Product Description

Detailed Photos

Standard: ASTM A519
material : 4130/4140
Advantage: Alloy steel round 4140 tubing metric is normally used for heavy-duty industrial applications. Also referred to as Chromoly steel, 4140 round tube is known for strength, resistance to fracturing, abrasion, and impact in high-stress applications.
Description: 4140/42 and 4130 Mechanical Tubing are medium carbon alloy grades, which are widely used for many general-purpose applications that require high tensile strength and toughness. The addition of chromium and molybdenum as alloying elements, combined with heat treatment, provides the combined advantage of hardness, ductility, and strength.
Delivery Condition:Cold drawn/hard (+C) (BK)
Cold drawn/soft (+LC) (BKW)
Cold drawn and stress relieved (+SR) (BKS)
Annealed (+A) (GBK)
Normalized (+N) (NBK)
Quenched and Tempered (QT)

Application

Commercial aircraft, aircraft engine mounts
Military aircraft
Automotive
Machine tools
Hydraulic tools
Auto racing
Aerospace
Oil and gas industries - as forged valve bodies and pumps
Agricultural and defense industries etc
