EN 10088-1 1.4122 Material Machining Technology
The machining process for EN 10088-1 1.4122 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.
