TENSILE TESTING – ELASTICITY / RESILIENCE
Low tensile strength
High tensile strength
HOW TO INCREASE STRENGTH
STRENGTHENING MECHANISMS
• Hardening by H/T-heat treatment
− H/T Martensitic steels like Sandvik 7C27Mo2
• Deformation hardening
− C/R Austenitic spring steels like Sandvik 11R51
• Grain size
− Duplex steels, C/R austenitic
• Precipitation hardening
− Sandvik 9RU10, Sandvik Nanoflex, tempering effect in Sandvik 11R51
• Solution hardening
− All stainless steels, Cr and Ni in iron
