1144 Stressproof

1144 steel is a type of medium carbon steel that has been resulfurized and possesses excellent free-machining qualities.


The 1144 stress proof steel round bar stock is well-known for its high sulfur content, which contributes to its excellent machinability.

All About 1144 Stressproof

This high-quality steel product offers exceptional protection against rust and corrosion and boasts excellent shear strength, enabling it to withstand extreme loads without cracking or breaking. In fact, 1144 steel is a new high-strength steel that can withstand force without fracturing, making it one of the strongest materials in modern engineering projects.

Compared to other steels like A36, A283, and A572, which were not as strong, 1144 stress-proof steel offers superior strength due to its unique blend of high carbon and low alloy content.

Stress-proof steel has been specially designed to resist high levels of stress and is expected to be used in various industries, including construction and other fields where heavy loads are placed on the metal.

1144 Stress Proof Steel Applications

1144 stress proof steel is a new alloy with exceptionally low yield strength, allowing it to be bent or twisted without breaking. Due to its ability to withstand harsh environmental conditions, its demand has increased in various structural applications.

Thanks to its machinability and wear resistance, one of its most common applications is in manufacturing bushings, driveshafts, king pins, spindles, and gears. However, due to its high sulfur content, it can become brittle during welding.

Stress-proof steel is designed to withstand high temperatures and pressure, making it suitable for various applications, including civil engineering, industrial manufacturing, offshore oil drilling platforms, and nuclear.

The creation of 1144 stress proof steel has made it easier for the construction industry to build resilient buildings and bridges against natural disasters, as it is stronger and can withstand significant bending and twisting.
