StainlessSteels
Corrosion resistance for aggressive environments
High-chromium steels that form a passive oxide layer, providing corrosion resistance in wet, chemical and stringent hygienic environments.
Introduction
Stainless steels contain enough chromium to form a stable passive layer on the surface, providing corrosion resistance in wet, saline, chemical and food-processing environments.
Each family—martensitic, austenitic or ferritic—combines hardness, mechanical strength, formability and chemical resistance differently, allowing the right alloy to be selected for each service condition.
Aços Formosa supplies stainless steels as raw material for components, shafts, machined parts, tools and equipment that must withstand prolonged contact with aggressive media.
