Can I re-temper A514/QT100 for increased toughness
Can I re-temper A514/QT100 for increased toughness
(OP)
We are developing an automotive drive plate that requires a failry ductile and tough material. The volume on the project is fairly low, so we are constrained to typical readily available plate material. A514/QT100 plate meets exceeds our requirements, but the concern is that the hardness is too great. Our requirements are min 70ksi Yield 85ksi Tensile with an elongation of >25%.
Can this material be tempered again to increase its ductility/toughness at a cost of some yield and tensile strength?
