Heat Treatment Parameters: stainless_steel
Heat treatment process parameters for engineering alloys — annealing, normalizing, quench-and-temper, precipitation hardening, carburizing, and stress relief. Covers carbon steels (1020/1045/1080), alloy steels (4130/4140/4340/8620/52100), tool steels (H13/D2/M2), stainless steels (304/316/17-4PH/15-5PH), aluminum alloys (2024/6061/7075), Ti-6Al-4V titanium, and Inconel 718. Per ASM Handbook Vol.4A/4B, ASTM A255, AMS 2770.
