WebApr 13, 2024 · High tensile fasteners are heat treated to achieve their tensile strength. This process achieves strength by reducing internal stresses in the material, reducing brittleness, hardening and toughening. While other types of fasteners may also be heat treated, it is a mandatory aspect of high tensile bolts with a view to achieving enhanced strength. WebThere are three basic methods for the checking of torques applied to bolts after their installation; namely, taking the reading on a torque gauge when: 1. The socket begins to move away from the tightened position in the tightening direction. This method is frequently referred to as the "crack-on" method. 2.
Standard Specification for High Strength Structural Bolts and ...
WebASTM A193 Grade B7 is a standard material specification for chromium-molybdenum alloy steel fasteners for use in high tensile, high temperature and special purpose applications. Grade B7 is a heat-treated chromium-molybdenum alloy steel with minimum tensile requirement of 100 ksi, yield of 75 ksi and maximum hardness of 35 HRC. WebTensile Strength: The maximum load in tension (pulling apart) which a material can withstand before breaking or fracturing. Yield Strength: The maximum load at which a material exhibits a specific permanent deformation Proof Load: An axial tensile load which the product must withstand without evidence of any permanent set. north bend ohio post office
