OBJECTIVE: To apply different cooling rates to various type of steels and determine the effect of cooling rates and steel composition on final hardness values. APPARATUS: Muffle Furnace A Hardness Indenter. A water tank. A oil tank SAMPLE: AISI 1060 steel bar ( The chemical composition : 0.6 % C ) AISI 1020 steel bar ( The chemical composition : 0.2 % C ) AISI H13 high alloy steel bar ( The chem. comp.: 0,35 % C , 5% Cr, 1% V, 1,5% Mo ) 1-) The chemical composition of AISI H13 Tool steel is 0.35 wt % Carbon, 5.00 wt % Chromium, 1.00 wt %Vanadium and 1.50 wt % Molybdenum. 2-) COOLING TYPE Test 1 Test 2 Test 3 Test 4 Test 5 Vickers AISI1020 Furnace Cooled 64 66 68 70 65 119 AISI1060 Furnace Cooled 83 95 95 93 96 195 AISI1060 Water Quenched 65 60 65 65 63 800 AISI1060 Oil Quenched 27 31 30 33 35 528 AISI1060 Aircooling 25 21 26 21 26 260 H13 Aircooling 37 37 37 37 42 372
