Description
9Cr18Mo Stainless Blade Steel (3.3 x 50 x 1000 mm billet)
High Carbon Stainless Steel for blades, high in Chromium for good corrosion resistance in the kitchen or marine use.
Composition:
C 0.97%, Si 0.53%, Mn 0.57%, P 0.013%, S 0.007%, Mo 0.53%, Cr 18.64%, Ni 0.33%
How to Heat Treat 9Cr18Mo or any other 440C family steel:
- Hold at 760 C for 10 mins (1400 F)
- Hold at 1040 C for 30 mins (1900 F)
- Quench can be still air, plates, or even oil (Air quenched steel so plates or oil not required)
- If possible: -70 C for 30 mins (-95 F)
- Temper at 190 C (375 F) for 2 hours, cool in tap water and temper for 2 hours again
- this will give an estimated 59-60 HRC if cryo step is included
