Below is a list of Austenitic Stainless Steel manufacturers from Philadelphia, Pennsylvania. As the most common type of stainless steel, austenitic stainless steel has the highest ratio of chromium and can be used in mild, harsh and corrosive environments. Accounting for 70% of the total stainless steel production, the term “austenitic” refers to the crystalline structure of the stainless steel, which allows for higher ductility, tensile strength and lower yield stress than typical carbon-based steels.
