Sandvik Bioline 1RK91 Strip steel
Categories: Metal; Ferrous Metal; Stainless Steel
Material Notes: Sandvik Bioline 1RK91 is a precipitation hardening stainless steel specifically designed for applications requiring high strength combined with good ductility in the final product and high formability in the as delivered condition. The strength is increased after ageing of the final product. The characteristics in general can be said to be a combination of properties of ordinary austenitic stainless and low alloyed ferritic steels. For example, elastic modulus, mechanical properties and thermal expansion are comparable to ferritic steels (such as low alloyed carbon steels or chromium steels) while corrosion resistance is more comparable to austenitic stainless steels.
  • Excellent mechanical properties; very high tensile strength and hardness levels can be achieved
  • Corrosion resistance comparable to ASTM 304L or ASTM 316L depending on condition
  • Retained mechanical properties at temperatures up to at least 400°C (750°F)
  • Very good relaxation properties
  • Good weldability
