"high carbon" steel, and it is used in the shop as tool steel. One-tenth. per cent of carbon gives steel a tensile strength of 50,000 to 65,000. pounds per square inch; two-tenths per cent gives from 60,000 to 80,000; four-tenths per cent gives 70,000 to 100,000, and six-tenths per cent. gives 90,000 to 120,000.

Final hardness is at the die caster’s discretion and should be selected based upon steel grade, size, and die design. Do not temper below 1000° F (540° C). Lower hardness is specified for larger tools to give better toughness. High hardness (up to 52 HRC): Increased wear resistance and …

2.1 Analysis Of The Variety Of Approaches To Machining Due To Steel Hardness/Tolerances. Tool steel is used for the punch and die components. In its annealed state it can be milled or turned, ensuring to leave a grinding allowance. Heat treatment is then used to harden the tool steel. This tool steel alloy contains other elements such as carbon ...
What is Hardness of Tool Steel - Definition | Material Properties
3.5 Double/triple-tempering of tool steel is described in terms of its purpose. 3.6 Tempering methods and temperature are described in terms of effect on tool steel hardness, toughness, and dimensional change. 3.7 Materials suppliers’ data is referred to for information on depth of hardening for tool steel components at given diameters.

Hardenability is a measure of the steel’s ability to reach hardness, both absolute hardness (at surface) and in depth of hardening (hardness at center). Toughness is a measure of the steel’s ability to withstand stress (resistance to shock, flexibility, deformation, etc) Each different alloying metal will change the properties of the steel.

Hardness of tempered tool steel was enhanced by 20.31% and 167.48% after nitriding and TiCrN coating. There may be possible reasons for enhancement of hardness, one of them is that the coating crystalline comprises lower grain size (0.0144 µm) than the tempered (2.61 µm) and nitrided (1.89 µm) crystalline whereas, another may be due to ...
