Tool & Die Steels
RHINO-DIE™ - Pre-Hardened, High Performance Die Steel
(Redi-Die™ Past Protected Trade Name of North American Steel Co.)
Why Choose Rhino-Die?
Rhino-Die is similar to a 4330 alloy. It is made to Clean Steel Production Technology. Rhino-Die provides excellent dimensional stability and is field proven in the following type dies; zinc, aluminum, plastic and rubber molds, and for forming all types of sheet metal. It will accept many forms of surface conditioning, including flame and induction hardening, carbide coating, PVD and nitriding.
Rhino-Die should be considered as a replacement for; 4130, 4140, 4145, 4340, H-13, and P-20. When starting with an annealed alloy you are required to rough machine, then heat treat, then straighten, and finally finish machine the die. This is costly and prone to rework. Many times the die will need to be completely remade, resulting in expensive time lost.
Rhino-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.
Consider the following...
If you are quoting a job, you will be quoting against competitors who are still using annealed tool steels. The added cost will be reflected in their quote to your customer.
Your lead time will be one quarter of the time they require to complete that manufacturing sequence. Your bid will be lower; your lead time will be faster.

General Fabrication Data
Machining: The hardness is furnished at approximately 42Rc, so standard precautions observed for machining hardened alloys prevail. (The chemistry is very similar to a 4330 alloy). Use equipment of sufficient capacity to avoid chatter and vibration. Machine operators should be familiar with machining hardened alloys and tool steels. Increase pressure decrease speed to avoid glazing. (Glazing is similar to flame or surface hardening of the immediate work area.)
Rhino-Die is a through-hardened alloy, which means you should not encounter the hard and soft spots typically found in commercial grade steels.
Drilling: 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: overcarburized 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.
