S6-5-2, HS6-5-2, 1.3343 - specification and application

High-speed steel with very good efficiency, ductility, resistance to abrasion and torsion, and impact strength used to work with products with a strength of more than 830 MPa. It is used in the production of drills, blades, knives, spiral drills, thread cutting tools, broaching tools, gear tools, milling cutters, mandrel reamers, end milling cutters, and circular saw segments. SW7M / 1.3343 is prone to decarburization and overheating during heat treatment. After hardening and tempering, it achieves hardness above 63 HRC.

Mechanical properties of SW7M, S6-5-2, HS6-5-2C, 1.3343

  • Hardness in +A delivery condition: <269 HB
  • Hardness in +A+C delivery condition: <319 HB
  • Hardness in +A+CR delivery condition: <339 HB
  • Hardness after hardening and tempering:
    • at 300 ºC = 61,5 HRC
  • at 350 ºC = 62 HRC
  • at 400 ºC = 62 HRC
  • at 450 ºC = 63 HRC
  • at 500 ºC = 65 HRC
  • at 550 ºC = 65 HRC
  • at 600 ºC = 60 HRC
  • at 650 ºC = 52 HRC

Heat and plastic treatment processes of SW7M, S6-5-2, HS6-5-2C, 1.3343 steel:

  • Softening annealing at a temperature of 800 - 900 ºC
  • Relief annealing at a temperature of 600 - 700ºC
  • Heating no. I in a temp. of about 550ºC
  • Heating no. II in a temp. of about 850ºC
  • Austenitizing at 1190 - 1230 ºC (hardening in salt bath and oil)
  • Tempering usually in the range of 550 - 570 ºC
  • Forging and rolling at temperatures 1100 - 900 ºC
  • Nitriding in the temperature range of 510 - 530 ºC

 

In the above mentioned grades the company provides:

  • Drawn bars, hot-rolled bars, high-speed forged bars 1.3343, HS6-5-2, S6-5-2, HS6-5-2C
