Ergste 9.9200GA Steel

Steel name: Ergste 9.9200GA
Diagram No.: 2729
Chemical composition in weight %: <0.030% C, 0.20% Si, 12.00% Cr, 2.00% Mo, 8.90% Ni, 1.60% Ti, <0.030% N
Steel group: Stainless steels
Properties: Ergste 9.9200GA is a precipitation hardenable 12% chromium nickel steel with outstanding corrosion resistance and impact toughness. Despite high strength this quality can be formed relatively well. By appropriate cold forming / heat treatment is a hardness of max. 51 HRC* to reach.
Applications: Surgical instruments (e.g. drills). Cutting instruments (e.g. rasps).
Reference: Not shown in this demo version.
