Is Metal Right for Your Next Gasket Project?
With so many metals on the market, choosing the right material for your next gasket project may seem like a daunting process. Metals are being used widely for gaskets, whether on their own or in combination with other plastic or rubber compounds. When you are looking at metal, it is important to understand the benefits of each different type available.
Copper and brass materials have similar benefits when using them for gasket projects. They can take a maximum of approximately 600 degrees in temperature before they begin to break down, which is important to know if you are working in an industry that sees high temperatures. They are both ideal for use in areas where there will be steam. Both copper and brass will withstand most chemicals, except for the most powerful oxidizing agents.
GHL and Grafoil have different temperature thresholds, but they are both very resistant to chemicals, except for those that are made to oxidize metals. One area that they have in common is that they can be manufactured into gaskets using either a laminated format or one that is homogeneous.
Stainless steel is widely used for gaskets. There are several different types available depending on your needs. Type 304 can withstand temperatures up to 1000 degrees and is ideal for general purpose uses. It is soft and will stay so even when exposed to heat and will resist corrosion. Stainless steel type 316 doesn’t offer the same strength as 316, but is much more corrosion resistant when exposed to chemical solutions, though it can experience issues in oxidizing acids. Type 410 stainless steel, or chrome, is known to harden when heat treated. While it is not resistant to corrosion, and can be highly magnetic, it is hard and strong for specific uses.
