A Brief Comparison between Stainless Steel Bolts 304 and Stainless Steel Bolts 316
It is known to all that stainless steel fasteners are widely used in various major constructional projects. From manufacturing cookware to bridges – stainless steel fasteners have various uses in various spheres of manufacturing or construction. Stainless steel fasteners or nuts and bolts come in various specifications. Different specifications have different purposes to serve. Amongst various types of stainless steel fasteners, here we shall discuss about two kinds of fasteners and they are type 304 and type 316.
Type 304 Stainless Steel Fasteners
Stainless steel bolts 304 can be commonly found in the local hardware shops. This type of fastener is generally used for manufacturing furniture, cookware, etc. This kind of bolt and nut is corrosion resistant, temperature resistant and rust resistant. Type 304 consists of 20% chromium, 0.08% carbon and 10% nickel. These steel fasteners show high end corrosion protection and thus they are used for manufacturing cookware stuffs. They can also withstand with heat and do not change shape as well as size due to the effects of heating. Furthermore, type 304 steel is completely rust protective. Even staying at moist environment and being handled with water cleaning regularly, they do not acquire single bit of rust.
Type 316 Stainless Steel Fasteners
Type 316 steel fasteners are vastly different from the type 304, though type 316 is also used for manufacturing several cookware stuffs, like gas ovens, cooking pans, etc. Type 316 possesses 16 to 18 percent chromium and 11 to 14 percent nickel. Additionally, it also contains 2 percent molybdenum. Molybdenum basically helps the fasteners to become more corrosion resistant. Also, due to the increased percentage of chromium, this type of steel nuts, bolts and other fasteners remain shiny as well as lustrous for a long time. Simple method of cleaning with water and then with dry cloth will keep type 316 shiny as well as bright for long time. Due to its supreme chloride corrosion resistance characteristic and other prime advantages, type 316 is gradually replacing type 304 steel fasteners.
Type 316 is more expensive than type 304. However, in terms of effectiveness, type 316 can prove to be more cost-effective than type 304.
