The processing with the saw is a mechanical processing of the material, which results in a significantly lower unintended deformation and increased hardness for the existing structure, such as the thermal cutting.
Thus, the machined workpiece has a homogeneous structure even at the edge, which does not change in the continuation of the material.
This circumstance allows immediate finishing of the workpiece with milling or drilling . So it is not necessary to anneal the material or make a similar operation beforehand.
Frequently asked questions about material 1.2343:
The material is very well suited for electrical discharge machining (EDM), nitriding (gas or bath nitriding to improve wear resistance), etching and polishing.
Weldability is rather poor. Due to the risk of cracking in tool steels, the strict guidelines of the welding consumable manufacturers must be followed.
In the annealed delivery condition, the hardness is a maximum of 229 HB. After hardening and tempering, hardness values of approximately 48 to 54 HRC can be achieved, depending on the heat treatment conditions.
ESR stands for Electroslag Remelting. This grade offers even higher purity, greater homogeneity and improved impact toughness, making it suitable for intricate tools.
Typical applications include die-casting moulds for light metals, extrusion dies and punches, forging dies, plastic moulds and hot shear blades.
