S705 High Speed Steel Bar


S705 high-speed steel is the Austrian Bailu BOHLER standard steel grade, high-toughness high-speed steel containing 4.8% cobalt Co (mass fraction), high wear resistance, high pressure resistance, sintering resistance, general hardness ≥64HRC when used; easy to perform hot and cold processing , Hardness after quenching and tempering is the same as M35 and M42. Supply status and hardness: Annealed state, ≤280HB











Physical Properties:

The well balanced composition produces both excellent toughness and cutting power and makes this economical molybdenum high speed steel a standard grade for all types of roughing and finishing tools, as well as for all tools demanding a high degree of toughness.

Its wide application will help to simplify stock keeping.


Applications : 


Taps, twist drills, reamers, broaching tools, metal saws, milling tools of all types, woodworking tools and cold work tools.

S705(Bohler-Uddeholm) - Molybdenum high speed tool steel. S705 is often listed as a rough equivalent of AISI M41 tool steel, but AISI M35 steel is a direct match.
