304 Stainless Steel tube

304 / 304L stainless steel pipe is a strong, tough metal with high corrosion protection, high temperature resistance and the ability to be sterlized. It has high workability and can be manufactured to tight tolerances and welded. These alloys are the most commonly used of the stainless steel alloys and are a cost-effective choice for most applications.


Application

304 seamless pipe is used for moving liquids or gases in the food processing, diary, petrochemical, chemical, water treatment industries. Welded 304 pipe is used for handrails, posts and poles in marine
