-81.71%410 stainless steel (UNS S41000, ASTM A276 / A240) is a martensitic stainless steel with 11.5–13.5% chromium that hardens by quenching and tempering. It is bought annealed, machined and, if the drawing calls for it, hardened for hardness and wear resistance. It is magnetic. At PREMSA we CNC turn and mill it from your file: valve seats and valve parts, shafts, bushings, pump parts and wear parts, starting at a single part with an instant price.
Engineering-grade properties of 410 stainless steel, including mechanical, physical, and heat treatment characteristics relevant to hardened components and wear-resistant applications. This data supports material selection where strength and hardness are critical.
Alloy Type
Martensitic stainless steel (12% chromium)
Primary Characteristics
Hardens by quenching and tempering, good wear resistance, moderate corrosion resistance, magnetic
Tensile Strength (Ultimate)
Annealed: 515 MPa (75 ksi) min · Hardened and tempered: 690–1,300 MPa (100–190 ksi) depending on temper
Tensile Strength (Yield)
Annealed: 275 MPa (40 ksi) min · Hardened and tempered: 550–1,000 MPa (80–145 ksi)
Elongation at Break
Annealed: 20% min · Hardened and tempered: 12–15%
Hardness
Annealed: 96 HRB (217 HB) max · Hardened and tempered: up to 45 HRC
Density
7.75 g/cm³ (0.280 lb/in³)
Elastic Modulus
29,000 ksi (200 GPa)
Poisson’s Ratio
0.27
Thermal Conductivity
24.9 W/m·K
Coefficient of Thermal Expansion
9.9–10.4 µm/m·°C
Melting Range
1480–1530 °C (2700–2790 °F)
Machinability
Good when annealed; hardened it machines more slowly, with carbide tooling
Formability
Moderate when annealed
Weldability
Limited: needs preheating to 150–260 °C and tempering after welding
Corrosion Resistance
Moderate: withstands dry air, fresh water, steam and mild acids; hardened and polished it protects better; it rusts with chlorides
Heat Treatment
Hardened from 925–1,010 °C in oil or air and tempered; tempering between 400 and 565 °C is avoided (it lowers toughness)
Common Forms
Round bar, hex bar, flat bar, plate and sheet
Typical Applications
Valve seats and valve parts, shafts, bushings, pump parts, fasteners, wear parts, tooling
Material Composition
Chromium 11.5–13.5%, carbon 0.08–0.15%, manganese 1.00% max, silicon 1.00% max, nickel 0.75% max, phosphorus 0.040% max, sulfur 0.030% max, balance iron

Custom 410 parts
What people ask most about 410 stainless steel parts: what it is, what it is used for, composition, hardness, hardening, equivalents, density, magnetism, rust, price and tolerances.
410 stainless steel is chosen for parts that have to be hardened and resist wear without rusting in moderate environments: valve seats and valve parts, shafts, bushings, pump parts and fasteners. It is bought annealed, machined and, if the drawing calls for it, hardened and tempered.
At PREMSA Industries we machine 410 with CNC turning and milling from your file, from a prototype to production.
410 is chosen when the part needs hardness and wear resistance and also has to be stainless.
If your drawing doesn’t specify tolerances, we machine to ISO 2768-m (medium). On dimensions you call out —diameters, bores, seats and fits— we can hold ±0.025 mm (±0.001 in), and critical dimensions are checked in inspection. If the part is hardened after machining, hardening moves it: tight dimensions are left with stock and ground or finished after hardening.
410 is machined with CNC turning, CNC milling, drilling and tapping, preferably annealed.
After machining, the part is hardened from 925–1,010 °C in oil or air and tempered to the hardness on the drawing: a low temper leaves the part harder, a high temper makes it tougher. We machine the part and, if you ask, send it out for hardening.
410 is welded with care.
For its hardness and because it is stainless, 410 is used in many parts made with CNC machining.
410 is usually the right choice when the part has to be hardened and can’t rust in a moderate environment.
