    Stainless Steel In A Clean Room Environment



    Stainless steel equipment is often used in cleanroom environments because it can meet strict hygiene requirements. Stainless steel is known to be strong, non-porous and able to withstand the most rigorous cleaning processes. Custom stainless steel is also versatile when it comes to design, which allows steel furniture providers to help their customers comply with regulatory criteria by working with them to deliver custom solutions to meet room specifications and dimensions.

    Stainless steel, most notably, type 304 stainless steel, provide excellent corrosion resistance, and easy cleaning and disinfecting. Type 304 stainless steel also operates well in harsh environments.

    Stainless steels, such as Type 304 stainless steel, not only provides excellent resistance to corrosion but it’s also easy to clean and disinfect without loss of the properties and their durability for operating in a harsh environment. The ability to clean type 304 stainless steel is often compared to that of glass – it has no pores or cracks that might collect dirt, grime, or bacteria, and it can often be cleaned with soap and water, then disinfected.

    It is important to note, that operating with stainless steel in an acid or alkali environment can damage the surfaces of the handling area. Specifically, this type of environment often creates surface pitting that retains bacteria and contaminants. Type 304 stainless steel is basically inert to most acids and alkali. As such, it avoids the risk of corrosion creating contamination traps.

    Furniture and equipment made from type 304 steel can withstand the most rigorous cleaning without corroding, whether by high bar pressure cleaning, thermal high temperature, or chemical detergent cleaning. Further, it maintains structural integrity even at 870°C and chloride content up to 200/mg/l.

    If more extreme conditions exist, type 316 stainless steel should be used as it includes more nickel and molybdenum, which offer more stringent corrosion resistance effective against rigorous cleaning routines, including chloride contents up to 500/mg/l.

    At Stainless Fabricators , we can help you find the right stainless steel equipment/furniture for your situation. Because cleanrooms and sterile environments require working around chemicals, your equipment needs to be able to withstand a chemical spill and intense cleaning. We recommend 304 and 316 for such applications, as both are corrosive resistant, and type 316 is commonly used in the pharmaceutical and medical industry manufacturing environments that use an abundance of salt-solution chemicals and cleaners.
