410 Stainless Steel Pipe – Heat-Treatable Martensitic Strength for Oil & Gas, Valves, Pump Shafts & High-Pressure Systems
Introduction – Why 410 Stainless Steel Pipe is the Go-To Martensitic Grade for Aggressive Service
When downstream pressure tops 10,000 psi and the Christmas tree on a remote offshore well demands a magnetic, hardenable alloy that will not buckle under torsional load, engineers specify 410 stainless steel pipe. This martensitic champion combines the lowest alloy cost in the 400-series with the unique ability to quench & temper to 38-45 HRC, giving oil & gas contractors a 410 stainless steel seamless pipe that rivals 17-4PH strength at a fraction of the price. From North Sea sub-surface safety valves to Permian Basin frac pumps, a properly heat-treated martensitic 410 stainless steel pipe resists erosion, galling and mild CO₂ environments while staying fully magnetic for NDT inspection.
Unlike austenitic 304/316, 410 stainless steel pipe hardness can be dialed from 22 HRC (annealed) to 45 HRC (quenched & tempered), delivering tensile strength up to 1,000 MPa—perfect for pump shafts, hydraulic cylinders, turbine blades and high-pressure bolts turned from ASTM A276 round bar. Budget-conscious EPCs also profit from our competitive 410 stainless steel pipe price, tight mill integration and EN 10204 3.1/3.2 certification with NACE MR0175. Whether you need schedule 40 410 stainless steel pipe or XXS seamless line pipe, we stock 10,000+ tons, ready for same-day shipment.

Heat Treatment Guide for 410 Stainless Steel Pipe
- Annealing: 750–850 °C, furnace cool to 600 °C, then air cool → softest state for machining.
- Hardening: 950–1050 °C, oil or air quench → full martensite, ~45 HRC.
- Tempering:
- 600 °C → 45 HRC, highest strength, moderate toughness
- 750 °C → 38 HRC, optimal impact resistance for valve stems
All treatments must be performed after welding to restore 410 stainless steel heat treatment pipe properties.
