Stainless Steel AISI316 contains Molybdenum for more corrosion resistance, but much more expensive; Stainless Steel AISI304 doesn’t contain Molybdenum, and it is cheaper choice in cost.
304 material does not contain molybdenum, and the nickel content is 8% or more; 316 material contains molybdenum 2.0% or more, nickel 10% or more. The difference between them is corrosion resistance, but they are the same strength .
Normally, for marine field hardware , SS316 is widely used ; For other outdoor environment , SS304 is most suggested .
The Chemical Composition of Stainless Steel 304/3016/316L :
To ensure the material is 100% correct , the strict quality control and testing are necessory.
Every manufacturing steps should be comform to the standard production rules ,that is the base that every products from us are reliable.
