20MnCr5 steel is a low alloyed engineering case hardening steel for parts which require core tensile strength of 1000 – 1300 N/mm² and good wearing resistance.

It is used in boxes, piston bolts, spindles, camshafts, gears, shafts and other mechanical controlling parts.

We are manufacturers of 20MnCr5 steels in India and regularly make sizes from 23.5mm to 80mm in round form. We also manufacture 20MnCr5 in cold drawn bright bar form from 22mm to 63.5mm. Also, we make 20MnCrS5 steel in round-cornered square (RCS) form of sizes 55mm, 63mm and 75mm. You can ask for a quotation to compare with your existing supplier prices.

We can also provide you with 16MnCr5 alloy steels and 16MnCr5/20MnCr5 dual certified steels.

One of the unique properties of 20MnCr5 steel is its ability to be case-hardened. This process involves heating the steel to a high temperature, then rapidly cooling it. This causes the surface of the steel to harden, while the interior remains relatively soft.

The case-hardening process also allows for greater control over the hardness of the steel, as different amounts of elements can be added to achieve different levels of hardness. This means that 20MnCr5 steel can be used in a wide range of applications, from gears and shafts to other mechanical components that need to be strong and durable.

This steel is carburising steel used for components requiring high wear resistance surface, coupled with tough cores to resist shock loads and strength to give large service life.

Overall, 20MnCr5 steel is a versatile and durable steel that is commonly used in the production of gears, shafts, and other mechanical components. This steel can be cut, drilled, and machined with relative ease, making it a popular choice for many different applications. Its ability to be case-hardened and its ease of machining make it a popular choice for many different applications. Additionally, its ability to be welded makes it a popular choice for many different types of structures and machines.

The Indian equivalent of this standard can be found in IS9175 (Part 20).
