This improves fracture resistance, but it also limits maximum hardness and abrasive wear resistance.\n      <\/p>\n\n      <h2>Why Toughness Matters in Cracking and Fracture Failure<\/h2>\n      <p>\n        Cracking often starts from sharp corners, impact-loaded edges, holes, notches, or areas exposed to repeated thermal cycling.\n      <\/p>\n      <p>\n        In high-carbon, high-chromium steels, large carbides improve abrasive wear resistance but can also serve as crack initiation sites. This is why grades such as D2 and D3 are strong choices for wear, but not always the best choice for heavy impact or sudden fracture.\n      <\/p>\n      <p>\n        High-toughness tool steels use a different balance. They reduce carbide-related brittleness and rely more on matrix strength, ductility, and shock resistance.\n      <\/p>\n\n      <h2>High Toughness Tool Steel Selection Table<\/h2>\n\n      <div class=\"aobo-table-wrap\">\n        <table class=\"aobo-table\">\n          <thead>\n            <tr>\n              <th class=\"ds-text\">Failure \/ Working Condition<\/th>\n              <th>Recommended Grades<\/th>\n              <th class=\"ds-text\">Why These Grades Fit<\/th>\n            <\/tr>\n          <\/thead>\n          <tbody>\n            <tr><td class=\"ds-text\">Repeated impact at room temperature<\/td><td>S7, S5, S1<\/td><td class=\"ds-text\">S-series steels are designed for shock resistance.
