Free machining steel costs 15 to 20% more than standard steel, but this higher cost is offset by increased machining speeds, larger cuts, and longer tool life. [ 1 ] The disadvantages of free machining steel are: ductility is decreased; impact resistance is reduced; copper -based brazed joints suffer from embrittlement with bismuth free ...
Machinability is the ease with which a metal can be cut permitting the removal of the material with a satisfactory finish at low cost. [1] Materials with good machinability (free machining materials) require little power to cut, can be cut quickly, easily obtain a good finish, and do not cause significant wear on the tooling.

Tool steel is any of various carbon steels and alloy steels that are particularly well-suited to be made into tools and tooling, including cutting tools, dies, hand tools, knives, and others. Their suitability comes from their distinctive hardness , resistance to abrasion and deformation, and their ability to hold a cutting edge at elevated ...
Stainless steel is a popular class of material for knife blades because it resists corrosion and is easy to maintain. However, it is not impervious to corrosion or rust. For a steel to be considered stainless it must have a Chromium content of at least 10.5%. [24] 154CM / ATS-34 steels. These two steels are practically identical in composition ...
