Tool & Die Steels

REDI-DIE™ – High Impact, High Strength, Mold Steel

Why choose Redi-Die?

When machining annealed (Green) steels you are required to rough machine first, then heat treat, then straighten, and finally finish machine the die. Many times errors occur, requiring costly rework. Often, the die never makes it into service, and that means downtime and added expense.

Redi-Die is a pre-hardened high performance die steel that comes to you ready to machine and put into service. It is simple and quick and it does the job.

Redi-Die is a modern tool and die steel (similar to a 4330 alloy), made to Clean Steel Production Technology. It provides excellent dimensional stability and has been field proven for zinc and aluminum die work, plastic and rubber molds, and for forming all types of sheet metal. It will accept many forms of surface conditioning, including flame and induction localized hardening, carbide coating, PVD and Nitriding.

Redi-Die should be considered to replace 4130, 4140, 4145, 4340, H-13, P-20 and even costlier oil and air hardening tool steels.

Are there real advantages with Redi-Die?

The obvious advantage comes from minimizing time lost and expenses, but you may be overlooking the most important advantage: If you are quoting a job, you will be quoting against others who are still going along the annealed tool steel route. Their bids, of necessity, will reflect not only a much higher price (the steel is more money and the processing is expensive and extensive), they will also have unacceptable lead times. You will win more contracts and be more profitable.

Stock Availability

Please enquire as to availability.

We carry large master plates that may be cut to your requirements. We utilize high definition plasma cutting equipment to give you clean, close tolerance (laser quality) edges on thicknesses up to 1-1/2". Plate surfaces are hot rolled to hot rolled tolerances. Blanchard and finish grinding services are available.

Machining Data

The chemistry is very similar to a 4330 Type alloy. The hardness is furnished at approximately 40Rc.

All of the standard precautions observed for machining hardened alloys prevail; Use equipment of sufficient capacity to avoid chatter and vibration. Increase pressure - decrease speed. Avoid Glazing. (Glazing is similar to flame or surface hardening of the immediate work area). Utilize machine operators familiar with machining hardened alloys and tool steels, to the degree of hardness mentioned above.

The hardness of Redi-Die will be throughout, and uniform. Which means you should not encounter the hard and soft spots that can be typically found in commercial grade die plates.

Drilling Data

Cobalt or carbide drills are excellent resources but not required. Hardened twist drills, or High Speed (M-2 type) drills should be adequate. Flood with generous coolant, (20% soluble oil). Use heavy capacity high quality equipment to minimize chatter and vibration. Increase feed and lower speed to avoid "glazing". Where possible, use a hand feed as opposed to a power feed. Power feeds tend to over-power and create small chips which may lodge, or jam. Hand feed allows greater control and "feel" to maintain a scraping type of motion, (long chip). We suggest use of a pilot hole, then follow- up with a reamer type of action. "Dubb", or dull, the edge on the second drill to create a scraping motion, as opposed to a cutting action. For cobalt alloyed high speed tools (example: over-carburized M42), utilize tools with a tapered shank and long helical short bit. Flood with lubricant - 20% diluted soluble oil. Where multiple holes are required you may want to consider tungsten carbide tipped tooling, or solid carbide tools. (ISO K-10 or K-20). Drill bit preparation. Grind away the metal behind the lip to obtain clearance. (10° is preferred). Most drill failures, that occur when drilling hard plate, are along the land, not at the entry point. Thin the point significantly at the entry point.
