COLD-RESISTANT STEEL REBAR

摘要

The sensitivity of hot-rolled and thermomechanically strengthened rebar towards brittle failure in the temperature range from +20 to -70°C is evaluated; the dependence of failure energy at -70°C on rod diameter is studied. The change in rebar mechanical properties under the effect of temperature is studied. Recommendations for manufacture in EVRAZ ZSMK of cold-resistant rebar class As500S according to TU 14-1-5543 are developed from research results.
