1144 Stress Proof Steel

1144 Stress proof steel is the perfect material for long-term machining reliability

High Quality 1144 Stress Proof Steel

1144 is a machining grade carefully treated to ease strains created by cold working.

Due to the extremely hard work, it is manganese-free carbon steel with optimum tensile qualities. 1144 Stress proof steel is widely used in high-speed machining of non-ferrous materials.

It is the perfect material for long-term machining reliability – it has a low level of elastic deformity, and its carbon-manganese-free composition makes it resistant to corrosion. With a tensile strength of 175,000 psi and yield strength of 130,000 psi, you can be assured that this grade will stand the test of time.

Machinability & Welding

A typical application for StressProof is in industrial, machine, and tooling applications. 1144 steel is a high-strength, high-hardness steel that has been specially treated to relieve tensions in the metal caused by the manufacturing process.

1144 steel bar is helpful in the manufacture of structural components. That is to say after it has been machined or heat-treated, the 1144 round bar will be less susceptible to warping.

1144 Stress Proof Steel Applications

The 1144 stressproof steel is a type of steel created to resist mechanical stresses. This means that it is often useful in heavy machinery and other items where a lot of force will be put on the metal. It is also resistant to corrosion and rust, making it ideal for humid or wet environments.

This stressproof steel is a kind of low alloy high strength steel. It has good toughness and weldability and can be helpful in many fields. Here are the following applications:

– Agricultural machinery

– Automotive industry

– Building materials

Why buy the 1144 Stressproof Round Bar?

Stress-proof steel is a sheet metal that has been specially treated to resist the effects of stress corrosion cracking. This treatment is applied by heating the steel to its critical point and dipping it in oil, salt water, or other suitable liquid.

The 1144 stressproof round bar is made from a particular type of steel that has been treated with a process called stress-proofing. This process makes the steel more robust and more corrosion-resistant than other types of steel, making it an excellent choice for use in high-stress environments such as bridges and buildings.

Stress-proof steel is a type of high-strength low-alloy steel. It has high yield strength, good toughness, and excellent welding properties. And, it is more resistant to stress than other types of steel.

Here are the advantages of stress-proof steel types;

  1. 1144 steel bar is high-strength low alloy steel with excellent weldability.
  2. Stress-proof steel types have good formability and toughness properties, ideal for manufacturing complex shapes and parts.
  3. The tensile strength of the 1144 stressproof round bar is as high as 102000 psi, which is more than twice that of ordinary carbon steel, so it can be useful in many applications where high strength, weldability, and toughness are required.
  4. The yield point of 1144 stressproof round bar is as high as 60900 psi, which can withstand heavy loads and impacts without breaking or deforming permanently when subjected to repeated loadings or shocks.
