Product Description

Properties and characteristics of HPM75 non magnetic steel

HPM75 is a high strength Austenitic shape non-magnetic die steel, which can maintain stable austenite in various states. Therefore, HPM75 non-magnetic steel has ultra-low permeability, high high temperature strength and hardness, excellent toughness and weldability, excellent mechanical properties and excellent wear resistance. HPM75 non-magnetic steel has been aging hardening treatment, without any heat treatment; And the steel structure is uniform, the most suitable for precision etching processing.

 

HPM75 non-magnetic steel round bar heat treatment process (HPM75 quenching/tempering process), HPM75 hardness after heat treatment

1. HPM75 non-magnetic steel ingot: heating temperature 1150-1170℃, heating time ≥8h, start temperature 1100-1120℃, end temperature ≥950℃, air cooling;

2. HPM75 non-magnetic steel billet: heating temperature 1140-1160℃, heating time ≥8h, start temperature 1080-1100℃, end temperature ≥950℃, air cooling;

3. Quenching temperature of non-magnetic steel HPM75

4. Tempering temperature of non-magnetic steel HPM75

5. Quenching process of non-magnetic steel HPM75

 

High temperature annealing process of HPM75 non magnetic steel

HPM75 non-magnetic steel annealing temperature 870-890℃, holding 3-6h, furnace cooling below 500℃ out of air cooling. The hardness of HPM75 after annealing is 28-30HRC, and the microstructure is fine grain austenite + uniformly distributed granular carbide. High temperature annealing can improve the machinability of HPM75 steel.

 

Solution treatment process of HPM75 non magnetic steel

HPM75 non-magnetic steel solution temperature 1150-1180℃, salt bath furnace holding 15-20min, box furnace holding 30min, water cooling, HPM75 solution hardness 20-22HRC, metallographic structure: austenite + undissolved primary carbide.

 

Aging process of HPM75 non magnetic steel

HPM75 non-magnetic steel aging temperature 650-700℃, aging 15-20h, air cooling, HPM75 after aging treatment hardness ≥45HRC.

 

Gas nitrocarburizing process of HPM75 magnetic steel

HPM75 non-magnetic steel co-permeability temperature 560-570℃, co-permeability time 4-6h, surface hardness 950-1100hV, nitriding layer depth 0.03-0.04mm.

 

HPM75 non-magnetic steel material quality assurance/quality safety certification:

Tianzheng die steel provides HPM75 non-magnetic steel original steel material certificate to ensure the quality of die steel.
