Sanmac® 4571 — Alleima
1 MPa = 1 N/mm 2 a) R p0.2 and R p1.0 correspond to 0.2% offset and 1.0% offset yield strengths, respectively. b) Based on L 0 = 5.65 √S 0 where L 0 is the original gauge length and S 0 the original cross-sectional area.. Impact strength. Due to its austenitic microstructure, Sanmac ® 4571 has very good impact strength both at room temperature …
