Tool Steel Alloys
A tool is in constant movement, either against another tool or work material, which can cause unwanted wear. Tool steels usually contain carbide formers in different combinations to enhance performance and resist cracking, chipping, or breakage.
While Moon Tool & Die Co. can machine, weld, and assemble any material, we work most often with high-speed, hot-work, and cold-work tool steels. Each grade has unique performance characteristics that are worth scrutinizing.
A2 Tool Steel
An air-hardened tool steel that exhibits good toughness and excellent dimensional stability. This versatile material type is used in the manufacture of a wide array of applications, including chuck jaws, dowel pins, hammers, knives, blanking dies, thread-roller dies, long punches, rolls, master hubs, trimming dies, forming dies, precision tools, gauges, coining dies, extrusion dies, mandrels, shear blades, slitters, and cutting tools.
D2 Tool Steel
An air-hardened tool steel with a high amount of carbon and chromium that produces strong wear-resisting properties. It’s a very deep-hardening steel that’s practically free from size change after proper treatment. This tool steel grade has low machinability and grindability with medium resistance to decarburization. It’s perfect for high-volume production, cold-work applications, and high-wear processes. Common parts manufactured with D2 tool steel include blanking dies, forming dies, coining dies, slitting cutters, heading tools, long punches, forming rolls, edging rolls, master tools, drawing dies, shear blades, and gauges.
O1 Tool Steel
An oil-hardened, non-deforming tool steel. Tools and dies made from O1 will have good wearing qualities since the higher tungsten and chromium content exhibits improved anti-abrasion properties. This tool steel type is typically prized for its combination of strength, hardness, and wear resistance. Typical applications for O1 tool steel include blanking dies, bushings, forming dies, master tools, forming rolls, gauges, trim dies.
S7 Tool Steel
An air or oil-hardening tool steel with high strength, impact-resistance, and anti-shock properties. Additionally, it avoids softening at moderately high temperatures. This combination of properties makes it versatile and a good choice for many hot work applications. Common applications for S7 Tool Steel include bull riveters, chisels, concrete breakers, riveting dies, shear blades, swaging dies, powder metal dies, notching dies, dowels, drills, drill plates, hubs, plastic mold dies, cold-forming dies, blanking dies, bending dies, master hobs, and punches.
DC53 Tool Steel
A general-purpose, cold-work die and mold steel with superior strength and toughness. It exhibits high wear resistance and fatigue strength while resisting chipping and cracking. Typical applications this tool steel grade are forming dies, thread-rolling dies, cold-forging dies, gauges, plastic molds, stepped punches, and press-punching dies.
Tool steels are tough and available in a variety of forms, including round bar, flat bar, square bar, precision-ground stock, and plate. Moon Tool & Die Co. can transform tool steel of just about any shape and size into a high-performing finished product.
