What is a Standard Finish?“Standard” finishes are produced on an on-going basis. They are generally available off the shelf or can be obtained with a short lead-time. They are the finishes that are used for most stainless steel applications. Standard finishes are categorized as either “Mill” or “Polished”.“Mill” finishes are the least expensive finish option. There are both hot- and cold-rolled mi...

Stainless steel is generally highly resistant to attack from acids, but this quality depends on the kind and concentration of the acid, the surrounding temperature, and the type of steel. Type 904 is resistant to sulfuri acid at room temperature, even in high concentrations; types 316 and 317 are resistant below 10%; and type 304 should not be used in the presence of sulfuric acid at any concentr...
