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.
Does the SS304 round bars steel sword brand brand need to be welded? Welding stainless steel brand is very different than welding carbon steel, C blade , and can lead to problems trouble such as intergranular corrosion, erosion , hot cracking and stress fracture and tension corrosion cracking. Martensitic stainless steels sword like 410 tend to be brittle and are not readily formable. Austenitic stainless steels brand generally provide the most corrosion resistance underground because of their high amounts senior high school amount of money of chromium. Austenitic stainless steels also have more nickel than other stainless steels, so a grade mark like 316 will have greater toughness huskiness and ductility than ferritic and martensitic stainless steels. Duplex stainless steels can be used to avoid the stress corrosion cracking associated with austenitic stainless steels. Does the stainless steel need to be heat high temperature treated? If the stainless steel is going to be subjected
