Profile: Rudolf Sajjan (A Unit Of Sajjan Precision Castings ) is a manufacturer and supplier of a broad range of high speed steels. We are an ISO 9001:2008 certified company. We offer a comprehensive range of high speed steels, hot work tool steels and cold work tool steels. High speed steel M1 is used for the manufacturing of cutting tools such as twist drills, end mills and taps. Corrosion resistance of this alloy is better than that of plain carbon steels. Stress relieving to remove machining stresses should be carried out by heating to 650°C, holding for one hour at heat, followed by air cooling. This operation is performed to reduce distortion during heat treatment. Electroslag remelting (ESR) has extensive application in large ingots production from clean alloy steels and high nickel super alloys that offers solutions to power engineering. Chipper knife tool steel is an air-hardening, 8% chromium tool steel which exhibits wear resistance and toughness. This product is typically used in wood chipper knives, slitter knives, scrap shears, plastic granulation knives, tire shredding knives, shear blades, planer knives, punches, and fine blanking dies.
