Sandvik 11R51 is an austenitic stainless steel with excellent spring properties that in most cases fulfil demands regarding corrosion resistance, mechanical strength, fatigue and relaxation properties. Compared with the standard grade Sandvik 12R11, Sandvik 11R51 offers:

• Higher tensile strength and tempering effect

• Higher relaxation resistance, especially at elevated temperatures

• Higher fatigue strength

• Better corrosion resistance, due to the addition of molybdenum

Applications
Sandvik 11R51 is suitable for springs and other high strength components in the mechanical, electronics and computer industries. It is a very good spring material that in most cases fulfils demands regarding corrosion resistance, mechanical strength, fatigue and relaxation properties, especially in dynamic loaded applications when better fatigue resistance is required.
