Metals For Making Knives

Use Of 304l, 316l, And 51670 For Knives?

Several steel alloys have carbon quantity close or above three%. As traditional these steels can be hardened to extremely excessive levels, sixty five-67HRC. CTS-XHP, a powder metallurgy, air-hardening, high carbon, excessive chromium, corrosion-resistant alloy.

Different Types Of Stainless Steel

Chromium, molybdenum, vanadium, and tungsten are added for excellent sharpness and edge retention. Hardens and tempers to HRC, where it best balances edge holding and toughness.

316l stainless steel for knife making

  • The added benefit of using stainless steel is addition of chromium and different alloying elements that enhance corrosion resistance.
  • Stainless metal is one other type of knife-making metallic.
  • In order to make knives which have first rate edge retention, the martensitic and ferritic grades of chrome steel have to have a high enough carbon levels to be able to reach excessive hardness.
  • Grades such as 420 and 440 are regularly used for knife making.
  • Stainless steel knives are usually made out of ferritic or martensitic stainless steels.

Elmax is similar to M390, CPM 20CV, and CTS 204P, however has considerably decrease Vanadium content, and lacks any Tungsten content. A grade with good put on resistance and good corrosion resistance, nicely fitted to the manufacture of kitchen tools. Sandvik series6C27, a typical knife steel grade with good corrosion resistance and low hardness, mainly used in applications where the necessity for put on resistance is low.

This grade of stainless holds a great edge however may be tough to sharpen due to its high hardness. ATS-34 has good corrosion resistance, although not as excessive as the 400 series knife metal. These grades of Japanese stainless are corresponding to 440A (AUS-6), 440B (AUS-eight), and 44C (AUS-10). It holds a good edge and is pretty easy to resharpen.

With a great heat treat, the high carbon 1095 and O-1 tool steels can make wonderful knives. LC200N (aka Z-FiNit) produced by Zapp Precision Metals, is a high nitrogen alloyed device steel which exhibits superior corrosion resistance mixed with excessive toughness even at hardness up to 60 HRc. Spyderco makes use of this metal in several of their knives.
