Our shop reworked 4340 tube stock (AMS 6414) and created an area of undersize outer diameter.
It was proposed to chrome coat the affected surface and machine again to proper finish OD.
Would there be any deleterious effect? Hydrogen embrittlement, etc?
Is there a better process to build up or...
Samples of 2024-T351 had a post heat treatment at 550 F for 3 hours (oven cool) for the purpose of stress relieving.
Did this time and temp have a detrimental effect on the properties?
