0.08 C, 2.00 Mn, 0.045 P, 0.030 S, 0.75 Si, 18.00/20.00 Cr, 12.00/15.00 Ni, Up to 2.25 B, 0.10 N
A family of 18% chromium austenitic stainless steels balanced with increased nickel versus T304 and a boron addition (up to 2.5%) which imparts a high thermal neutron absorption cross section. This family of ASTM A887 Grade “B” alloys display the same refined boride microstructure and boride uniformity present in Micro-Melt NeutroSorb PLUS family of alloys. The Micro-Melt NeutroSorb family of alloys have higher ductility, impact strength and fracture toughness compared to their ASTM A887 Grade “B” counterparts produced by cast/wrought processing and lower ductility, impact strength and fracture toughness compared to their Micro-Melt NeutroSorb Plus ASTM Grade “A” counterparts.
Specifications: ASTM A887 Grade "B" Alloys
