What’s the stainless free-cutting steel grades?

Stainless free cutting steel or stainless machining steel is a kind of alloy steel in which sulfur, lead, calcium, selenium, tellurium and other free cutting elements are added to improve its cutting ability. These free cutting element compounds lubricate the cutting tool and reducing the cutting resistance of the stainless steel, thereby reducing the surface…

How does Mo effect the high speed steel?

Element Molybdenum(Mo) was first used as a cost-effective alternative element for tungsten in tool steels and high speed steels(HSS). Mo has about half the atomic weight of tungsten, and 1% molybdenum is about the same as 2% tungsten. Mo improves the hardness and wear resistance of tool steels, and promotes the formation of an optimal…
