Applications:

The application is decided by T1 steel chemical composition and properties. 

It is mainly used to make complex blades and impact-resistant metal cutting tools. 

It can also manufacture high-temperature bearings and cold extrusion dies. 

It also is used to make gear tools, milling tools, and tools such as punches, cutters and etc.

RELATIVE PROPERTIES

Treatment       Temperature RangeCooling/QuenchingNotes
Forging1700-2100° FSlowCool slowly in dry sand or in other insulating media
Annealing1600-1650° FCool slowly at a rate of 35° F per hour to 1000° FFor best results, insulating media is desirable. Hold at temperature for 2 hours
Stress Relieving1100-1300° FCool slowlyStress relieve after rough machining
Preheating1500-1550° F
Preheat time in furnace is Hr. per inch of thickness. Heating up to temperature as slow as possible
Hardening2325-2375° F(furnace) 2275-2350°F(salt bath)Quench in air or warm oil. To minimize quenching strains, quench in salt at 1000° FFor maximum wear resistance, harden at 2375° F. For maximum toughness and high hardness, harden at 2275° F
Tempering1022° F-1058°FTemper T1 tool steel immediately after quenching. Hold for at least 2 hoursDouble tempering is recommended. The usual tempering time is 2+2 hours.Recommended temperature is 1000-1075° F for cutting tools. 1100-1200° F for shock tools
