The Pros And Cons Of 304 Vs 316 Stainless Steel

The addition of nitrogen additionally improves resistance to pitting corrosion and will increase mechanical strength. Thus, there are numerous grades of stainless steel with various chromium and molybdenum contents to go well with the environment the alloy should endure. Grade 316 has especially better resistance to salt and chloride pitting. Pitting corrosion can happen when stainless-steel alloys, similar to grade 304 stainless-steel, come into contact with salt-wealthy sea breezes and seawater.

Applications For 316 Stainless Steel

The chromium content material have to be 18% or extra to be 304 stainless. After a 500 ton press squeezes the nickel it modifications the distribution of the nickel. The same is true where the die cuts the stainless growing the likelihood A240 304L Stainless steel plate that rust will eventually occur there. All chrome steel is magnetic besides austenitic stainless-steel which is actually 300 series stainless corresponding to 304 and 316.

  • An increase of chromium content material improves the corrosion resistance of stainless steel.
  • It’s corrosion and oxidization resistance paired with durability and how easy it is to clean has made stainless-steel one of the safest materials within the food preparation and storage industries.
  • Stainless metal has become one of the common supplies present in kitchens and the meals trade at present.
  • From meals processing crops to massive, industrial kitchens to your personal kitchen at house, stainless steel is ever current.

400 collection stainless (ie. martensitic chrome steel) is magnetic. Stainless steel containing more nickel (310 and 316 grades) is extra likely to stay non-magnetic after cold work. Some 3D printing suppliers have developed proprietary stainless steel sintering blends for use in speedy prototyping. One well-liked chrome steel grade utilized in 3D printing is 316L stainless-steel.

However, 300 collection stainless is non-magnetic only after it’s freshly formed. 304 is almost for certain to become magnetic after chilly work corresponding to pressing, blasting, cutting, etc. Initially the cold work causes the stainless to pick up foreign particles similar to free iron. Then at some spots the metallic crystal structure changes from austenite to martensite.


Where a galvanic couple forms, one of many metals within the couple becomes the anode and corrodes sooner than it will alone, whereas the opposite turns into the cathode and corrodes slower than it will alone. Stainless metal, as a result of its superior corrosion resistance relative to most other metals, similar to carbon steel and aluminium, becomes the cathode, accelerating the corrosion of the anodic metallic. An example is the corrosion of aluminum rivets fastening stainless steel sheets in contact with water.
