Because surgical needle ductility is such an important factor in the selection of surgical needles, a new curved needle ductility test instrument was devised to measure the ductility of needles from three commercial manufacturers. The superior ductility of needles made by one manufacturer was related to the specific alloy, stainless steel ASTM 45500, used in their production. The ASTM 45500 stainless steel has a significantly greater tensile and yield strength than the other stainless steel alloys, accounting for its superior ductility.
由于手术针的延展性在手术针的选择中是一个非常重要的因素，因此设计了一种新的弯曲针延展性测试仪器，以测量来自三个商业制造商的针的延展性。一家制造商生产的针具有卓越的延展性，这与他们生产中使用的特定合金——ASTM 45500不锈钢有关。ASTM 45500不锈钢的抗拉强度和屈服强度明显高于其他不锈钢合金，这就是其延展性卓越的原因。
