Solution Annealing is an on-site heat treatment service which alters the metallurgical structure of a material to change its mechanical or electrical properties. Typically, this process is used to decrease metal crack sensitivity of aged material that needs to be returned to a weldable state. Solution Annealing will affect secondary carbides precipitated during extended high temperature service by increasing ambient temperature ductility and fracture toughness. This process involves air quenching post heat application.
