What is 13CrMoV9-10?
13CrMoV9-10 (1.7703) is a low-carbon creep-resisting Cr-Mo-V steel from the EN 10083 group, related to 12Cr1MoV and ASTM A213 T24, in which vanadium carbides stabilise strength at elevated temperature. Typical properties are 500 MPa yield, 680 MPa tensile, 20% elongation, about 215 HB (18 HRC) and 35 W/m·K thermal conductivity, with service to 570 °C; it is supplied as seamless tube, plate, forged flanges and valve bodies. It has essentially no corrosion resistance and requires controlled preheat plus mandatory 690-720 °C PWHT. For lower service temperatures, 13CrMo4-5 or 10CrMo9-10 are simpler alternatives. 13CrMoV9-10 has a density of 7.85 g/cm³ (0.284 lb/in³), heavier than 56% of steel grades. It melts at 1,450°C (2,642 °F). 13CrMoV9-10 has a yield strength of 500 MPa (72.5 ksi) and a tensile strength of 680 MPa (98.6 ksi) — stronger than 63% of steel grades. Elongation at break is 20% and the elastic modulus is 210 GPa (30.5 Msi).

Working with 13CrMoV9-10
Is 13CrMoV9-10 easy to machine?
Machine in the annealed or as-tempered condition with rigid setups, coated carbide, moderate speed and heavy positive feed; the V-rich bainite work-hardens and abrades tooling faster than plain 4130/4140.
Can 13CrMoV9-10 be welded?
Weld with matching low-Si 2.25Cr-1Mo-V filler (e.g. E9018-G / B3V, SAW with basic flux), preheat/interpass 200–250 °C, strict hydrogen control, and mandatory PWHT at 690–720 °C; watch for reheat cracking in coarse HAZ and step-cooling embrittlement limits (J and X factors).
Can 13CrMoV9-10 be formed, bent or molded?
Hot form at 1050–900 °C and re-heat-treat afterwards; cold bending is limited by the high yield strength and should be followed by stress relief.

13CrMoV9-10 — frequently asked
What is 13CrMoV9-10 used for?
13CrMoV9-10 is typically used for boiler tubes, steam pipelines, turbine casings and power-plant flanges. In short: creep strength to 570 °C; weldable Cr-Mo-V pipe steel.
What is the yield strength of 13CrMoV9-10?
13CrMoV9-10 has a typical yield strength of 500 MPa (72.5 ksi) and a tensile strength of 680 MPa (98.6 ksi) — stronger than 63% of steel grades. Strength varies by condition: see the 5 listed tempers.
Is 13CrMoV9-10 easy to machine?
Not especially — machinability is rated fair (42/100, worse than 73% of steel grades). Machine in the annealed or as-tempered condition with rigid setups, coated carbide, moderate speed and heavy positive feed; the V-rich bainite work-hardens and abrades tooling faster than plain 4130/4140.

With care — weldability is rated fair (45/100). Weld with matching low-Si 2.25Cr-1Mo-V filler (e.g. E9018-G / B3V, SAW with basic flux), preheat/interpass 200–250 °C, strict hydrogen control, and mandatory PWHT at 690–720 °C; watch for reheat cracking in coarse HAZ and step-cooling embrittlement limits (J and X factors).
What surface finishes work on 13CrMoV9-10?
No anodizing; use shot blast plus high-temperature aluminum/silicone paint externally, or 347/309L stainless weld-overlay or explosion-clad lining for corrosive process sides.

What is the maximum service temperature of 13CrMoV9-10?
13CrMoV9-10 is rated for continuous use to about 570°C (1,058 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
How much does 13CrMoV9-10 cost?
13CrMoV9-10 is a standard-cost steel ($$), cheaper than about 71% of the materials FabDigit quotes. Part price depends far more on geometry, tolerance and quantity than on the raw stock — upload a CAD file for a live quote.
