At MBNS we mainly use following materials for fabrication:
High Alloy steels alloyed high percentage with of Nickel (2-20%) and Chromium (0,5-18%) specifically elements to develop corrosion resistance or extreme temperature stability
(low) Alloy steels alloyed frequently Chromium-Molybdenum used grades P2, P12, P11, P22, P22L, P21, P21L, P5, P9 and P91
Stainless steels (chromium, chromium-nickel, and chromium-manganese-nickel stainless steel) alloyed with Titanium, Molybdenum, Nobium, according ASTM grades of group SA 240/240M, according SAE designation series 300 (austenitic chromium-nickel stainless steel), 400 (ferritic and martensitic chromium stainless steel)
