    A METALLOGRAPHIC CORRADING AGENT SHOWING MARTENSITIC STAINLESS STEEL STRUCTURE

    • HF+HNO3 water solution can be used for corroding of metallographic sample of martensitic stainless steel, corroding efficacious is the same as its of 4% nitric acid alcohol solution, corroding speed is quick and corroding test surface is clear, similar discoloration made on test surface can be avoided when FeCl+HCl water solution is applied.
