EN 10083-1 37CrS4 Introduce
In accordance with the EN 10083-1 37CrS4 standard, the steel must have a specific product designator affixed to the product by the manufacturer that identifies key properties of the steel. This designator often includes information about the grade, composition, manufacturer, and manufacturing process. The designation must meet the requirements outlined in ISO 6929, which includes a set of criteria (such as the size of letters and typeset used) that must be followed in order for the product designation to be valid and clear.
Smelting temperature:1436°C - 1664°C

EN 10083-1 37CrS4 Material Mechanical Properties
Fatigue is a measure of the material's ability to withstand cyclic loading without failure. EN 10083-1 37CrS4 steel has an excellent fatigue strength of 125-175 MPa at 1000 cycles which makes it suitable for use in components that are exposed to high frequency and vibration such as gears or shafts. The high fatigue strength can also provide longer life expectancy for these components.
