Stainless Steel Sheet 304/304L Finish No. 4

Type 304/304L is the basic “18-8” chromium-nickel stainless steel. It combines excellent mechanical properties with remarkable resistance to many corrosive agents encountered in industrial and domestic use. Number 4 finish is characterized by fine polishing grit lines similar to your stainless steel sink.

Specifications:

ASTM A240

Applications:

Used in dairy, beverage, and food industries. Used in parts which see most concentrations of acetic, nitric, citric acids, organic and inorganic chemicals, crude and refined oils. Because it is non-magnetic it is used instruments measuring magnetic and electrical properties.
