Learn How Stainless Steel 304 Makes Medical Devices Possible

Stainless Steel is one of the more versatile materials on the market which allows its use across a wide variety of industries. One of the more popular industries is the creation of common medical devices. This material has been used in the medical industry, since the early 20th century. There are different grades of stainless steel, which are named as per their composition such as 302, 430, 304 and 304L, 316 and 316L, 410, and 430. Due to sanitation policies, the most common four types of SS used in medical equipment manufacturing are 316, 316L, 304, and 304L. However, the 304 SS is favored by most medical equipment manufacturers in the world. Why? Stay tuned to this post to know more.

Chemical Composition of the Surgical Stainless Steel 304 SS

The 304 SS is made by alloying metals such as chromium, molybdenum, and nickel. Each of these metal contributes to its chemical and mechanical properties.
• Chromium: This metal helps improve the scratch resistance, and corrosion resistance of the SS.
• Molybdenum: The metal provides desired hardness after machining, and also makes it ideal for creating tools with sharp edges such as scalpels.
• Nickel: The metal provides an extremely polishable and smooth surface, and thus makes the SS variant ideal for medical tools requiring fine detailing and precision machining.

Why is 304 Stainless Steel Ideal for Medical Applications?

Stainless Steel (SS) type 304, also known as A2 is widely used for medical applications due to its following chemical and mechanical properties:
• Antibacterial: The steel helps inhibit the growth of unwanted bacteria and microorganisms.
• Anti-Corrosive: The steel doesn’t react with bodily tissues or fluids. Also, it offers high resistance to acidic or alkaline fluids, which helps avoid disintegration.
• Stain Resistant: The steel is stain resistant, which makes it easy to clean and sterilize. As you know, sterilization is an important requirement in the medical industry.
• Easy Fabrication: The steel variant is easy to fabricate, which makes it a popular choice for medical devices or tools with unconventional designs.
• Durable: The SS 304 alloy gains its durability, and reliability from chromium, molybdenum, and nickel, in addition to iron. This durable construction helps it endure rigorous applications.
• Versatility: The steel has low yield strength, as well as high elongation, which makes it ideal to build various types of medical devices including the following:
o Operation tables
o Kidney dishes, trays, bowls, knives
o Surgical forceps
o Artificial heart valves
o Precise tubes
o Vessels for holding hazardous wastes
o Surgical forceps
o Curettes
o Medical devices with tapped holes and screw threads
o Catheters
o Ear scope nozzles
o Retractors
• Recyclable: The stainless steel is recyclable, which helps medical equipment and tool makers to reduce their carbon footprint.
• Non-magnetic: The medical steel is non-magnetic, which makes them ideal to use in operation theatres, especially when working with magnetic implants.

As the SS 304 comes packed with various beneficial properties, it is no wonder, it is being adopted by medical equipment manufacturers.
