美国超级螺栓公司用一种独特的设计和一种新的高强度钢,研制出被认为是世界上最坚固的螺栓系统。该系统由1个高强度、螺栓型、多功能起重螺栓张紧装置,2个淬硬垫圈和1个铅淬火的应力均衡的螺帽组成。这4个部件,加上8个起重螺栓都是由卡彭特技术的新 AerMet100~#合金制作。这种合金具有高强度、高韧性和抗疲劳强度优点。1个1英寸的,12tpi(每寸螺纹数)的螺栓系统经过重复承受150,000磅载荷后没有出现任何断裂迹象。该力与小螺纹面积上的240,000Psi(每平方英寸磅数)应力相
With a unique design and a new high-strength steel, American Super Bolt has developed what is considered to be the most robust bolt system in the world. The system consists of a high-strength, bolt-type, multi-purpose lifting bolt tensioner, two hardened washers and a lead-quenched, stress-balanced nut. These four components, plus the eight lifting bolts, are all made from Carpenter’s new AerMet100 ~ # alloy. This alloy has the advantages of high strength, high toughness and fatigue strength. A 1-inch, 12-tpi (bolt-per-inch) bolting system showed no signs of breakage after repeated loads of 150,000 pounds. This force is equal to 240,000 Psi (pounds per square inch) stress on the small thread area
