EN 10083-2 C50 Introduce
The European standard EN 10083-2 is an important steel standard that governs the delivery conditions for non-alloy and alloy steels for quenching and tempering with a specified minimum yield strength (ranging from 235 to 700 MPa). The standard applies to a wide variety of products, including cold- and hot-rolled, drawn, forged or peeled-rolled flat and long products. These products are suitable for use wherever a good strength is required.
Smelting temperature:1283°C - 1986°C

EN 10083-2 C50 Material Machining Technology
It is also important to ensure a good lubrication process during machining. A suitable lubricant should be chosen depending on the cutting parameters. In most cases, ISO mineral oil is sufficient for lubricating EN 10083-2 C50 steel components. However, for more demanding operations, it is best to use semi-synthetic or full synthetic lubricants.
