For instance, 1018 mild steel is simply iron with a carbon content of 0.18%. You can determine the alloying ingredients by the first two digits of the alloy number, and the carbon content by the last two digits. The numbering system for steel is actually one of the few things in the metals industry that seems to make sense. Steel does, of course, have poor corrosion resistance, but its relatively low cost and ease of painting make it a common choice. If there is something that needs to be made, there probably is a steel alloy that it can be made of. The old definition of steel used to be something like “it rusts and it sinks in water.” This material comprises the most diverse group of alloys and applications in the metals world. Steel is a term used for iron to which between 0.02 to 1.7% carbon has been added. Stainless Steels - Identification Tests - Magnetic, spark, hardness and acid identification tests for austenitic, martensitic and ferritic stainless steels.Structural Carbon Steel | Structural Alloy Steel | Spring Steel | Rolling Bearing Steel | Free-machining Steel | Anti-friction Steel | Carbon Tool Steel | Alloy Tool Steel | High Speed Tool Steel | Stainless Steel | Heat-resisting Steel.Poisson's Ratios Metals - Some metals and their Poisson's Ratios.Poisson's Ratio - When a material is stretched in one direction it tends to get thinner in the other two directions.Mineral Hardness - Mohs Scale - The Mohs qualitative ordinal scale characterizes the scratch resistance of various minerals.Metals and Alloys - Melting Temperatures - The melting temperatures for some common metals and alloys.Metals and Alloys - Densities - Densities of some common metals, metallic elements and alloys - aluminum, bronze, copper, iron and more.Metals - Specific Heats - Specific heat of commonly used metals like aluminum, iron, mercury and many more - imperial and SI units.Metals - Corrosion Resistance to Aggresive Fluids - Common metals and their corrosion resistance to aggressive fluids like acids, bases and more.Composition of Steels - Typical composition of AISI steels.

Brinell Hardness Number - BHN - The Brinell hardness test of metals and alloys.

Material Properties - Material properties of gases, fluids and solids - densities, specific heats, viscosities and more.

1112 are indicated in the table below: Carbon Steels Machinability of some common materials related to AISI No. 1112 carbon steel a machinability rating of 100%. The American Iron and Steel Institute (AISI) has determined AISI No. Machinability can be expressed as a percentage or a normalized value.

Machinability depends on the physical properties and the cutting conditions of the material. Machinability of a material can be defined as the ease with which it can be machined.
