EN 10088-1 X2CrNiMoCrWN25-7-4 Introduce
EN 10088-1 is a standard that sets out the thermal properties of steels. It classifies steels according to their thermal properties, such as thermal conductivity, thermal diffusivity, and upper temperature limits. At temperatures higher than the upper temperature limit specified in this standard, the physical and chemical properties of steels can be affected, leading to a reduction in their strength and durability.

EN 10088-1 X2CrNiMoCrWN25-7-4 Material Machining Technology
The machining process for EN 10088-1 X2CrNiMoCrWN25-7-4 steel follows the same basic steps as other types of steel, but it can be more difficult due to the material's hardness and higher resistance to heat. First, the material must be cut, which may be done either by hand-held tools or by a machine. Hand tools such as hacksaws, files, and chisels can be used to achieve the desired shape or size. If using a machine, the appropriate feed rate and cutting tool must be determined in order to obtain the desired results.
