Kachueam carbon steel by friction 1040 grade 10 mm diameter 100 mm connection with friction by the use of time in the rotation so that the heat (Tf) is equal to 3 and 4 5 6 7 8 9 10. Seconds, and press until it caused friction (Pf) 20 25 30 35 equal 15 40 45 50 MPa and mechanical property studies of impact test, hardness test. Tensile test and study of properties through metallurgy research found that the appropriate time to rotate it so that the heat (Tf) is equal to 5 seconds without pulling strength values equal to the appropriate pressure MPa 668.33 finally caused friction when rotated. (Pf) is equal to the value of 30 MPa tensile strength equal to 658.33 MPa and rotational time to heat (Tf) is equal to 3 and 4 5 6 7 8 9 10. Second, the ability of the average impact resistance test 428.625 J/cm2 is equal to the pressure finally caused friction when rotated (Pf) Given a value for probability, impact resistance of samples on average equal to J/cm2 38.875.
