02Equivalent Steel Grades
P355GH is a mainstream European EN-standard heat-resistant boiler & pressure vessel steel with commonly referenced alternative grades for engineering substitution.
Standard System
Equivalent Grade
Chinese GB Standard
Q345R
American ASTM Standard
A516 Gr70
Note: Equivalent grades match P355GH in general high-temperature strength and service purpose, yet differ in chemical limits, impact and heat-treatment conditions. For pressure equipment, verify the design code and project specification before cross-standard substitution.
03Chemical Composition
Chemical composition of EN 10028-2 P355GH (ladle analysis, values in % unless noted). Strict composition control ensures good weldability and stable high-temperature strength.

P (Phosphorus, max)
0.025
S (Sulfur, max)
0.010
Note: Low phosphorus (P ≤ 0.025) and sulfur (S ≤ 0.010) combined with controlled manganese give P355GH good weldability and stable behavior at elevated temperature.
04Mechanical Properties
Mechanical properties of EN 10028-2 P355GH. Yield strength is 355 MPa with tensile strength 470–650 MPa, elongation ≥20%, and impact testing performed at +20°C, 0°C and −20°C.

Note: Yield 355 MPa is the nominal / minimum value for EN 10028-2 P355GH; the standard defines thickness-dependent yield minima (lower for thicker plates). The impact energy (KV, Charpy V-notch) requirement is verified at +20°C, 0°C and −20°C. Confirm exact limits against the Mill Test Certificate and project specification.
