摘要： A stainless steel alloy that exhibits both high strength and toughness as a result of having particular ranges for chemistry, tempering temperatures and grain size. The alloy is a precipitation-hardened martensitic stainless steel with an ultimate tensile strength of at least 1200 MPa, a Charpy impact toughness of greater than 55 J, and a grain size of ASTM 5 or finer. The alloy consists essentially of, by weight, 14.0 to 16.0 percent chromium, 6.0 to 7.0 percent nickel, 1.25 to 1.75 percent copper, 0.5 to 1.0 percent molybdenum, 0.03 to 0.5 percent carbon, niobium in an amount by weight of ten to twenty times greater than carbon, the balance iron, minor alloying constituents and impurities.

摘要： A drill head system including a drill head having a spindle configured to be operatively coupled to a vibration source to cause the spindle to vibrate in an axial direction, the spindle having a passageway. The system further includes a sleeve receiving said spindle therein with a gap therebetween. The sleeve is configured to be coupled to a fluid source to thereby introduce a fluid into the gap and into the passageway of the spindle.
