 15CrMo has undergone special heat treatment and alloying treatment to maintain good performance in high-temperature and high-pressure environments. When used in the temperature range of 300~400℃, it has high lasting strength and creep resistance, and the maximum operating temperature can reach 540℃. This high-temperature performance makes it suitable for industrial equipment that needs to withstand high-temperature and high-pressure environments such as power equipment and petrochemicals.
Good corrosion resistance: 15CrMo steel plate has excellent resistance to sulfur corrosion and hydrogen corrosion, slow corrosion rate, and long service life. This allows it to perform well in some corrosive working environments, such as chemical industry, petroleum and other fields.
Good mechanical properties: 15CrMo has undergone strict heat treatment and alloying treatment and has excellent mechanical properties. Its strength is better than 12CrMo steel, while its toughness is also maintained at a certain level. This enables it to withstand larger loads and stresses, making it suitable for manufacturing various important mechanical parts.
Good processing performance: 15CrMo steel has good cutting processability and cold strain plasticity, can meet the needs of various processing techniques, and is easy to perform cutting, welding, forging and other operations.
