When selecting between S7 and A2 tool steel, the fundamental difference is: S7 is engineered for superior toughness and impact resistance, whereas A2 offers excellent wear resistance. Understanding this is crucial for choosing the optimal grade for your applications. Both A2 and S7 are cold-work tool steels; however, S7 is primarily classified as a shock-resisting […]

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,
