WebUltimate tensile strengths vary from 50 MPa for an aluminum to as high as 3000 MPa for very high-strength steels. Yield Strength Yield strength of tool steel – A2 steel depends on heat treatment process, but it is about 1400 MPa.
WebCoatings were applied on (150 × 50 × 5) mm steel substrate using a robot with 0.9 m/s traverse speed and a step width of 4 mm. The substrate temperature was monitored during spraying with a Fluke Ti300 (Everett, WA, USA) thermal imager, which allowed the temperature of the sample to be kept at approximately 200 °C.
WebA high speed steel "G" drill is being used prior to reaming a 3/8 hole on a piece of 1095 steel with a brinnel hardness of 300. Calculate the RPM setting to perform the drilling and reaming operations.
