Surgical stainless steel is a grade of stainless steel used in biomedical applications. The most common "surgical steels" are austenitic SAE 316 stainless and martensitic SAE 440, SAE 420, and 17-4 stainless steels. [1]
Surgical steel is a variety of stainless steel that’s used in biomedical applications. Sometimes referred to as surgical stainless, surgical steel has no formal definition. Still, stainless steel varieties with the greatest levels of corrosion resistance are those designated for biomedical use.
Surgical stainless steel is an iron-based alloy containing chromium, nickel, molybdenum, and small quantities of carbon. The 316L (F-56 according to ASTM) is the most commonly used form of stainless steel for orthopedic applications.
29 mar 2022 · Surgical steel is a low-carbon steel containing high concentrations of chromium. This chromium reacts with oxygen in the air to form a stable oxide bond that helps prevent rust. Surgical steel is also nonporous, making it more hygienic for use in clinical environments.
💡 While both surgical and stainless steel are corrosion-resistant alloys, surgical steel stands out with its higher purity, enhanced biocompatibility, and specialized medical applications. Understanding Stainless Steel: Composition and Properties
Surgical steel, on the other hand, is a specific type of stainless steel designed for biomedical applications. It typically includes alloys like chromium, nickel, and molybdenum, ensuring enhanced corrosion resistance and biocompatibility required for medical instruments and implants.
Stainless steel, with its versatile composition and durability, is widely used in various industries, while surgical steel, with its higher nickel content and enhanced corrosion resistance, is specifically tailored for medical and surgical purposes.
