Steel grades
Each grade has its own page with chemical composition, equivalent designations and the full list of products in stock.
Acid-resistant
Austenitic with molybdenum – resistant to pitting and crevice corrosion; for chemicals, processing and chloride environments.
Austenitic stainless
Chromium-nickel without molybdenum – the standard choice for structures, food service and interiors.
Heat-resistant
Higher chromium and silicon – retain strength and scaling resistance at high temperatures.
Ferritic
Chromium without nickel – cheaper, magnetic, good where atmospheric corrosion resistance matters.
