End Quench testing Jominy testing This apparatus is useful for determining the hardenability of steels by End Quench Test. The test consists of heating a standard size test specimen to a given temperature for a specific period of time, followed by a water quenching at one end under specified conditions and measuring the hardness at various points from quenched end along the length of test piece. Quenching fixtures designed as per ASTM : A 255 – 02 ; IS 3848 – 1966 Principle After heating, the test specimen is kept on the specimen holder where it is automatically centered with respect to water jet. The quick action valve starts impinging the water jet on the specimen end instantly. The well defined water jet is achieved by suitably choosing one of the nozzles provided and its corresponding water head. The suitable arrangement of pump, tank, pipe etc enables to obtain desired correct waterhead for the particular nozzle. Standard test piece dimensions : Dia 25± 0.5 x Length 100 ± 0.5mm FINE MARKETING Manufacturers of Testing Machines (An ISO 9001 company) 15A, NEW BHARAT INDUSTRIAL ESTATE, LAKE ROAD, BHANDUP(W), MUMBAI-400078, INDIA.TEL: 022-2596 5795/2596 5796 EMAIL: [email protected] WEB: www.finemarketingindia.com / www.materialtestingmachines.net www.materialtestingmachine.com / www.metaltestingmachine.com
