The process established in Phase II to extrude and warm draw a Tee section to .040 thickness in H-11 and PH15-7MO has proven to be reproduc ible. A container temperature at the linear surface of approximately 900 F is necessary in order to consistently obtain crack-free thin PH15-7MO extrusions. The use of a resistance type furnace for warm draw preheat in place of induction heating has much improved reliability. Author
