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.
SS 304 round bars manufacturer supplier 304 Stainless Steel Round Bar Mechanical & Physical Properties Stainless Steel 304 Round Bars shows great strength quality and in addition remarkable imperviousness to stretch consumption breaking. These are alloys containing chromium and nickel (sometimes manganese and nitrogen), structured around the Type 302 composition of iron. Grade 304 is stainless with the norm "18/8." Even though there are a wide variety of alternatives available, it is the most robust and commonly used stainless steel available; and it has excellent shaping and welding properties. Grade 304's balanced austenitic structure allows it to be drawn extremely deep, without intermediate annealing. This means the steel of this grade is dominant in the manufacturer.
