AISI M42 tool steel is a high-speed steel suitable for cutting tools such as, twist drills, broaches, taps, milling, cutters, saws, reamers etc. In terms of performance, HSS grade M42 is a steel to be used in conditions where the demand for hot hardness is of great importance i.e. where high performance is essential.

Pipa:Pressurized gas, warm oil, or salt. For pressurized gas, a rapid quench rate to ni isalẹ 1000 ° F (538 ° C) 

is critical to obtain the desired properties. For oil, quench until black, 

about 900°F (482°C), then cool in still air to 150 -125°F (66-51°C). For salt maintained at 1000-1100°F (538-593°C), 

equalize, then cool in still air to 150 -125°F (66-51°C).

Gbigbọn:Temper immediately after quenching. Typical tempering range is 1025-1050°F (552-566°C).

Hold at temperature for 2 hours, then air cool to ambient temperature. Double tempering is required. 

For large cross sections, and especially for blanks from which tools will be cut by wire EDM, 

triple tempering is strongly recommended.
