304 questions.
Is 304 enough for a cleanroom?
Often, yes. It depends on your cleaning agents and contact time, so we ask first.
How is 304 different from 316L?
316L adds molybdenum for better resistance to chlorides and many acids.
Do I get a material certificate?
Yes, EN 10204 3.1 with every delivery.
