This acknowledges your inquiry of February 23, 1980, concerning the close tolerance forming of stainless steel. Using cyo-forming methods with PH 17-7, a tolerance nearly ten times greater than the required tolerance by your firm has been achieved.
Attached for your reference is a complete article pertinent to your request. Also we would like to invite you as well as your staff to come here and observe the process. In am sure this will further help you attain your objectives in conducting the study.
Sincerely,
Briggs Aircraft Corp.
