In the past, we may have said no, but after extensive testing, we've determined our metal stamps can in fact be used on stainless steel. Something to note, though, is all stainless steel stamping blanks are not made equal. To ensure you have the proper grade of stainless steel for stamping, purchase your stainless steel stamping blanks from Beaducation as all of our stainless steel blanks can be stamped. Please also note that stamping on stainless steel is not for beginners, as it takes a lot of practice and skill to perfect, even the most seasoned stampers have difficulty stamping on stainless steel. The more detailed the design stamp, the more difficult it will be to stamp. If you do decide to stamp on stainless steel, make sure you have a sturdy stamping surface like a stamping post, you can learn how to make a stamping post with our detailed instructions. If you're just getting started with stamping, we recommend you opt for softer metals like aluminum blanks and pewter blanks, you'll have much more success with clear impressions and less possibility of double stamping impressions.
