high speed tool steel,
hss tool steel bar
AISI/ASTM T1 tool steel is one of the original tungsten high speed steels, although all tungsten steel grades are used to a limited extent because of the cost and questionable availability of tungsten. Of the T group steels, the general purpose T1 tool steels and the high-vanadium-cobalt T15 are most commonly used.
T1 high speed steel is an air or oil hardening tool steel which has good comprehensive performance. HSS T1 tool steel has a high hardness (HRC62~66), strength, toughness and heat resistance, which is an excellent cutting tool material. T-1 tool steel grade is on the whole used for turning, planning & slotting instruments, tapes, twist drill, threading dies, profile slicing instruments, broaching instruments & reamers.
Generally, high speed steels are divided into three groups:
Generally, high speed steels are used for machining at high speeds. HSS T1 steel materials are widely used for:

Forging of AISI HSS T1 Tool Steel
AISI/ASTM T1 Tool Steel Heat Treatment and Properties
|Forging||1700-2100° F||Slow.||Cool slowly in dry sand or in other insulating media.|
|Annealing||1600-1650° F||Cool slowly at a rate of 35° F per hour to 1000° F.||For best results, insulating media is desirable. Hold at temperature for 2 hours.|
|Stress Relieving||1100-1300° F||Cool slowly||Stress relieve after rough machining|
|Preheating||1500-1550° F||Preheat time in furnace is ¾ Hr. per inch of thickness. Heating up to temperature as slow as possible.|
|Hardening||2325-2375° F (furnace)||Quench in air or warm oil. To minimize quenching strains, quench in salt at 1000° F||For maximum wear resistance, harden at 2375° F. For maximum toughness and high hardness, harden at 2275° F.|
|2275-2350° F (salt bath)|
|Tempering||1022 ° F-1058 ° F||Temper T1 high-speed steel immediately after quenching. Hold for at least two hours||Double 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
