S7 Tool Steel Heat Treatment Guide S7 tool steel is typically heat-treated by preheating to 1200\u20131250\u00b0F (649\u2013677\u00b0C), austenitizing at about 1725\u00b0F (940\u00b0C), air quenching for sections up to about 2.5 in. (63.5 mm), and applying immediate double tempering. For most cold-work tooling, S7 is commonly tempered at 400\u2013500\u00b0F (204\u2013260\u00b0C), producing a typical working hardness of
