SOLAR TOOL STEEL is a very tough water hardening tool steel. Even at Rockwell C 59/60, it will bend before breaking. If medium and large sections, the steel develops a hard case and tough core when hardened. This datasheet provides information on composition, physical properties, and hardness. It also includes information on forming, heat treating, machining, and joining. Filing Code: TS-32. Producer or source: Carpenter. Originally published as Solar, April 1955, revised September 1991.

CARPENTER SOLAR alloy is an extremely tough, water-hardening tool steel. Large sections harden to a hard case with a tough core.

Filing Code: TS-494. Producer or source: Carpenter.

WATERDIE EXTRA is a high-quality water-hardening tool steel alloyed with chromium to give increased depth of hardened case with added resistance to abrasion. When quenched in water or brine, it develops a deep, uniform high-hardness case with a tough shock-dampening core. This steel gives outstanding performance in large-section tools and dies that demand the strength of an extra-deep hardened case backed by a tough core. This datasheet provides information on composition, physical properties, hardness, and elasticity. It also includes information on forming, heat treating, and machining. Filing Code: TS-477. Producer or source: Columbia Tool Steel Company.

COLUMBIA SPECIAL is the manufacturer's highest quality best grade of water-hardening tool steel. It contains small amounts of chromium and vanadium. Its manufacture is controlled closely to insure uniform predictable hardenability. When brine quenched it develops a uniform high-hardness case of medium depth with a tough shock-dampening core. It is noted for its combination of high resistance to abrasion and high toughness. COLUMBIA SPECIAL'S many applications include dies for many uses, reamers, taps, drills, punches, gages and wood knives. This datasheet provides information on composition, physical properties, hardness, and elasticity. It also includes information on forming, heat treating, and machining. Filing Code: TS-466. Producer or source: Columbia Tool Steel Company.

CARPENTER H-9 DOUBLE HEADER DIE STEEL was developed specifically to solve chipping, splitting, spalling and cracking in cold header die applications.

GREEN LABEL DRILL ROD is a high-quality, tough, fine-grain, straight-carbon, water-hardening tool steel with a medium hardness penetration. It is supplied with a smooth, decarburization-free surface and can be used with very little machining for applications such as shafts. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties. It also includes information on forming, heat treating, and machining. Filing Code: TS-316. Producer or source: Carpenter.

AISI is a water-hardening tool steel that resists wear and abrasion from four to ten times longer than plain carbon tool steels. When hardened, it acquires a hard-slippery surface that is difficult to scratch. Its many uses for tools include dies for a variety of products, reamers and finishing tools. This datasheet provides information on composition, physical properties, hardness, and elasticity. It also includes information on forming, heat treating, machining, and surface treatment. Filing Code: TS-298. Producer or source: Tool steel mills.

BLACK DIAMOND STANDARD is an electric-furnace-melted, water-hardening carbon tool steel with an excellent reputation for use as the standard in general shop tools requiring extreme toughness and resistance to shock and impact. In the lower carbon ranges (0.50-0.70% carbon), it is used primarily for tools such as pins, punches, hammers and sledges. Black Diamond may be expected to give uniform and consistent results, although no definite limits of case depth or grain size are regularly guaranteed. This datasheet provides information on composition, physical properties, hardness, and elasticity. It also includes information on forming, heat treating, machining, joining, and surface treatment. Filing Code: TS-281. Producer or source: Crucible Specialty Metals Division, Colt Industries.

AISI Type W2 is a water-hardening high-carbon tool steel recommended for general applications. Its vanadium content prevents austenite grain growth and improves its toughness and its resistance to fatigue and abrasion. It is shallow hardening and in sizes over 1/2-inch in diameter, it hardens selectively with a hard, abrasion-resistant surface supported by a softer and tougher core. These characteristics make it desirable for many types of impact tools. This datasheet provides information on composition, physical properties, hardness, and tensile properties as well as fracture toughness. It also includes information on forming, heat treating, and joining. Filing Code: TS-267. Producer or source: Tool steel mills.

Red Star Tungsten is a high-carbon low-alloy tool steel having high hardness, good toughness, and keen cutting edge. It is recommended for cutting tools, thread rolling dies, paper knives, etc. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties as well as deformation. It also includes information on forming, heat treating, machining, and joining. Filing Code: TS-173. Producer or source: Vanadium Alloys Steel Company.
