Material Overview

P245GH is a non-alloy quality steel primarily designed for pressure applications in elevated temperature service, including boilers, pressure vessels, and piping systems. This material is specified under EN 10028-2 and is widely utilized throughout Europe for its reliable performance characteristics.

Chemical Composition

The chemical composition of P245GH is strictly controlled to ensure optimal strength, weldability, and resistance to high-temperature service conditions. Typical composition limits (by weight percentage):

Element Content (%)
Carbon (C) ≤ 0.20
Silicon (Si) ≤ 0.40
Manganese (Mn) 0.40 – 1.40
Phosphorus (P) ≤ 0.025
Sulfur (S) ≤ 0.020
Nitrogen (N) ≤ 0.012
Residual/Trace Elements

Maximum typical values for residual elements:

Element Content (%)
Chromium (Cr) ≤ 0.30
Nickel (Ni) ≤ 0.30
Copper (Cu) ≤ 0.30
Molybdenum (Mo) ≤ 0.08
Vanadium (V) ≤ 0.02
Niobium (Nb) ≤ 0.02
Titanium (Ti) ≤ 0.03
Composition Significance
  • Moderate Carbon (≤ 0.20%): Maintains weldability while reducing cracking risk, providing sufficient strength for pressure applications
  • Manganese (0.40–1.40%): Enhances strength and toughness while aiding in steel deoxidation during production
  • Low Phosphorus and Sulfur: Minimizes impurities that can cause brittleness at elevated temperatures, improving overall toughness and reliability
  • Low Alloying and Residual Elements: Preserves non-alloy classification while slightly improving strength and high-temperature performance, maintaining excellent machinability and weldability
Important Note: For pressure equipment design and certification, always verify exact composition limits in the current EN 10028-2 standard and review the mill test certificate (MTC) from your steel supplier. Different product forms (plate, pipe, etc.) and thickness ranges may have adjusted limits within the standard specifications.
