What is 42CrMo4 Round Bar?
42CrMo4 Round Bar is a chromium-molybdenum alloy steel bar manufactured in a circular cross-section. The grade is commonly associated with 1.7225 and is used for mechanical components that require a suitable balance of strength, toughness and hardenability.
The round bar form is particularly useful for machining operations such as turning, drilling, milling and threading. This makes the material suitable for manufacturing shafts, pins, gears, axles, studs and other precision-engineered components.
42CrMo4 is frequently compared with grades such as EN19 and AISI 4140 because these alloy steels are used for many similar engineering applications. However, material equivalence should always be confirmed against the applicable standard, chemical composition and required mechanical properties.
