a) Rp0.2 and Rp1.0 correspond to 0.2% offset and 1.0% offset yield strength, respectively.
b) Based on L0 = 5.65 ÖS0 where L0 is the original gauge length and S0 the original cross-section area.
Impact strength
Due to its austenitic microstructure, Sandvik 3R64 has very good impact strength both at room temperature and at cryogenic temperatures.
Tests have demonstrated that the steel fulfils the requirements according to the European standards prEN 13445-2 (UFPV-2) ( (min. 60 J (44 ft-lb) at -270 oC (-455 oF)) and prEN 10216-5 (min. 60 J (44 ft-lb) at -196 oC (-320oF).
