Laboratory and Testing Equipment
Stainless steel plays a role in pharmaceutical processes almost from their start—including drug development's research and diagnostics phases.Typical items using stainless steel in a pharmaceutical laboratory include autoclaves, incubators, and analytical instruments.
Popular Types of Stainless Steel Used in the Pharmaceutical Industry
Like most industries, a few stainless steel grades make up most of the use in the pharmaceutical industry due to their availability, cost, and flexibility. However, some different types of stainless steel are popular in pharmaceutical environments as well.
Some of the Most Common Grades Used Include
316L Stainless Steel: Commonly used in pharmaceutical equipment and process piping due to its hygienic properties, this low carbon grade of stainless steel also offers exceptional resistance to pitting corrosion and crevice corrosion while remaining affordable and easily accessible.
304 Stainless Steel: As one of the most popular grades of stainless steel worldwide and across nearly all industries, this versatile grade increases corrosion resistance while remaining easy to fabricate with or weld. Typical uses include pharmaceutical equipment, storage tanks, and piping.
316Ti Stainless Steel: Thanks to the inclusion of titanium in this alloy, it offers improved resistance to intergranular corrosion and sensitization in extreme temperatures—such as those encountered when welding. It is commonly used in high-temperature applications, such as pharmaceutical reactors and process equipment.
904L Stainless Steel: This high alloy austenitic stainless steel contains molybdenum, nickel, and copper. Including copper means that the alloy provides excellent corrosion resistance in aggressive or acidic environments, including but not limited to resistance against sulfuric acid, acetic acid, formic acid, and phosphoric acid. This makes it ideal for pharmaceutical equipment and piping systems involving strong acids or chloride-neutral aggressive environments.
2205 Duplex Stainless Steel: This duplex stainless steel contains both austenitic and ferritic phases. The result is an alloy with excellent strength and corrosion resistance equally suited to moulding and high-stress applications. Common applications in pharmaceutical processes include reactors and pressure vessels.
As the list above shows, the various grades of stainless steel available make it possible to tailor alloy choices to meet specific needs.Regardless of the process, environment, or solution required, there’s a good chance a stainless alloy or part already exists to suit your needs.
