Witryna17 lut 2024 · Toughness was flat using 1475-1525°F but higher temperatures led to a significant reduction in toughness, presumably due to grain growth. Therefore the balance leads us to an optimum of 1500-1525°F. Another steel that acts somewhat similarly is 52100 due to its relatively low carbon in solution.
