Abstract AISI 1566 is a high-carbon (nominally 0.66% carbon) steel containing 0.85-0.15% manganese. Its hardenability is low and on austenitizing and liquid quenching it develops a hard (martensitic) surface with a soft, ductile core. It can be used in the hot-rolled, annealed, normalized, cold-worked or liquid-quenched-and-tempered condition for a wide range of applications. It has good machinability and good workability. Its many uses include springs, shafts, hand tools, railway parts and agricultural machinery. 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: CS-100. Producer or source: Carbon steel mills.

Abstract AISI 1551 is a medium-carbon steel containing relatively high manganese (0.85-1.15%) for a carbon steel. It can be used in the hot-rolled, annealed, normalized, cold-worked or liquid-quenched-and-tempered condition for numerous applications. It has a combination of good machinability and good workability. Its many uses include hand tools, machinery parts, springs and agricultural machinery. 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: CS-80. Producer or source: Carbon steel mills.

Abstract SAE 10053 is an oil or water-hardening machinery and tool steel for applications where a shallow-hardening steel of high strength with moderate toughness meets the requirements. It is commonly used for parts where induction hardening or austempering are employed. SAE 1053 is recommended for agricultural machinery and tools, hand tools, shafts, springs and heavy-machinery parts. 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: CS-70. Producer or source: Carbon steel mills.

Abstract SAE 1345 is a through-hardening, manganese alloy steel with intermediate hardenability. It is most commonly used where good strength is needed but low-to-medium toughness is sufficient. Its wide range of uses in tools and machinery includes hand tools, gears, shafts, bolts and housings. 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-425.

Abstract AISI 4161 is a low-alloy steel of the chromium-molybdenum type; it contains nominally 0.61% carbon. It has relatively high hardenability and good resistance to abrasion, impact and fatigue. It is an oil-hardening grade and is recommended for moderately heavy-duty service. This steel has a relatively low tendency to develop temper embrittlement when tempered in the approximate range 850-1100 F. Among its many applications are springs, machine-tool parts, shafting, gears, bolts and heavy-duty hand tools. 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-397.

‘Psychotechnics’, Weimar Germany’s science du jour, typically is framed as a symptom of ‘technological media’ – obscuring the persistent significance of ‘dexterity’, ‘skill’ and ‘manual labour’ at the time. More broadly, there is a tendency to construe ‘the haptic’ as predominantly a casualty of modernity: skilled hands replaced by conveyor belts; skilled hands defended by the rearguard actions of arts-and-crafts movements; skilled hands destroyed by industrialized warfare. Drawing on contemporary investigations into the ‘organ of touch’, this essay aims to complicate this picture by reconstructing the proto-ergonomic project of Friedrich Herig, a German engineer, amateur prehistorian and expert on craft labour who rose to distinction in the 1920s as a designer of ‘ideal’ hand tools. Herig’s eclectic sources of inspiration reveal that matters of ‘touch’, far from obsolete, were intimately bound up with matters of tools – their design, uses and putative origins – and thus, with matters of (manual) labour.
