1.2738 HH Steel

Steel name: 1.2738 HH
Diagram No.: 2212
Mat.No. (Wr.Nr.) designation: 1.2738 HH
Chemical composition in weight %: 0.25-0.35% C, 0.30-0.60% Si, 1.40-1.70% Mn, 1.40-1.80% Cr, 0.40-0.60% Mo, 0.20-0.60% Ni
Steel group: Tool steel for plastics
Properties: KeyLos PLUS is a special and innovative pre-hardened alloyed steel, suitable for the manufacture of a large amount of injection moulds. This steel has been designed to enhance in the moulds the following characteristics: high degree of homogeneity of hardness and toughness in the section; good weldability, in case of repair; better machinability, reduction in cutting insert cost, shorter machining time; better surface quality and polishability, due to the high cleanliness and fine microstructure; shorter injection cycle time, due to the high thermal conductivity. KeyLos PLUS is obtained through a special 'super clean' manufacturing process and a special suited heat treatment process.
Applications: Plastic moulding: medium and big sized moulds for the automotive industry; moulds for the food industry; moulds for rubber pressing; pressure moulds (SmC, BmC); bolsters. exTruSion: dies and gauges for pVC extrusion; mechanical parts for extrusion presses.
Reference: Not shown in this demo version.

Heat Treatment
Hardening: Temperature: 900°C. Soaking time: 60 min every 25 mm thickness. Cooling: Polymer or water quench.
Tempering: Temperature: See the graph. Soaking time: 60 min every 25 mm thickness. Cooling: Room temperature.
Diagram note: Tempering curve of a sample which has been austenitised at 900 C.
