Specifikacije

1.3343/M2 steel is a higher carbon version of the M1 tool (molybdenum high speed steel). 1.3343 alloy has somewhat better wear resistance than M1. Very high resistance to softening at elevated temperatures. Very high resistance to wear. Good toughness and cutting capability.

Deep hardening response.


Aplikacije:

Twist drills, taps, milling cutters, reamers, broaches, saws, and different kinds of knives.

UPUTSTVO ZA TOPLINSKU OBRADU

KALJIVANJE

KRITIČNA TEMPERATURA:
Ac1: 1530°F (832 ℃)Ac3: 1610°F (877 ℃)
AR1: 1430°F (777 ℃)AR3: 1380°F (749 ℃)



Predgrevanje:To minimize distortion and stresses in large or complex tools use a double preheat.

Heat at a rate not exceeding 400°F per hour (222°C per hour) to 1100°F (593°C) equalize, then heat to 1450-1550°F (788-843°C). 

Za normalne alate, koristite samo drugi temperaturni raspon kao jedan tretman predgrijavanja.       


Kaljenje:Temper immediately after quenching. Typical tempering range is 1025-1050°F (552-566°C). Hold at temperature for 2 hours, then air cool to ambient temperature. Double tempering is required. For large cross sections, and especially for blanks from which tools will be cut by wire EDM, triple tempering is strongly recommended.


PREDNOST:

1.High speed tungsten-molybdenum tool steel;

2.High wear resistance;

3.High decarbonization.
