The fundamental difference between S7 and A2 tool steel is that S7 is engineered for excellent toughness and impact resistance, and A2 offers excellent wear resistance. In terms of classification, S7 belongs to impact-resistant steel among cold-work tool steels; A2 belongs to hardenable medium alloy cold-work steels. 1. Core Distinctions: S7 vs. A2 1.1 Toughness […]

When selecting materials for your tooling, it is important to understand the differences between grades like O1 and O2 tool steel. Both are common in the O-series of oil-hardening tool steels, but their characteristics can affect your manufacturing. The Bottom Line Up Front For factory managers and engineers comparing O1 and O2:  O1 tool steel is a well-documented,
