Answer

Surgical needles are produced from stainless steel alloys, which have excellent resistance to corrosion. [28] All true stainless steels contain a minimum of 12% chromium, which allows a thin, protective surface layer of chromium oxide to form when the steel is exposed oxygen. Since their development during the early 1960s, high-nickel maraging stainless steels have found extensive use in structural materials in many applications that require a combination of high strength and toughness.
