Testing 304 And 316 With Simple Magnet Test Youtube Old school magnet test on 304 steel and 316 stainless steel to show the difference in iron content. stainless steel contains different levels of iron and thi. Testing stainless steel for magnetic properties. for those interested in testing the magnetic properties of stainless steel, a simple and effective method is to use a refrigerator magnet. if the magnet sticks to the surface, the stainless steel is likely of the ferritic or martensitic variety. if the magnet does not adhere, the steel is most.
Testing Magnet Mpco Magnets Dear mr. crowley, here is a spot test to sort 304 ss from 316 ss. make sure the area you test is clean and flat, if possible. 1. add 1 drop concentrated hydrochloric acid and allow it to react for 1 minute. 2. add 1 drop 6% sulfurous acid, wait 30 seconds. 3. a black stain indicates 316 ss. Acid testing is one test that will separate 304 and 316 grades of stainless steel. hydrochloric acid attacks 304 grade very rapidly and produces gas, but attacks 316 grade only very slowly. there are also proprietary test chemicals, such as decapoli and avesta 960 which detect the presence of molybdenum, a component of 316 grade, but not of 304. 316 stainless steel: similar to 304, it is typically non magnetic but can become weakly magnetic under certain conditions. 310 stainless steel: used in high temperature applications. generally non magnetic but can show weak magnetism when cold worked. read this guide to learn more about 304 and 316 stainless steel: 304 vs 316 stainless steel. 2. Magnetic, spark, hardness and acid identification tests for austenitic, martensitic and ferritic stainless steels. stainless steels can be hard to identify. the different types can be distinguished by methods as. for full table with sulfuric and hydrochloric acid test rotate the screen!.

Grade 304 stainless steel is non magnetic or exhibits weak magnetism. if the bottle shows strong magnetic properties, it is likely not genuine grade 304 stainless steel. 3. copper sulfate test. remove the oxide layer from the steel surface, add a drop of water, and wipe it with copper sulfate. if there is no color change, it is likely stainless. If it has an austenite structure, then it will not be magnetic. in other words, ferritic grades of stainless steel are magnetic, such as grades 409, 430, and 439. martensitic stainless steels in grades 410, 420, and 440 are also magnetic. austenitic steel grades are non magnetic, such as grades, 3.3, 304, 310, and 321.
