Stress Relaxation in Bending of AISI 301 Type Corrosion-Resistant Steel Strip

Source

Bending stress relaxation experiments were made on AISI 301 type corrosion-resistant steel strip. Test data obtained on standard, tapered cantilever beam test specimens at temperatures ranging from 23 to 93°C (73 to 200°F)2 over a time period of 20 000 h (2 years, 4 months) are compared with force relaxation data obtained on two complex clamp spring designs made from this material. Good correlation is obtained between the two sets of data. The effects of stress relief heat treatment and anisotropy on stress relaxation were also studied. Finally, the stress relaxation behavior of 301 type corrosion-resistant steel strip is compared to that of CA762 (12 percent nickel-silver). Both materials, if properly heat treated, retain better than 98 percent of the initial stress value after 20 000 h at 93°C (200°F) in the “elastic” range.
