API Specification 20E
mycommittees.api.orgAustenitizing temperatures shall not exceed 1700F (925C). Tempering temperatures for ASTM A193, Grade B7, ASTM A320, Grade L7, and Grade L43, and ASTM A540 Grade B23 shall not exceed 1300ºF (700ºC). Induction and direct-resistance heat treating processes can exceed these temperatures, causing potential metallurgical problems.

www.kljack.comA thermal process used to increase the hardness and strength of steel. It consists of austenitizing, then cooling at a rate sufficient to achieve partial or complete transformation to martensite. Tempering should follow immediately, and involves reheating to a temperature below the transformation range and then cooling at any rate desired.
