HSS T1 1.3355 round bar

T1 steel is tungsten type tool steel. Very high resistance to wear and to softening. Good toughness and cutting capability. Deep hardening response.

Quick Detail:

T1 1.3355 ROUND BAR

COMPOSITION

C	Si	Mn	P&S	Cr	V	W
0.65-0.80	0.20-0.40	0.10-0.40	0.03max	3.75-4.5	0.90-1.30	17.25-18.75

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 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 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	1022° F-1058°F	Temper T1 tool steel immediately after quenching. Hold for at least 2 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
