Heat Treat of 3Z Valve Piston

PDF Version Also Available for Download.

Description

To improve the processing of 3Z valve pistons in LF7 assemblies, material qualities are being investigated. After a review of the fracture toughness curve, it was noted that a change of a few degrees variation from the 900 F called for by the drawing would affect the fracture toughness of the product. After this observation it was decided to determine how close to the 900 F the parts were heat-treated. The subsequent study indicated that Federal Manufacturing & Technologies (FM&T) equipment held the product at 900 F {+-} 1.8 F.
