Overview
Austenitic, ferritic, martensitic and duplex stainless grades covering the full spread of general-purpose and specialised corrosion-resistant steels.
IMS handles stainless steel as both prime material and as arisings recovered from industrial processing. Material is sorted and segregated by grade, so it returns to the melt as a known specification rather than a mixed stream.
