high-speed steel with high contents of the nitrogen

A powder metallurgy manufactured high-speed steel with high contents of the nitrogen in form of a body, which was formed by compression of the alloyed metal energy, has the chemical structure in the weight %; 1-25 C, 1-3,5 N, 0.05-1.7 manganese, 0.05-1.2 silicone, 3-6 CR, 2-5 MO, 0.05-5W, 6.2-1.7 (V+2 note:), Balance iron and unavoidable impurities in the normal quantities, where the quantity of, on the one hand, the carbon equivalent, Ceq, expressed as formula (i) and on the one hand the vanadium equivalent, Veq, expressed as Veq=V+2 note: , so balanced relative ton are that the quantities of the mentioned elements, expressly in the designation of the mentioned equivalent, lie within the range A1-B1-C1-D1-A1 in the system of coordinated in the illustration, in which those Ceq/Veq CO ordinates of the points A1-D1 A1 are: 4.5/17; B1: 5.5/17; C1: 2.5/6.2; D1; 1.5/6.2. The structure of the steel in hardens and moderated condition, contains of 12-40 volume. - % hard affair of the existing particles of the kind of MX, which are distributed evenly into the matrix of the steel, in which M in mentioned hard affair of the kind of MX essentially of vanadium and/or niobium consists, and X of weight % carbon and 50-70 nitrogen consists weight % 30-50.

Advantages of Cutting Tools made using High Speed Steel

select high-speed steel cutting tools for shorter runs of production in the applications where working conditions limits the use of hard and brittle substrates. These tools issue lower abrasion resistance and primarily less heat resistance than cutting tools made of carbide. high-speed steel has the maximum work hardness of 65 HRC. These kinds of the saws, which does not become drilling equipment and other cutters are not recommended for applications which include hard or abrasive materials or high cutting speeds.

High speed steel cutting tool can be used to munufacture drills bits and drill, milling cutters, and end mills, dovetails, angle and double angle cutters, slitting saws and t-slots, keyseats, chamfer cutters, milling cutters.

Effects on Powder Metallurgy Steel Forgings properties

The effects on the mechanical properties of the parts of steel subjected to a heat treatment of the powder metallurgy (P/M) were given. Three powders, AISI 4650 and modified powders of AISI 4600 mixed with graphite to pay to 4640 the composition, and powders it AISI 4650, were made compact in preforms and heat forged in a hot and closed matrix. The studied variables were the density of preform, method of lubrication, preforms binder (time, temperature and atmosphere), forging the pressure (tsi 20 and 40) and the temperature (1850F, 2000F and 2200F), and forging the report/ratio (0.85 and 0.95). Relationship between porosity connected together and the porosity of total for the various densities of preform was given. A density higher makes the temperatures required compact of agglomeration due to the restricted mobility of reducing gases in the pores. The lubrication of wall of matrix was comparable with mixed lubrication, and it simplified operations of agglomeration of mixture and powder preform.
