Astm 4340 Alloy Steel Excellent Durability Advantages - China

Durability advantages of ASTM 4340 alloy steel

Fatigue resistance: ASTM 4340 alloy steel has excellent fatigue resistance.

In applications that are subject to cyclical alternating loads, such as the crankshaft of an automobile engine, the crankshaft is constantly subjected to cyclical bending and torsion stresses during engine operation.

With its fine and uniform organizational structure and reasonable alloy composition, 4340 steel round bars can effectively resist the initiation and expansion of fatigue cracks, greatly extending the service life of the crankshaft, reducing the frequency of repairs and replacements, and reducing the cost of use.

Wear resistance: Through appropriate heat treatment processes, the surface hardness of ASTM 4340 alloy steel can be significantly improved, thereby enhancing its wear resistance.

In the gear manufacturing of the machinery manufacturing industry, gears made of 4340 steel round bars can effectively resist the wear of the tooth surface during the meshing transmission process, maintaining good transmission accuracy and efficiency.

Even under high load and long-term working conditions, it can maintain a stable working state and show excellent durability.
