Case hardening of steel is used for numerous applications including for the manufacture of carbon steel forgings and carbon steel pinions. Alloy steels are normally case hardened to increase the metal characteristics. The outer layer of case hardening steel becomes hard, while the inner core remains soft and workable. Oct 07, 2019 · Once the steel’s been heated for 3 hours, let the steel cool slowly. This allows the steel to normalize and keep its hardened structure. Take the steel out of the oven the following morning. If you tempered the steel with a blow torch, set the metal on an anvil or another large steel surface to conduct the heat.
A2 Tool Steel. A2 Tool Steel is a versatile, air-hardening tool steel that is characterized by good toughness and excellent dimensional stability in heat treatment.A2 is intermediate in wear resistance between O1 oil-hardening tool steel and D2 high-carbon, high-chromium tool steel.

May 25, 2017 · Care must be taken to ensure that a carbon steel blade does not rust. Common grades of carbon steel for knife making include C1045, C1075, and C1090. Stainless Steel. Stainless steel is another type of knife-making metal. The added benefit of using stainless steel is addition of chromium and other alloying elements that increase corrosion ...
410 stainless is a corrosion and heat resistant 12% chromium steel. It is the most widely used of the hardenable stainless steels. Heat treated 410 has mechanical properties comparable to the engineering alloy steel AISI 4130, coupled with the additional benefit of good corrosion resistance. 410 is highly resistant to atmospheric corrosion.
