[MW:3304] Re: stamping on material

HI AL
most of clients refuse using the hard stamp specially for stainless steel materials, sometimes paint stencile is used.
go to ASME II SA 20 ( PARAGRAPH: MARKING ) TO SEE SOME LIMITATION FOR THE HARD STAMPING


BEST REGARDS...

Dear ,  Punching is only for the traceability & identification , few codes accept hard punching in terms of criticality & application criteria. impression marks must not in depth means should not affect thickness and should not create any undue stress

ASME VIII  Div 1 , Subsection A  - Part UG -  clause UG - 10 -General requirements -  enlighten more

Thanks & Best Regards,
