What the alloying elements do
Iron
Base metal of all steels listed here and always the largest share.
Carbon
Enables high hardness and improves edge retention. A high content can make the blade more brittle.
Chromium
Improves corrosion resistance and wear resistance. A lot of chromium does not automatically mean perfect rust resistance.
Molybdenum
Improves strength, hardenability and often corrosion resistance as well.
Vanadium
Forms very hard carbides, refines the grain and increases wear resistance and edge retention.
Tungsten
Increases wear resistance and hot hardness; typical in blue steels and high-speed steels.
Cobalt
Strengthens the steel matrix and supports high hardness and long edge retention.
Nickel
Mainly increases toughness and strength and can support corrosion resistance.
Niobium
Forms very hard carbides, refines the grain and increases wear resistance and edge retention.
Copper
In small amounts can affect corrosion resistance; usually only present in small quantities in knife steel.
Manganese / Silicon
Support production and hardenability; usually present only in small amounts.
Nitrogen
Can improve hardness, microstructure stability and corrosion resistance; especially important in nitrogen-alloyed steels.
