How can I check difference in between 304-316 and 202? Please advise.

Hi, Harvinder. 3xx series stainless steel is non-magnetic (well, almost non magnetic); 2xx series stainless steel is essentially as magnetic as plain steel.
Of course, if you have the money, a "scrap sorter" hand-held XRF machine will instantly tell you exactly what each piece of unknown metal is -- but you're talking about $25,000.
Regards,

We have a few SS316 materials fabricated and machined. There is no
scope for cutting a sample to check the chemical composition. Also we
are not in a position to go for handheld tester to test these
materials as they are simply not available at the place of material.
Is there any other method by which I can check the material.
Thanks,

i know of a way to tell the difference tween 304 and 316. this method has been used in recycling for years. its called "spark test" . with an angle grinder grind 304 look at sparks they will fork out at the end of their flight. 316 will spark but each spark will stay intact till the end of its flight. try it out its cheap and better for the environment.

I am into the construction and interiors line and have a problem: how would we be able to check to see if a kitchen basket of stainless steel is made of 202 or 304 SS? (If possible, some way where even a lay-man could check for him / herself) There are just too many instances of customers being taken for a ride. Thanks!

Ed. note: that is answered above, Kiran. 2xx stainless is highly
magnetic, 3xx is essentially non-magnetic. Good luck.

DEAR SIR
WE ARE LOOKING FOR THE CHEMICAL TO DETECTION OF MOLYBDENUM IN
STAINLESS STEEL . WE HAVE FOUND SOME COMPANY SELL TOTAL KIT BUT WE
NEED ONLY THE CHEMICAL. DOES IT CALLED ELECTROLYTE?
WE WOULD BE GRATEFUL IF ANYONE ADVICE WHAT IS THE EXACT COMMERCIAL
NAME OF THAT CHEMICAL TO FIND.
IT WOULD BE BETTER IF WE GET IN INDIA.

I believe that Lee Gearhart's initial response answers your question, Mostafiz. However, I am not able to source the ASTM SP550 spec he mentions. Good luck.

necessary degrease and dry. DDD Tuck

reagent to tell the difference between 304 and 316. PETER KEMP
September 18, 2009 The Koslow Scientific Company has a spot test kit called 304 vs. 316 Kit is an easy method to sort 316 from 304 stainless steel that we have been using this kit for years. Lauren Keane
