Working with X46Cr13 H+T200
Is X46Cr13 easy to machine?
Machine in the annealed state with sharp, rigid setups, positive-rake carbide and generous coolant; above ~45 HRC switch to grinding, EDM or CBN.
Can X46Cr13 be welded?
Poor weldability — preheat 200–300 °C, use 410/309 or matching filler, and temper immediately after welding to avoid martensitic cracking.
Can X46Cr13 be formed, bent or molded?
Only light cold forming/blanking in the annealed condition; hot work 1100–850 °C then slow cool, and always harden from 1020–1050 °C with a 150–250 °C temper.
What surface finishes work on X46Cr13?
Takes a mirror polish when hardened; passivate (nitric or citric per ASTM A967) after machining, and consider PVD/hard-chrome for extra wear or corrosion service.

X46Cr13 H+T200 — frequently asked
What is X46Cr13 H+T200 used for?
X46Cr13 H+T200 is typically used for knife blades, scissors, razors and surgical tools. In short: standard cutlery blade grade; hardest 13 % Cr stainless; wear over weldability.
What is the yield strength of X46Cr13 H+T200?
X46Cr13 H+T200 has a typical yield strength of 1,450 MPa (210 ksi) and a tensile strength of 1,750 MPa (254 ksi) — stronger than 99% of stainless steel grades. Strength varies by condition: see the 6 listed tempers.
Is X46Cr13 H+T200 easy to machine?
Not especially — machinability is rated poor (15/100, worse than 100% of stainless steel grades). Machine in the annealed state with sharp, rigid setups, positive-rake carbide and generous coolant; above ~45 HRC switch to grinding, EDM or CBN.
Can X46Cr13 H+T200 be welded?
Not readily — weldability is rated not recommended (10/100). Poor weldability — preheat 200–300 °C, use 410/309 or matching filler, and temper immediately after welding to avoid martensitic cracking.
What surface finishes work on X46Cr13 H+T200?
Takes a mirror polish when hardened; passivate (nitric or citric per ASTM A967) after machining, and consider PVD/hard-chrome for extra wear or corrosion service.
Can X46Cr13 H+T200 be formed, bent or molded?
Only light cold forming/blanking in the annealed condition; hot work 1100–850 °C then slow cool, and always harden from 1020–1050 °C with a 150–250 °C temper.
What is the maximum service temperature of X46Cr13 H+T200?
X46Cr13 H+T200 is rated for continuous use to about 200°C (392 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
