Surgical Steel vs. Stainless Steel: What's the Difference?
Edited by Aimie Carlson || By Harlon Moss || Updated on October 26, 2023
Surgical steel is a grade of stainless steel used for biomedical applications; stainless steel is an alloy of iron resistant to corrosion.
Key Differences
Surgical steel and stainless steel both have a primary foundation in steel, but their applications and specifications differ significantly. Surgical steel is a specific type of stainless steel that meets stringent criteria for biomedical applications. It's known for its resistance to corrosion, durability, and minimal reaction with the human body, making it ideal for surgical instruments and body jewelry. On the other hand, stainless steel is a broad category of steel that's resistant to corrosion because of the presence of chromium. While surgical steel is a type of stainless steel, not all stainless steels can be classified as surgical.
Stainless steel, widely recognized for its silver sheen, is often used in kitchen appliances, cookware, and various architectural elements due to its corrosion-resistant properties. The term "stainless" stems from its ability to resist stains and rusting, attributed to its protective chromium oxide layer. Meanwhile, surgical steel stands apart, primarily due to its biocompatibility. In medical settings, it's crucial that metals don't react adversely with the body, and surgical steel meets this requirement.
Surgical steel's non-reactive nature makes it a popular choice for body implants, surgical instruments, and body piercings. It ensures that there's minimal risk of allergic reactions or infections when in direct contact with the body. Stainless steel, while corrosion-resistant and robust, doesn't necessarily meet the stringent criteria set for medical-grade applications. It's essential to recognize that while all surgical steel is stainless steel, the converse isn't true.
A notable distinction between surgical steel and stainless steel is the variety in the latter's grades and applications. Stainless steel has multiple grades, each with varying alloy compositions catering to specific requirements, from cutlery to building facades. Surgical steel, by contrast, has a narrower scope, emphasizing properties that align with medical safety standards.
