What is 440C?
A martensitic stainless steel. It's composed of these major alloy elements (I don't list the minor elements since they don't play a major role):
Carbon: 0.95-1.25% This increases hardenability and wear resistance, but decreases toughness in higher amounts.
Manganese: 45% This is added to reduce brittleness and improve forgeability, hardenability, and reducing deformation.
Silicon: 30% This is a deoxidizer and improves hot-forming properties.
Chromium: 17.00-18.00% Added only to high alloy tool steels, this improves hardenability, high wear resistance, toughness, and corrosion resistance.
Molybdenum: 50% Improves deep hardening and toughness.
These basic elements (along with iron) are a simple combination that works well together, and has for many decades.
This alloy is technically classified as UNS (Unified Numbering System) S44044. It's also classified as SAE (Society for Automotive Engineers) as 51440C."br"The American Iron and Steel Institute classifies it as 440C martensitic standard stainless steel. Most modern knifemak
