Pre Hardened Tool Steel 1.2083H 420H S136H Plastic Alloy Tool Mould Steel Plate
S136 Stainless Tool Steel is a martensitic stainless steel with 12% Chromium which is sufficient to give good corrosive resistance properties. It’s best corrosive resistance is when hardened and surface is ground or polished.It has good ductility in the annealed condition but can be hardened up to 500HB (highest of the chromium grades). Martensitic Grades are known for high hardness and allowances must be made for poor weldability and usually allowances for a final harden and temper treatment. Steel is magnetic and welding is not recommended.

Soft annealing:
750 to 800°C for about 2 to 5 hours
slow controlled cooling of 10 to 20°C per hour to about 650°C; further cooling in air, max. 200 HB
Hardening:
1000°C to 1050°C
15 to 30 minutes keeping curing temperature
quenching in oil/compressed gas/hot bath
obtainable hardness: 53 - 56 HRC
Tempering:
slow heating to tempering temperature immediately after hardening;
minimum time in furnace: 2 hours per 20 mm part thickness;
Tempering twice is recommended.
Application:
Moulds for corrosive plastic materials such as PVC, recycled polymers etc., moulds for chemically aggressive plastics and plastics containing abrasive fillers, mould inserts, dies and gauges for PVC extrusions, screws and barrels for extruders, moulds for automotive, food, medical and optical industry such as spectacles, compact discs, lenses.
