4130 CF Bar

Alro stocks 4130 Cold Finished Bar - a highly alloyed steel with high nickel and chromium content which assures deep hardening when oil quenched, with high strength characteristics throughout the section. 4130 Alloy Cold Rolled Round Bar/Rods offer good weldability without compromising steel abrasion and impact resistance. Applications include gears, fasteners, and aircraft exterior. 4130 Steel has good machinability, good weldability, and can be heat treated.

Properties

4140 is typically bought to meet chemistry requirements rather than physical requirements. For that reason, physical properties are generally not provided unless requested prior to production. Any material can be sent to a third party after production to be tested for physical properties.

Typical Uses

Applications include gears, fasteners, and aircraft exterior. 4130 Steel has good machinability, good weldability, and can be heat treated.
