What are the properties that these round bars have?
SAE 4140 is a chromium molybdenum alloy steel that is widely used in the oil and gas industry. The greater carbon content in SAE 4140 material offers higher strength and heat treatment capabilities.

Apart from strength, it also has a suitable weldability property and machinability. In addition, greater carbon content gives higher rigidity; thus, it is primarily used in sectors where greater rigidity and resistance are required over lower carbon grades.

These round bars have a higher fatigue strength, toughness, abrasion, torsional strength, and impact resistance. It should be well heat treated in various ways to give it a combination of properties.

These round bars offer excellent resistance against rust. Due to this property, it is used in rustic conditions. In addition, because of the many efficient features and characteristics, our high-quality SAE 4041 round bars can be utilized in high-corrosive environments.

These Round bars can sustain pitting and crevice corrosion. All these properties listed above make these round bars suitable for many industrial applications.
