1.2344 Steel 1.2344 steel is a high-quality hot work tool steel and is a high-quality, high-carbon alloyed tool steel. Characteristics Good wear resistance at both low and high temperatures High toughness and ductility Good high temperature strength and resistance to thermal fatigue Good hardenability Low deformation during hardening Applications 1.2344 steel, on the other hand, is primarily used for forming extrusion dies. Typical applications include aluminum, magnesium, zinc, copper and aluminum extrusion dies for casting molds, copper and brass extrusions for bushings, spindles, press pads, follower parts, shims, punching dies, dead dies, and engagement rings. In addition, 1.2344 is used in the production of hot stamping and extrusion die forging, hot heading dies, jig dies, hot embossing, punching, and trimming tools. Other applications include plastic molds, hot shear blades and hot extrusion dies.
2738/2738H/2738HH P20+Ni Plastic Mould Steel 1.2737HH IS High Quality Plastic Mould Steel. It is a steel characterized by excellent hardening penetration, good processability, polishability and suitability for photo, this steel is used in the wide field of plastic molds, especially for large arrays with low carbon content, it has greater sealability in comparison to 1.2738. 2738 Mold Steel 1.2738HH Flat Bars is Hardened and tempered steel for plastics processing moulds, with a homogeneous strength even for large dimensions 1.2738HH is generally labelled as Mould Steels. Nickel, chromium and molybdenium are the alloying elements for hardness and toughness. Cold work tool steel with good machinability, excellent polishability, suitable for texturing. Improved through hardenability compared to Mat.No.1.2738, especially for bigger parts. It is a steel characterized by excellent hardening penetration, good processability, polishability and suitability for photo, this steel is used in the wide field of plastic molds, especially for large arrays with low carbon content, it has greater sealability in comparison to1.2738 It can be nitrided to further improve the wear resistance.
Bao steel SW718H-P Classicplastic mold steel SW718H/SW718HH are Prehardened Plastic Mould Steel which are made by Baosteel. Both of them are developed with reference to steel standard AlSI P20+Ni from the US and W.Nr 1.2738 from Germany with modification. SW718HH is delivered with a higher hardness which could provide better wear resistance when comparing to SW718H. Apart from the standard testing procedure by Baosteel,the quality of SW718H
