Understanding the key properties and applications of 15CrMo5 Steel grade

The 15CrMo5 steel grade is a low alloy steel that is primarily used in applications requiring high temperature resistance and strength. It has good mechanical properties, excellent creep strength, and good hardenability.

In terms of mechanical properties, the 15CrMo5 steel grade has a tensile strength ranging from 580MPa to 780MPa, a yield strength of at least 450MPa, and a high elongation of more than 17%. These properties make it suitable for use in various high-stress applications, such as pressure vessels, steam boilers, and power plants.

The chemical composition of 15CrMo5 steel grade primarily consists of iron (Fe) as the base metal, with chromium (Cr) and molybdenum (Mo) as the main alloying elements. The composition typically includes 0.12-0.17% carbon (C), 0.40-0.60% manganese (Mn), 0.25-0.35% silicon (Si), 0.90-1.20% chromium (Cr), 0.15-0.30% molybdenum (Mo), and traces of other elements such as sulfur (S) and phosphorus (P).

The addition of chromium and molybdenum in the steel composition provides enhanced oxidation resistance, high temperature strength, and improved creep resistance. This makes the 15CrMo5 steel grade suitable for use in high-temperature environments, such as heat exchangers, petrochemical plants, and manufacturing equipment for the chemical industry.

Overall, the 15CrMo5 steel grade is a versatile low alloy steel with excellent mechanical properties and high-temperature resistance. Its applications range from pressure vessels and boilers to chemical plants and power generation equipment.
