Product Details
Wear resistance tool steel & High Speed Steel Flat Bars
(1.3355/SKH2/T1)
Smelting Method
Non-Vacuum Induction Furnace + LF + ESR
Feature
T1 is belong to tungsten high speed steel,T1 is a good carbide former used in high speed steels and hot forming tool steels. It is a steel gray metal that increases temperature and red hardness, prevents gain growth and improves toughness of steels.

Heat Treatment Instruction
| Treatment | Temperature Range | Cooling/Quenching | Notes |
| 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) 2275-2350° F (salt bath) | 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. |
| Tempering | (See Chart) | 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 |
