HEAT TREAT FOR 6150 COLLET
HEAT TREAT FOR 6150 COLLET
(OP)
WE HAVE BEEN MAKEING COLLETS OUT OF 6150. THE QUESTION CAME UP HOW TO HEAT TREAT 6150 FOR THE COLLET TO HAVE SOME FLEX. I HAV SOME OLD NOTES TO HEAT TREAT TO Rc42-46. DO I NEED TO GIVE THE HEAT TREATER ANY OTHER INSTRUCTIONS?

Higher strength will give higher hardness and better fatigue properties.
Lower strength will be softer and have better toughness.
You need to choose a balance.
As quenched 6150 should be 59-65 RC.
So tempering to 42-46 RC is a medium strength condition, it sounds reasonable.

The reason you want to provide explicit processing requirements to your heat treat vendor is so that they will use the same procedure every time, which in turn should give you a consistent product. Take a look at pages 20-21 of this Jorgensen Steel handbook. It provides some reference data for oil quenched 6150 steel tempered at various temperature levels. In addition to specifying the tempered hardness range, you should also specify a standard that should be used for controlling the heat treat process and equipment. One such standard commonly used in aerospace is AMS 2759/1. However, you should ask your heat treat vendor which standard they prefer to work to.
