High Speed Steels

BÖHLER MC90 INTERMET is the revolutionary cutting material supporting enhanced requirements for improved productivity and highest quality in the gear cutting industry. Its unique alloying composition and properties build the basis for the next generation of tools competing in spheres, where up to now only cemented carbide was applied. Hardenability up to 68 HRC.

BÖHLER S200 – “The old man” This traditional tungsten high-speed steel shows its class as it always has in a tough working environment. High hot hardness and good wear resistance are characteristic of this class.

BÖHLER S290 MICROCLEAN – “The hard stuff” The unusual alloy point of this bridge material between carbide and high-speed steel gives it a hardness of up to 70 HRC. In addition to its hot hardness and good wear resistance, its compressive strength is one of the most important properties of this powder-metallurgical high-speed steel class.

BÖHLER S390 MICROCLEAN – “The decathlete” This grade is our PM steel with many positive usage properties. For twist drills, taps, mills, broaches, or cold-work applications, BÖHLER S390 MICROCLEAN is always a high performer.

BÖHLER S393 MICROCLEAN – “Standardized” This grade complies with the ASTM A600 AISI T15 material standard with higher carbon content. With MICROCLEAN technology, this material shows excellent reliability in many cutting and cold-work applications.

BÖHLER S401 – “The conventional” This grade is part of the family of molybdenum-alloyed high-speed steels and its winning performance is matched by its good cost effectiveness.

BÖHLER S404 – “The discounter” This very economical class is primarily used for spiral drill bits and has a nearly unbeatable ratio of price to performance.

Twist drills, taps, wood working tools.

Böhler S430 “The eco-responsible choice!” Tungsten-molybdenum-vanadium High Speed steel with Aluminum – with good toughness and machinability. The optimal choice for any application, aligning environmental sustainability and budgetary prudence.

BÖHLER S500 – “The fireproof one” In the family of conventional high-speed steels, this alloy combines excellent cutting properties with very high hot hardness.

BÖHLER S590 MICROCLEAN – “The expert” High-speed steel manufactured in a powder metallurgy process, with good hot hardness, compressive strength, and wear resistance. PM technology gives it good toughness and excellent workability, such as the best machinability.

BÖHLER S600 – “The high-speed steel” Ideal for mills, twist drills, and taps, broaches, cold-work tools. BÖHLER S600 is the most commonly used high-speed steel and is the starting material for our customers who deal with high-speed steel.

BÖHLER S607 – “The wear-resistant one” This grade has very high wear resistance while maintaining high toughness and perfectly acceptable machinability.

BÖHLER S630 – “The economical one” Tungsten-molybdenum high-speed steel with aluminum alloy for great toughness and good machinability. Universally usable for taps and twist drills, reamers, metal saws, mills of all types, and woodworking tools.

BÖHLER S690 MICROCLEAN – “The simple one” The tough high-speed steel for challenging machining and cold forming.

BÖHLER S705 – “The industrial one” The conventional high-speed steel for industrial applications in machining. With a well-balanced alloy position and cobalt content, this type always manages to get the job done. Cobalt-alloyed molybdenum high-speed steel with high hardness, excellent cutting properties, outstanding compressive strength, high hot hardness, and good toughness.

The cost-effectiveness of high speed steels is strongly dependent on their alloy components. Strong fluctuations in the raw materials market and resulting price variations have compelled voestalpine BÖHLER Edelstahl to rethink the basic alloy concepts of the high speed steels in our product portfolio. The result is the patented BÖHLER S730 material, which is an economical alternative to the generally applicable standard sort 1.3243 or M35 (BÖHLER S705). Despite its economic advantage, BÖHLER S730 is fully equivalent to the standard 1.3243 in terms of performance.

BÖHLER S790 MICROCLEAN – “The 1st MICROCLEAN” High-speed steel manufactured in a powder metallurgy process, with good hot hardness, compressive strength, and wear resistance. PM technology gives it good toughness and excellent workability, including the best machinability.
