Black Surface Annealing GB Hardened Tool Steel Plate

DIN 1.2083/420/S136 hardened tool steel plate hardened tool mould steel material

1.2083 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.

HEAT TREATMENT:

Annealing:

Heat slowly to 780°C. Slowly cool in furnace.

Hardening:

Pre heat to 600-700°C until heated through. (Austenitizing temperature 1025°C.) Continue heating to the final hardening temperature of 980-1050°.

Tempering:

Heat uniformly and thoroughly at the selected tempering temperatures and hold at heat for one hour per inch of total thickness. Double tempering is recommended.

Nitriding:
Nitriding of 1.2083 gives it a hard surface which is very resistant to wear and corrosion. Howe ver , the nitrided surface reduces the corrosion resistance. Surface hardness after nitriding at 525°C in ammonia gas will be approximately 1000HV.

Application:
mold plates and inserts for working with chemically aggressive plastics; because of excellent polishing, suitable for optical and medical products

Features:
1. Highly quality of corrosion resistance
2. Pre-hardened delivery save forming mould time
3. Good anti-rusty capacity and easy for welding
4. Excellent polish ability and wear-resisting with high toughness
5. Convenient heat treatment for quenched&tempered steel, without deformed
