16MnCr5 steel (1.7131): EN 10084-2008
16MnCr5 steel are alloyed case hardening engineering steels for parts which require core tensile strength of 800 – 1100 N/mm² and good wearing resistance. It is an engineering material typically used to manufacture piston bolts, camshafts, levers and other vehicle and mechanical engineering components. It is a low-alloy steel that is composed of a combination of elements, including carbon, manganese and chromium. The carbon content in this steel is typically around 0.16%, while the manganese content is around 1.00%. Chromium is present in a concentration of around 1.10%.
One of the unique properties of 16MnCr5 steel is its ability to be heat-treated. This process involves heating the steel to a high temperature and then rapidly cooling it. This causes the steel to become harder and more durable, making it a popular choice for gears and other components that need to be strong and durable. Additionally, the heat treatment 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.
Another unique property of 16MnCr5 steel is its ability to be machined and processed easily. This steel is able to be cut, drilled, and machined with relative ease, making it a popular choice for many different applications. It is also relatively easy to weld, which makes it a popular choice for many different types of structures and machines.
16MnCr5 steel is also known for its excellent wear resistance, making it a suitable option for gears and other components that are exposed to high levels of wear and tear. Additionally, it has a good combination of strength and ductility which makes it a suitable option for applications that require a balance of strength and flexibility.
