1.4923 / X22CrMoV12-1 Forging Material | China Professional Forged Parts Manufacturer

What is 1.4923 / X22CrMoV12-1 Forging Steel?

1.4923 (standard EN designation: X22CrMoV12-1, also known as X22CrMoV12.1, X22CrMoV121) is a martensitic chromium-molybdenum-vanadium heat-resistant alloy steel, and it is used for long-term service in high-temperature, high-pressure environments up to 600°C.

This material has excellent mechanical properties, so that it is normally recognized as the industry standard for critical steam and gas turbine parts.

• Outstanding creep rupture strength and fatigue resistance at continuous operating temperatures up to 600°C
• Excellent oxidation and scaling resistance in superheated steam and high-pressure gas environments
• Excellent steam corrosion resistance for power plant valve and turbine applications
• High tensile strength and structural stability under cyclic thermal and mechanical loading
• Excellent hardenability and consistent tempered martensite microstructure after quenching and tempering

While its corrosion resistance in natural atmospheric environments is moderate due to its  chromium content of 11.0-12.5%, 1.4923 steel  has great performance in high-temperature steam and industrial gas environments, which makes it the best choice material for critical rotating and pressure components in power generation systems.

Manufacturing Process & Heat Treatment Specification for 1.4923 Forgings

As a professional China 1.4923 forging manufacturer, we have the full production process to make sure all parts have consistent quality, great mechanical properties, and long lifetimes.

Melting & Forging Process

• Melting Process: Standard production uses Electric Arc Furnace (EAF) + Ladle Refining (LF) + Vacuum Degassing (VD/VOD). For extreme aerospace and turbine applications, we offer Electroslag Remelting (ESR) to make sure the highest material purity and homogeneity, with non-metallic inclusion control per ASTM E45.
• Forging Process: Preheating to 850°C before rapid heating to 1150-1180°C for forging, with a forging temperature range of 950-1180°C.
  We keep a minimum forging reduction ratio of 4:1 (up to 8:1 for critical parts) to remove casting flaws. For turbine blades, we apply strict forging flow line control to maximize fatigue resistance.
• Post-Forging Cooling: Controlled slow cooling in a furnace or dry ash to avoid thermal stress and cracking, with full temperature tracking throughout the process.

Standard Heat Treatment Specification

To get the required mechanical properties and microstructure, we use quenching and tempering process for 1.4923 / X22CrMoV12-1 material:

1. Austenitizing: Holding the material at 1020-1070°C, followed by quenching in air, oil, or polymer quenchant to achieve full martensitic transformation
2. Tempering: Tempering at a minimum temperature of 650°C (range 640-740°C), with sufficient holding time to ensure uniform microstructure, followed by controlled air cooling
3. Stress Relieving: For straightened components, we perform stress relieving at 30°C below the actual tempering temperature, with a slow cooling rate to minimize residual stress and avoid distortion during machining
4. Full Documentation: Complete heat treatment cycle charts and records are included in the mill test certificate for every batch

Our heat treatment process gets a consistent internal grain distribution, with delta ferrite content controlled below 5% (below 1% for aerospace and turbine blade applications), and grain size of 4 or finer per ASTM E 112.
