Alloy Steel Grades
Steel Trading Co. supplies the following alloy steel grades from Karachi, Pakistan.
4140 Alloy Steel
Chromium, molybdenum, and manganese low alloy steel. High fatigue strength, abrasion and impact resistance, toughness, and torsional strength.
View Details4340 Alloy Steel
Versatile alloy steel used in aerospace, automotive, and oil and gas industries for high strength, toughness, and wear resistance. Excellent hardenability and fatigue strength.
View Details8620 Alloy Steel
Case-hardening low alloy steel, carburized for a hard wear surface with a tough core.
View Details5120 Alloy Steel
Low carbon chromium alloy structural steel per ASTM A29. Good toughness, forgeability, and weldability. Responds well to carburizing for high surface hardness with a tough core.
View Details5140 Alloy Steel
Chromium alloy steel, good hardenability and wear resistance for medium-strength shafts and components.
View Details8640 Alloy Steel
Higher-carbon relative of 8620, through-hardening rather than case-hardening, used where higher core strength is needed without carburizing.
View DetailsEN31 Bearing Steel
Classic bearing-quality steel, through-hardening to high, uniform hardness. Chosen for rolling contact fatigue resistance.
