Steels, General Properties
Categories:	Metal
Material Notes:	Steel compositions vary widely. Steels in general have a lower carbon content than cast irons, and lower amounts of impurities like phosphorus and sulfur. The composition chart above represents typical ranges for basic steel constituents. Other alloying elements such as Boron, Chromium, Cobalt, Columbium (Niobium), Copper, Molybdenum, Nickel, Nitrogen, Selenium, Tantalum, Titanium, Tungsten, and Vanadium are added to improve corrosion, high temperature, and mechanical properties of steel. The properties listed below reflect typical properties for Steels. In general, properties such as density, thermal conductivity, and electrical resistivity do not vary greatly with composition or heat treatment, whereas properties such as tensile strength, elongation, and hardness are highly dependent on composition and heat treatment.

Available Properties

Density, Density usually ranges from 7.8 - 7.9 g/cc for carbon and low alloy steels. Stainless steels typically have densities around 8 g/cc.
Hardness, Brinell, Varies widely with composition and heat treatment.
Hardness, Knoop, Varies widely with composition and heat treatment.
Hardness, Vickers, Varies widely with composition and heat treatment.
Tensile Strength, Ultimate, This is the value for AISI 1020, a mild steel. Values can range from 295 - 2400 MPa, depending on composition and heat treatment.
Tensile Strength, Yield, AISI 1020 Steel. Yield strength varies as Ultimate Tensile Strength values, from 200 - 2100 MPa.
Elongation at Break, AISI 1020. Generally as hardness and tensile strength goes up, elongation goes down.
