Material Points

  • Most common grades in this industry are 304 (12), 316L (9), and 420 (3)— parentheses indicate number of affected areas, as a starting point for quoting and material procurement.
  • Wear parts (edges, liners, conveyors) consider hardness, not just corrosion resistance (11/16 hits).
  • Chloride ions and salts are the most common sources of corrosion (pitting, crevice corrosion) (8/16 hits).
  • Thickness range 1–12 mm: Thin plates are mostly formed parts (considering bend back-arc and deep drawing cracks), thick plates are mostly welded structures (considering heat input and sensitization).

Common questions

What type of stainless steel is used most in the food processing industry?
How many parts are we looking at?
What's the most common grade?
Which part is prone to issues?
For what kind of material and temperature?
Thickness range in the list is 1–12 mm. For thin plates, consider bending and surface finish; for thick plates, welding and structural strength. Values may vary by equipment manufacturer for the same location, review your drawing or operating conditions.
