Laboratory analysis and expertise of stainless steel and other stainless alloys

Stainless alloys…

Stainless alloys or stainless steels are steels to which an outer layer of chromium oxide has been applied. To comply with the EN 10088-1 European standard, steel is classified as stainless if it contains at least 10,5% chromium and less than 1,2% carbon in weight.

There are different categories of stainless steels, the most common are:

  • X2CrNi18-9 (AISI 304L or A2): used to make everyday products
  • X2CrNiMo17-12 (AISI 316L or A4): used in the chemical, pharmaceutical, oil and food industries.
  • X8Cr17 (AISI 430): used to made household appliances, sinks…
  • X6CrTi12 (AISI 409): used to make automobile exhausts, furnaces… 

Chemical analysis of stainless alloys: one of FILAB’s specialties
