4142 Flat Ground Stock

AISI 4142 MULTIPURPOSE ALLOY STEEL

This steel, also known as "Chrome – Moly" maintains exceptional fatigue, abrasion and impact resistant qualities as a result of its main alloying elements of chromium and molybdenum. The 4142 product can be heat treated to increase its toughness and wear resistance. On its annealed state it can be readily formed and machined. It is useful in applications that require a lower hardness and less wear resistance than a fully heat treated tool steel, but it can be flame-hardened where a hardness is desired.

Typical applications include:
-  Crankshafts, Gears,  Axies, Shafts
