Home > Blossary: Types of Steels
Steel is an alloy of iron, with carbon being the primary alloying element, up to 2.1% by weight. Carbon, other elements, and inclusions within iron act as hardening agents that prevent the movement of dislocations that naturally exist in the iron atom crystal lattices.

Martensitic stainless steels make up the cutlery grades. They have the least amount of chromium, offer high hardenability, and require both pre- and postheating when welding to prevent cracking in ...

For the most part, we're talking about stainless steel here, the most important commercial high-alloy steel. Stainless steels are at least 12 percent chromium and many have high nickel contents. ...

Their carbon content is usually below 0.25 percent and often below 0.15 percent. Typical alloys include nickel, chromium, molybdenum, manganese, and silicon, which add strength at room temperatures ...

Composition of 0.96%-2.1% carbon. Its high carbon content makes it an extremely strong material, though it is brittle and requires special handling.

Domain: Materials science; Engineering; Education; Category: Metallurgy; Mechanical engineering; Knowledge

Composition of 0.55%-0.95% carbon with 0.30%-0.90% manganese. It is very strong and holds shape memory well, making it ideal for springs and wire.

Domain: Materials science; Engineering; Education; Category: Metallurgy; Mechanical engineering; Knowledge

Composition of 0.29%-0.54% carbon with 0.60%-1.65% manganese. Medium carbon steel is ductile and strong with good wear properties.
