What are the grades of stainless steel?
What are the grades of stainless steel?
The two most common stainless steel grades are 304 and 316. The key difference is the addition of molybdenum, an alloy which drastically enhances corrosion resistance, especially for more saline or chloride-exposed environments. 316 stainless steel contains molybdenum. 304 stainless steel does not.
What grade is the best stainless steel?
Grade 304
Most stainless steel ordered around the world is Grade 304. It offers the standard corrosion resistance, formability, strength, and easy maintenance for which stainless is known. While 316 comes in second in terms of quantities sold, it offers vastly superior corrosion resistance to chlorides and acids.
What is the difference between grades of stainless steel?
One notable difference between 304 and 316 stainless steel is their levels of nickel and chromium. The former grade usually has a higher chromium content while the latter generally contains more nickel.
Is 304 or 316 stainless better?
Though the stainless steel 304 alloy has a higher melting point, grade 316 has a better resistance to chemicals and chlorides (like salt) than grade 304 stainless steel. When it comes to applications with chlorinated solutions or exposure to salt, grade 316 stainless steel is considered superior.
How can I tell if my stainless steel is 304 or 316?
Try the magnet test. If the magnet sticks it cannot be 316 and might be 304. If the magnet doesn’t stick it could be either 316 or cold worked 304, so heat the piece to about 800 °C, let air-cool and try again with magnet. If it sticks now its 304 SST.
Is 304 stainless steel a marine grade?
While stainless steel grades 304, 316 and duplex steels can all be used in marine applications, they do provide varying degrees of corrosion resistance and durability.
Is 304 food grade stainless steel?
The most common food grade stainless steel is Type 304. 304 grade stainless steel is so popular in the food industry because of its resistance to oxidization and corrosion. The chromium protects the product from oxidization or rust, whereas the nickel content rescues the food grade drum from corrosion.
Does 304 stainless steel attract magnets?
Wrought, austenitic stainless steels, such as 304 and 316, are generally regarded as non-magnetic in the annealed condition, i.e. they are not attracted significantly by a magnet. However, if they are cold worked they will be attracted to a permanent magnet.
Is all 316 stainless steel marine grade?
The current industry standard, however, is grade 316 (UNS S31600/S31603 – commonly termed “marine grade” stainless) which offers a solution to around 90% of marine applications.
