SAE 316 and SAE 316L stainless steel, also referred to as marine grade stainless, is a chromium, nickel, molybdenum alloy of steel that exhibits relatively good strength and corrosion resistance. 316L is the low carbon version of 316 stainless steel. [2] 316L in particular is biocompatible when produced to ASTM F138 / F139. [3]
The tube is attached to the ovary by a thin tissue called the mesosalpinx. The inner tubal lining is lined with cilia.
