Product Details

AISI O1 / DIN EN 95MnWCr5 1.2510 Cold-Work Tool Steel Bar / Rod

 

INTRODUCTION

 

- AISI O1 tool steel has deep hardening properties with fine grain structure with unusual toughness.

- AISI O1 tool steel offers good durability, gives excellent wear resistance and holds a good cutting edge.

- AISI O1 cold work tool steels also has good response to heat treatment with small dimensional changes.

 

We are a better choice of O1 oil tool steel materials supplier with reliable quality and sales service. AISI Tool steel O1 is available in standard de-carb free rounds, flats and squares, as well as the largest size selection in O1 oil steel ground flat stock and drill rod of all the tool steel grades, or as per customized requirements.

 

 

APPLICATIONS

 

O1 steels are mainly used for short run tooling for cold forming dies, blanking dies, and cutting tools operating at ambient temperature.

 

Typical applications for O1 tool steel are blanking, forming, and trim dies, gages, slitting cutters, punches, bolster dies, knock-out pins, thread roll dies, bending dies, plastic mold dies, shims, cams, machine ways, stamps, machine parts, jigs, cutter templates, swaging dies, etc.

PROCESSING

 

Forging of AISI O1 Tool Steel

Heating for forging of oil tool steel O1 must be done slowly and uniformly. Forging of alloy O1 steels can be performed at 980-1000°C, and reheat as often as necessary. But not forge below 800°C. After forging AISI O1 tool steel, cool slowly in lime, mica, dry ashes or furnace. ASTM O-1 tool steels should always be annealed after forging.

 

AISI O1 Tool Steel Heat Treatment

 

Anneal
Annealing must be performed after hot working and before re-hardening.

Heat at a rate not exceeding 222°C per hour to 802-816°C, and hold at temperature for 1 hour per inch (25.4mm) of maximum thickness; 2 hours minimum. Then cool slowly with the furnace at a rate not exceeding 28°C per hourto 538°C. Continue cooling to ambient temperature in the furnace or in air. The resultant hardness should be a maximum of 212 HBW.

 

Stress Relief of Unhardened Material
Heat slowly to 1250° F. Soak for two hours per inch of thickness at heat. Slow cool (furnace cool if possible) to room temperature.

 

Hardening
- Preheat: Warm slightly before charging into the preheat furnace, which should be operating at about 1100°-1200°F.
- Hardening: Heat to 1475 to 1500° F. Soak at heat for 30 minutes per inch of thickness.
- Quench: Quench O1 steel in warm oil and allow to cool in the oil until a temperature of 125°-150°F has been reached, or to where the part can be held in the bare hand, and temper immediately.
- Temper: Normally oil hardening steels need to be single tempered only. However, double tempering may sometimes be preferred. Soak at heat for 2 hours per inch of thickness for each temper. Air cool to room temperature between tempers. The normal tempering range for this grade is 300 to 450° F.

 

Stress Relief Temper
A stress relief temper for hardened material is strongly recommended after significant grinding, or welding, or EDM. Select a temperature that is 25 or 50° F lower than the last tempering temperature used.
