95MnWCr5 1.2825 Alloy Cold Work Tool Steel
Type:Round bar
Delivery condition: Annealed black surface/Turned bright surface/Q+T
Products Description
95MnWCr5 steel is a kind of cold-worked die steel. The standard stipulates that the cold-worked alloy 95MnWCr5 steel is an alloy die steel with high hardenability. Due to the carbide formed by tungsten in steel, this steel has more excessive carbide and higher hardness and wear resistance after quenching and low temperature tempering. In addition, tungsten also helps to maintain fine grains and make steel obtain better toughness. Therefore, the tool made of cold-worked alloy 95MnWCr5 steel has less edge collapse and can better maintain the shape and size of the blade.

Processability
The long viscous chips indicate the machinability of the alloy. It can be processed in the annealing state, but the H1150M state will produce the best effect. If the parts are processed in this case, the parts need to be processed after solution treatment before final hardening.
1.2825 Heat treatment
Condition A-Soak at 1900 F (1038 C) for 30 minutes and then cool to below 60 F (16 C) to achieve complete martensitic transformation. Condition H 950 - Condition A material treated at 900 F (482 C) for 1 hour, air cooled. Condition H925, H1025, H1075, H1100, H1150 - Soak the solution treated material at the specified temperature for 4 hours, air cooling, condition H1150M - Soak the solution treated material at 1400 F (760 C) for 2 hours, air cooling, and then heating to 1150 F (620 C) for 4 hours and air cooling.
Welding
This alloy should not be connected by oxyacetylene welding. AWS E/ER630 filler metal is recommended if required.
Forging
Soak at 2150 F (1177 C) for 1 hour before forging. Do not work below 1850 F (1010 C). Post-work solution treatment is required before final hardening.
