T1 Herramienta Stee / High Speed ​​/ 1.3355 / HS18-0-1 / SKH2

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:

• Those bearing the symbol T where tungsten is the major alloying element;
• Those bearing the symbol M indicating that molybdenum are the principal alloying element;
• A group of more highly alloyed steels that is capable of attaining unusually high hardness values.

Here we have tool steel type T-1 with the chemical composition, physical, mechanical and thermal properties and other equivalents of T1 tool steels. Except T1 hss tool steel, we are also able to supply T2, T10, T-15 high speed steel etc.

5.Forging of AISI HSS T1 Tool Steel

1. Preheat T1 high speed steel uniformly and slowly to 850-880°C.
2. Increase the forging temperature for T-1 tool steel until 1050-1130°C.
3. El acero para herramientas T1 hss debe enfriarse muy lentamente después de la forja.

6.AISI / ASTM T1 Herramienta Acero Tratamiento térmico y propiedades

Tratamiento	Rango de temperatura	Cooling/Quenching	Notas
Forjando	1700-2100° F	Lento.	Cool slowly in dry sand or in other insulating media.
recocido	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.
Alivio del estrés	1100-1300° F	Cool slowly	Stress relieve after rough machining
Precalentamiento	1500-1550° F		Preheat time in furnace is ¾ Hr. per inch of thickness. Heating up to temperature as slow as possible.
Endurecimiento	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)
Temperamento	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
