CARPENTER BARTO is a cold-melt, grain-controlled, electric-furnace chromium-nickel tool steel. It was developed for applications requiring extreme toughness. Barto's extreme toughness is developed at the expense of some wear resistance; however, it will harden to Rockwell C 55/56. Typical applications are clutch parts and expander punches. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties as well as fracture toughness. It also includes information on forming, heat treating, machining, and surface treatment. Filing Code: TS-444. Producer or source: Carpenter.

CYCLOPS L6 is an oil-hardening tool steel recommended for any tool-steel application requiring relatively great toughness, or where intricate shapes preclude the use of water-hardening steels. It is also recommended for machine parts and other components that require an excellent combination of hardness, wear resistance, compressive strength and toughness. Typical applications include dies of various types, arbors, punches, pinions, shear blades and clutch parts. 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-375. Producer or source: Cyclops Corporation.

CARPENTER No. 408 Punch Steel was developed specifically to meet the needs of the pharmaceutical industry. It has the necessary wear resistance to withstand the severe conditions of handling the abrasive materials that must be pellitized. It also has high strength in combination with excellent toughness and resistance to splitting stresses. It has found a number of other uses requiring resistance to shock loading and splitting stresses, such as clutch parts, vise jaws and expander punches. This datasheet provides information on composition, hardness, and tensile properties as well as fracture toughness. It also includes information on forming, heat treating, machining, and surface treatment. Filing Code: TS-368. Producer or source: Carpenter.

SAE 4147 is a medium-carbon low-alloy steel with relatively high hardenability and good resistance to abrasion, fatigue and impact. It is recommended for moderately severe service. Although nominally an oil-hardening grade, SAE 4147 may be water hardened if suitable precautions are taken to minimize the danger of cracking during quenching. It has a relatively low tendency for the development of temper embrittlement during tempering in the range 850-1100 F. Typical applications comprise gears, shafting, machine-tool parts, clutch parts and connecting rods. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties. It also includes information on corrosion resistance as well as forming, heat treating, machining, joining, and surface treatment. Filing Code: SA-375. Producer or source: Alloy steel mills and foundries.

AISI 4142 is a medium-carbon low-alloy steel recommended for moderately heavy-duty service. It is nominally an oil-hardening grade; however, it may be water hardened if suitable precautions are taken to avoid cracking. It has a relatively low tendency to develop temper embrittlement. It has a variety of applications including bolts, crankshafts, wrenches, clutch parts and shafting. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties. It also includes information on corrosion resistance as well as forming, heat treating, machining, and joining. Filing Code: SA-370. Producer or source: Alloy steel mills and foundries.

ALUMINUM 392.0 is a hypereutectic aluminum-silicon alloy developed for die castings which require high resistance to wear and abrasion. Applications include variable speed pulleys, automotive clutch friction rings, cylinder liners, sheaves, and brake drums. This datasheet provides information on composition, physical properties, hardness, and tensile properties. It also includes information on corrosion resistance as well as casting, heat treating, machining, and joining. Filing Code: Al-199. Producer or source: Aluminum Company of America.

BRUSH Alloy 10 is a low beryllium, cobalt-bearing copper alloy offering an excellent combination of strength, toughness and conductivity due to an age-hardening heat treatment. It is recommended for springs, clutch rings, resistance welding electrodes and tips, etc. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties as well as fatigue. It also includes information on corrosion resistance as well as casting, forming, heat treating, machining, joining, and surface treatment. Filing Code: Cu-187.
