Steel Plate Library: Chemical Composition and Mechanical Properties of P265GH Steel Plate
mechanical properties
Yield strength: ≥ 265MPa
Tensile strength: 410~530MPa (up to 530MPa when thickness ≤ 16mm)
Elongation rate: ≥ 22%
Room temperature impact energy (20 ℃): ≥ 27J, some standards require ≥ 40J
Low temperature impact energy (-20 ℃): still ≥ 27J, with a single sample not less than 75% of the average value
High temperature performance: The yield strength of 16mm thick steel plate at 400 ℃ is ≥ 150MPa, and the high-temperature creep performance is excellent
Chemical composition (wt%, in accordance with EN 10028-2 standard)
Carbon (C): ≤ 0.20%
Silicon (Si): ≤ 0.40%
Manganese (Mn): 0.80%~1.40%
Phosphorus (P): ≤ 0.025%
Sulfur (S): ≤ 0.010% (high-end demand can be controlled within ≤ 0.005%)
Chromium (Cr): ≤ 0.30%
Nickel (Ni): ≤ 0.30%
Molybdenum (Mo): ≤ 0.08%
Vanadium (V) ≤ 0.03%, niobium (Nb) ≤ 0.02%, aluminum (Al) ≥ 0.020%, nitrogen (N) ≤ 0.012%
P265GH is a non alloy steel for pressure vessels that complies with the European standard EN 10028-2, with the numerical code 1.0425, suitable for high temperature working conditions with a working temperature of ≤ 300 ℃.
