Chapel Steel carries an extensive inventory of Alloy Steel plate. Alloy steel is differentiated from other grades of steel by the combination of alloying elements such as silicon, chromium, molybdenum, boron, vanadium, nickel, vanadium, aluminum, etc. These alloying elements increase the strength, toughness, hardness, and wear resistance of the steel. To achieve some of these improved properties the steel may require heat treatment such as Annealing, Normalizing or Quench and Tempering. Alloy steels are typically categorized as Structural, High Strength and Abrasion Resistant.
Structural Alloy Steel is a low alloy steel plate that contains chromium, molybdenum, and manganese. These grades provide high fatigue strength, increased ductility, wear resistance and high torsional strength. Typical applications for these grades include gear and shaft manufacturing, molds, and custom machinery parts.
Quench & Tempered High Strength Steel is a low alloy steel plate that provides high yield strength as well as improved weldability and machining. Improved mechanical properties are achieved through Quench and Tempering (Q&T). This process involves the high temperature heat treatment of steel followed by rapid cooling with liquid resulting in a stronger product. Typical applications for these grades include construction equipment, crane booms, heavy equipment, truck and trailer frames and/or structural applications where yield strength requirements are greater than 100 KSI.
Quench & Tempered Abrasion Resistant (AR) Steel is a high-carbon alloy steel plate that provides increased hardness and toughness. This Quench and Tempered steel is best suited for high impact and abrasive applications such as mining and construction equipment, dump bodies and aggregate conveyors. Abrasion Resistant steel grades are differentiated by Brinell Hardness Number (BHN) and, unlike many other steels, are not governed by any industry specification.
We offer the following Alloy & Abrasion Resistant Steel Plate Products:
