Heat Resistance

With its outstanding heat resistance, Alloy 1075 steel is the perfect alloy steel for many industrial applications. It has a homogenous microstructure and exhibits impressive hardness when quenched, making it especially suitable for pressurized components operating at high temperatures. The strength and workability of this steel depend on its carbon content; higher content makes it more difficult to work with but increases its wear resistance. This alloy steel is often used in the manufacture of hand tools, axles, forging presses, springs, and saw blades – among other uses that require high levels of heat and pressure resistance over extended periods of time.


Machining 1075 steel is a breeze if you know the right techniques. This type of steel is known for its high carbon content and ability to harden, making it great for making knives, swords and other tools. To get the most out of machining SAE / AISI 1075 steel, take note of its low red hardness; as such, it’s best to keep cutting speeds on the lower end so that heat build-up isn’t an issue. Using sharp tooling with plenty of lubricant or coolant is also recommended for high-precision cuts. Ultimately, the correct approach when machining SAE / AISI 1075 steel ensures maximum efficiency and comes away with a finished product that meets your expectations every time.

Corrosion Resistance

AISI/SAE 1075 is a quality carbon steel that offers excellent corrosion resistance. It has heat-treating capabilities and is reconfigurable, allowing it to be moulded into a variety of shapes and forms. Its versatility makes it ideal for applications that need superior protection from the elements, such as bridges and secondhand cranes. With its high carbon content, AISI/SAE 1075 also has strong wear properties that are resistant to both abrasion and shock loads. Its toughness and malleability give it an edge over other steels in many industrial applications.


AISI / SAE 1075 is a medium to high-carbon steel that has excellent weldability. This grade of steel is often used in the making of springs and knives due to its good wear resistance and ability to attain a sharp edge. If you are looking for steel that has good weldability and machinability, as well as high carbon content, then AISI / SAE 1075 might be the right choice for your next project.
