S7 and A2 are both air-hardening tool steels<\/a>, but they serve different tooling needs. S7 <\/a>is best for impact, chipping, or cracking. A2 is preferable for abrasive wear, edge rounding, or loss of cutting accuracy.<\/p>\n\n\n\n

S7 uses a lower-carbon, lower-chromium design. It sacrifices some of A2’s wear resistance but gains toughness. This is why S7 is used where fracture is a bigger risk than gradual wear.<\/p>\n\n\n\n
