AISI T15 stee / 1.3202 / DIN S12-1-4-5

Désignation par normes

Composition chimique (en% en poids)

Description
High performance high-speed tungsten steel. The high V content gives the steel the best cutting performance and durability. The Co content offers high tempering durability and hot hardness. The steel has proved particularly beneficial in cases where hard materials being processed cause a high degree of wear of the cutting surface, and where the cutting surface is at an elevated temperature.

Applications
High speed steel, for heavy-duty operations. Turning knives, milling cutters for rough machining, smoothing.

Propriétés physiques (valeurs moyennes) à température ambiante
Module d'élasticité [10³ x N / mm²]: 217
Densité [g / cm³]: 8.40
Conductivité thermique [W / mK]: 19.0
Résistivité électrique [Ohm mm²/ m]: 0.65
Capacité thermique spécifique [J / gK]: 0.46

Coefficient de dilatation thermique linéaire 10^-6oC^-1

Recuit doux
Chauffer à 820-860^oC, refroidir lentement dans le four. Cela produira une dureté Brinell maximale de 280.

Stress Soulager
Stress relieving to remove machining stresses should be carried out by heating to 600-650^oC, holding for one hour at heat, followed by air cooling. This operation is performed to reduce distortion during heat treatment.

durcissement
1st pre-heating: 400^oC. 2nd and 3rd pre-heating: 850^oC et 850^oC et 1050^oC. Harden from a temperature of 1190-1240^oC followed by oil or air quenching or warm bath approx. 550^oC/air.

Tempérer
Tempering temperature: 3 x at 540-580^oC. Hardness after tempering is 65-67 HRC.

Forger
Température de formage à chaud: 1100-900^oC.

Usinabilité
No data.

Résistance à la corrosion
Corrosion resistance of this alloy is better than that of plain carbon steels. However it will rust unless given protective treatment.
