What is 1.4110 +C?
1.4110 +C is 1.4110 supplied in the +C condition — choose for close-tolerance bar and knife strip where extra straightness/flatness and a harder blanking stock are wanted before hardening. 1.4110 +C has a yield strength of 700 MPa (102 ksi) and a tensile strength of 900 MPa (131 ksi) — stronger than 92% of stainless steel grades. Elongation at break is 10% and the elastic modulus is 215 GPa (31.2 Msi). 1.4110 +C has a density of 7.7 g/cm³ (0.278 lb/in³), lighter than 83% of stainless steel grades. It melts at 1,420°C (2,588 °F). +A is the default condition FabDigit quotes; +C is available on request or by drawing note.

Working with 1.4110 +C
Is 1.4110 easy to machine?
Machine in the annealed state with sharp, rigid setups, low speeds and positive-rake carbide (or ground HSS) plus generous coolant; once hardened above ~50 HRC only grinding, EDM or CBN turning is practical.
Can 1.4110 be welded?
Poor weldability — high carbon gives hard, crack-prone martensite: preheat 200–300 °C, use matching or austenitic 309/312 filler, and temper/anneal immediately after welding; fusion joining is generally avoided.
Can 1.4110 be formed, bent or molded?
Blank and bend only in the soft-annealed condition with large radii; hot work 1100–850 °C followed by slow cooling and a full soft anneal at 750–800 °C.
What surface finishes work on 1.4110?
Grind and polish to a fine finish, then passivate (nitric or citric per ASTM A967) to restore the chromium oxide film; PVD (TiN/DLC) or hard chrome can be applied if bath temperature stays below the tempering temperature.

1.4110 +C — frequently asked
What is 1.4110 +C used for?
1.4110 +C is typically used for cutlery, surgical instruments and bearings. In short: 440A-type stainless tool steel; mo-improved corrosion for blades; hardenable, effectively unweldable.
What is the yield strength of 1.4110 +C?
1.4110 +C has a typical yield strength of 700 MPa (102 ksi) and a tensile strength of 900 MPa (131 ksi) — stronger than 92% of stainless steel grades. Strength varies by condition: see the 5 listed tempers.
Is 1.4110 +C easy to machine?
Not especially — machinability is rated fair (38/100, better than 63% of stainless steel grades). Machine in the annealed state with sharp, rigid setups, low speeds and positive-rake carbide (or ground HSS) plus generous coolant; once hardened above ~50 HRC only grinding, EDM or CBN turning is practical.
Can 1.4110 +C be welded?
Not readily — weldability is rated poor (18/100). Poor weldability — high carbon gives hard, crack-prone martensite: preheat 200–300 °C, use matching or austenitic 309/312 filler, and temper/anneal immediately after welding; fusion joining is generally avoided.
What surface finishes work on 1.4110 +C?
Grind and polish to a fine finish, then passivate (nitric or citric per ASTM A967) to restore the chromium oxide film; PVD (TiN/DLC) or hard chrome can be applied if bath temperature stays below the tempering temperature.
Can 1.4110 +C be formed, bent or molded?
Blank and bend only in the soft-annealed condition with large radii; hot work 1100–850 °C followed by slow cooling and a full soft anneal at 750–800 °C.
What is the maximum service temperature of 1.4110 +C?
1.4110 +C is rated for continuous use to about 400°C (752 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
