6.Characteristic of 4140 Steel Round Bar

Chromium molybdenum high tensile steel with yield strength of 550N/mm2.

Chromium renders steel oil hardenable and increase hardenability.

Weldability suffers with increasing chromium content.

High temperature strength and high pressure hydrogenation properties are

promoted by chromium and molybdenum.

Molybdenum significantly reduces temper brittleness.

6.Application of 4140 Steel Round Bar

Commonly used for manufacturing 35CrMo higher than the required strength, large parts of the

important sectional dimensions, such as axis, gear, connecting rod, transmission gears, the

supercharger gear, engine cylinder, spring, spring clamps, 12-2000mm oil pipe fittings, fishing tools and instead of containing nickel steel high.

For main shaft of steamer,boly for 400 °C. Hummar shank.

same as 35CrMo.with big section.supper force.
