Products Specification of AISI5140 Alloy Steel

AISI 5140 steel 1.7035 structural alloy steel

Description

5140 steel has good comprehensive mechanical properties and is one of the most widely used steel types, used for manufacturing parts of medium speed and medium load, such as machine tool gear, shaft, worm, spline shaft and so on. The tensile strength, yield strength and hardenability of 5140 alloy steel are higher than 1045 steel, with higher fatigue strength and good toughness, normalizing or tempering machinability are very good, annealing machinability is also good, generally used after tempering treatment.

Heat Resistance

SAE/AISI 5140 steel has excellent heat resistance when it is exposed to temperatures up to 1100°F (593°C). At higher temperatures, the material’s strength decreases somewhat but still remains strong enough for use in many applications. When exposed to temperatures above 1100°F (593°C), the material may become soft and lose its shape but will not melt until it reaches 2700°F (1482°C).

Heat Treatment

SAE/AISI 5140 steel can be hardened by heating it up to 1000-1100°F (538-593°C) followed by quenching in oil or air cooling. This process increases the hardness and tensile strength of the material while maintaining its toughness. The material can also be tempered at lower temperatures after quenching for further strengthening.

Machining

SAE/AISI 5140 steel can be machined using conventional methods such as turning, drilling, milling, sawing, grinding, etc. The material responds well with high-speed tools such as carbide-tipped cutting tools, which are capable of achieving a better finish than other tool materials such as HSS or cobalt steels.

Applications

Gear, shafts, Alloyed case hardening steel for parts with a required core tensile strength of 1000 – 1300 N/mm² and good wearing resistance as boxes, piston bolts, spindles, camshafts, gears, shafts and other mechanical controlling parts.Especially in wheels and stopcock.

Applications included worm, spline shaft, main shaft, oil pump rotor, sliding block, lantern ring, etc.
