W1 steel tool developed among many others in the steel industry, demonstrates unique properties that are used in most industrial fields. It is the most widely abundant mineral on earth, which is composed of carbon and manganese only, with traces of silicon, phosphorus, sulfur, and chromium. It provides it with a significant hardness, wear resistance and very good toughness values, which further boosts tooling and machining quality. Tool steel W1, in turn, is very often given classification ASTM A686-92. The grades that are the specifications of alloys can be classified into different types of use by their hardness, machinability and also dimensional stability. The list of its mechanical characteristics like strength, hardness, and impact resistance given in the form of graphs helps users choose the suitable material and plan structural design. The table, chart and PDF documents which provide a complete information about W1 tool steel, such as composition, heat treatment recommendations and applications which engineers, metallurgists and manufacturers find very useful in the process optimization.
W1 tool steel is a carbon steel containing 0.95-1.05% carbon which is generally used for low-to medium-hardness applications. It contains in small proportions the metals, namely, manganese, silicon, and sulfur. Being rich in carbon content, W1 alloy showcase good wear as well as hardness, which positions it as a perfect fit for various tooling tasks. That alloy is ideal for its structure as it has a good toughness and strength; however, it doesn’t have the chromium content needed for resistance to corrosion. This material is most commonly used in the forging and woodworking industries where W1 steel's edge retention and industrial applications are highly valued.
