Specifications
Description
13CrMo4-5 PN16 Forged Flanges (1.7335 Steel)
Material Overview

13CrMo4-5 is a low-alloy heat-resistant steel commonly used for boiler, pressure vessel, and high-temperature piping applications, typically operating at temperatures up to 530–580°C depending on code requirements and design specifications.

Chemical Composition

Typical composition according to EN standards (e.g., EN 10216-2):

Element Content (wt%)
Carbon (C) 0.10 – 0.18
Silicon (Si) ≤ 0.40
Manganese (Mn) 0.40 – 0.90
Phosphorus (P) ≤ 0.025
Sulfur (S) ≤ 0.010
Chromium (Cr) 0.70 – 1.15
Molybdenum (Mo) 0.40 – 0.60
Nitrogen (N) ≤ 0.012

Iron (Fe) makes up the balance of the composition.

Alloying Elements Function
  • Chromium (~1%): Improves oxidation and corrosion resistance at elevated temperatures and contributes to strength
  • Molybdenum (~0.5%): Increases creep resistance and high-temperature strength
  • Carbon and Manganese: Help achieve required strength and hardenability
  • Low Phosphorus and Sulfur: Improve toughness and weldability
Typical Applications
  • Boiler tubes and headers
  • Steam lines and high-temperature piping
  • Pressure vessels operating at elevated temperatures
Important Note: When working to specific codes (e.g., EN 10216-2, EN 10028-2), verify the exact grade and product form requirements, as composition limits can vary slightly between standards and product types (pipes, plates, forgings).
