Cold Rolled Steel Railing 316 Stainless Steel Pipe ASTM AISI 4*40MM
About 316 Stainless Steel
The 316 grade is also mostly comprised of iron, and similarly contains high amounts of nickel and chromium – at 10-14 percent and 16-18 percent respectively – as well as smaller amounts of carbon, manganese, molybdenum and silicon. For this reason, the 316 grade of stainless steel tends to be the preferred choice for use in marine environments.
Common applications for 316 stainless steel include:
Cisterns and piping used in chemical applications
Commercial kitchens and appliances
Containers used to hold pressurized gasses or liquids
Equipment for chemical storage and processing
Equipment used for industrial and chemical transportation
Marine components
Marine settings
Medical devices and equipment not requiring surgical steel
Outdoor electrical enclosures
Outdoor furnishing
Pharmaceutical manufacturing
Refinery infrastructure
Seafood production and other food processing in saline environments
Stainless steel floats
The main difference between 304 vs. 316 stainless steel involves the 316 grade’s much higher levels of molybdenum, which are typically 2-3 percent by weight and provide better corrosion resistance.
