Product Description

Product Description

 

1.2083 Forged Flat Bar  4Cr13 Plastic Mold Steel 420

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.  420/1.2083 steel is magnetic and welding is not recommended.

Heat Treatment of 1.2083 Steel

Annealing: 760 to 800ºC, slow cooling in furnace (10-20ºC/hr), down to approx. 600ºC, cooling in air. Hardness after annealing: max. 230HB.

Stress relieving: approx. 650ºC, slow cooling in furnace. Hold in neutral atmosphere for 1 to 2hours.

Hardening: 1000 to 1030ºC, oil. Quenching: oil.  Hot bath at approx. 300ºC. Hardness obtainable, approx. 56 HRC.

Tempering: Slowly heating to tempering temperature right after hardening. Recommended to temper 2 or 3 times.

Tempering ºC	100	200	300	400	500
HRC	55	53	52	51	50

* Hardening temperature: 1000ºC, specimen size: dia25mm

Properties:

Well hardening with minimum distortion, very good resistance to wear and compression. In the heat treated condition this steel grade allows a very high polish

Applications:

Inserts and smaller moulds for injection and compression of corrosive plastic materials.
