Alloy Steel Grades

Alloy Steel grades are carefully selected and evaluated to fit exact applications specified for their exhibited mechanical properties.

Alloy steel has various grades that are applied mostly in aerospace industries and components for the excellent properties they possess. Alloy steel grades are critically examined and evaluated for their designated applications. The different mechanical properties found in alloy steel grades may differ to quantity and quality according to number.
Many manufacturers and industrial engineers use alloy steel out from a vast number of alloy steel grades, especially in aircraft construction. Alloy steel is known for its lightweight properties and high corrosion and abrasion resistance that make it withstand even at elevated temperatures.
