What type of steel plate is 15Mo3?
1. 15Mo3 is a European standard container plate. Implement EN10028 standard. Known as 1.5415, it has good heat resistance and pressure resistance. It is mainly used in boilers and pressure vessels in high-temperature and high-pressure environments, as well as other components that need to withstand high temperatures and high pressures.
2. Chemical composition and mechanical properties of 15Mo3:
15Mo3 chemical composition
Carbon (C): 0.12-0.20%
Silicon (Si): 0.10-0.35%
Manganese (Mn): 0.40-0.90%
Sulfur (S): maximum 0.010%
Phosphorus (P): maximum 0.035%
Chromium (Cr): 0.25-0.35%
Molybdenum (Mo): 0.25-0.35%
Nickel (Ni): Max. 0.30%
Copper (Cu): Max. 0.30%
Vanadium (V): 0.30% maximum
15Mo3 steel plate properties
Yield strength (Rp0.2): minimum 270 MPa
Tensile strength (Rm): 440-590 MPa
Elongation (A5): 22% (sampling longitudinal direction) / 20% (sampling transverse direction)
Impact toughness (KV): 31 J minimum at 20°C
3. Application of 15Mo3 steel plate:
15Mo3 is often used in high-temperature and high-pressure environments, such as parts that are subject to high temperatures and pressures in boilers and pressure vessels. It has good heat resistance and pressure resistance, and still maintains high strength and toughness under high temperature conditions. Therefore, it is widely used in petrochemical, chemical, energy, automotive and aviation fields.
4. 15Mo3 steel plate has good high temperature resistance. Its main features are as follows:
High temperature strength: 15Mo3 steel plate still maintains good mechanical strength at high temperatures, with high yield strength and tensile strength.
Oxidation resistance: 15Mo3 steel plate can stably resist oxidation in high temperature environments, reducing the risk of oxidative corrosion and ablation.
Good toughness: 15Mo3 steel plate still maintains good toughness under high temperature conditions and can withstand thermal stress and thermal shock.
Creep resistance: 15Mo3 steel plate is able to resist creep at high temperatures, which is the ability of a material to gradually deform and deform.
