Sandvik 11R51 is an austenitic stainless steel alloyed with molybdenum. The grade is characterized by high tensile strength and high resistance to corrosion, fatigue and relaxation.

Compared to most other steels of ASTM 302 type (for example Sandvik 12R10/gusab T302), Sandvik 11R51 offers:

  • Higher tensile strength and tempering effect
  • Higher relaxation resistance, especially at elevated temperatures
  • Higher fatigue strength
  • Better corrosion resistance, through the addition of molybdenum

Service temperature: -200 to 300°C (-330 to 570°F).
