Both A2 and A4 grades come in three property classes: 50 (soft), 70 (cold-worked) & 80 (high-strength) – the most common of which is the 70 class which is cold drawn” from bar stock. These classes have different mechanical properties. For example, A2-70 has a tensile strength of 700 Nmm-2 and 450 Nmm-2 proof stress. sac heart sacramento
