Stainless Steel 316 ID Kit (1542C) sorts SS 316 from SS 304


Part No. 1542C

When you specify 316 stainless steel, and you pay for 316 stainless steel; how do you know you really have 316 stainless steel? Mixing this desirable material with common 304 can result in a variety of nasty problems.

Metal Testing Kit

Supplier’s certifications and importer's promises are not enough. Testing alloy content with undeniable, foolproof, reliable kits from Koslow Scientific provides you with peace of mind. Order the 316 Stainless Steel ID Kit and test it yourself! For over 50 years companies from pharmaceutical to aerospace have relied on Koslow kits. No need for expensive XRF equipment. No need to file off samples to mail to metallurgical testing labs. A chemical spot test is a diagnostic test that is performed by the electro-spot method. Verify your stainless steel 316 incoming and outgoing stock. Use the quality testing solutions that have been ordered by engineers, fabricators, welders and scrap metal dealers. Sensitive and interference-free chemical color tests detect the alloying components. A color develops as a result of a chemical reaction and, generally, the intensity of the color can be used to estimate the amount of alloying component present. Spot tests are more straightforward, faster and cheaper than chemical analysis. The density of color reactions are correlated to nominal composision.  This is usually sufficient for alloy identification differentiation and verification. The 1542C includes a metal sample to be used as a testing reference. Working with the 316 Stainless Steel ID Kit Calibration Standard will vividly demonstrate a positive result.

Testing For Stainless "L" Grades

In addition to the “Moly Test,” the 1542C also contains a low carbon test which can detect SS316L from ordinary SS316 or SS304L from ordinary SS304. This unique chemical spot test requires the steel samples to be heated prior applying the Electro-Spot Method.

Great product!
by Jason, May 12,2017

I started using the 316 alloy ID test kit the same day I received it and it is a great product. The instructions were very clear and the contents of the kit marked well so that using it the first time was very easy, and the results very consistent! I would definitely reorder from Koslow in the future!

316 ID Kit Review
by Jordan Ehr, Mar 21,2017

I had ordered test kit 1542C. This kit was being used to determine if a sample was 316 stainless or 304. Overall I think the kit was easy to use and the instructions were clear. The baseline sample of the 316 stainless was nice. It would have been also good to include a sample of 304 stainless to be able to tell the difference between the two. Luckily I had a known sample of the 304 to test. With that being the only issue I saw I would definitely recommend this product. Koslow also was very impressive with the responsiveness of the customer service team and were able to work with me to get everything in a timely manner.

Great Kit
by Derek, Jan 03,2017

I wanted to follow up our purchase of the Stainless Steel 316 ID kit number 1542C. We were very pleased with the timely manner in which it was shipped and arrived even over the holiday. We had a chance to use it as soon as it came in, and with some help from a video on your web site everything work as needed. Given the quality of service I was given when trying to get this ordered, how quickly it arrived, and how well it preformed I would definitely recommend this to anyone looking for this type of product. As far as areas that could be improved I could not think of anything.

Thank You,

We have you Stainless Steel 316 ID kit. The kit works great we have used it on several occasions in the past 3 years and it has saved us the 3-5 times the cost of the kit. I would definitely recommend this product to someone else. My suggestion would be setting up either a label system on the outside of the kit or sending out an email reminder when the chemicals are expiring. We have ordered your Power up kit but a reminder for all of the chemicals would still be great (and would help with regular sales of your chemicals.) Thank you.
