Alloy Steel

Steels that contain specified amounts of alloying elements -- other than carbon and the commonly accepted amounts of manganese, copper, silicon, sulfur, and phosphorus -- are known as alloy steels. Alloying elements are added to change mechanical or physical properties. A steel is considered to be an alloy when the maximum of the range given for the content of alloying elements exceeds one or more of these limits: 1.65% Mn, 0.60% Si, or 0.60% Cu; or when a definite range or minimum amount of any of the following elements is specified or required within the limits recognized for constructional alloy steels: aluminum, chromium (to 3.99%), cobalt, columbium, molybdenum, nickel, titanium, tungsten, vanadium, zirconium or other element added to obtain an alloying effect. Technically, then, tool and stainless steels are alloy steels. In this chapter, however, the term alloy steel is reserved for those steels

Products & Services
Master Alloys and Alloying Additives
Master alloys and alloying additives are alloy element concentrates, grain refiners, hardeners, deoxidants and other agents added into a melt or metal powder blend to produce a particular alloy, modify a melt or alter processing characteristics.
Specialty Steels and Other Iron Alloys
Specialty steels and other iron alloys have specialized or proprietary compositions or properties that are specifically engineered for certain service conditions.
Ferrous Metals and Iron Alloys
Ferrous metals and alloys are iron-based materials that are used in a wide variety of industrial applications.
Carbon Steels and Alloy Steels
Carbon steels are steels in which the main alloying additive is carbon. Alloy steels are steels alloyed with other metals or materials in addition to carbon to improve properties.
Tool Steels
Tool steels are wear resistant ferrous alloys based on iron and carbon with high levels of alloying elements such as chromium, molybdenum, tungsten and vanadium.
