When cast, steels similar to 304 and 316 stainless have small amounts of the magnetic phase referred to as ferrite in the microstructure. (Welds used for these materials also have small amounts of ferrite.) Depending on the amount of ferrite, stainless castings vary from slightly to substantially magnetic.

Cold drawn 304 (and to a lesser degree 316) is attracted to a magnet, but this has no effect on the corrosion resistance. Some of the most highly corrosion resistant stainless steels are strongly magnetic examples are the duplex and super duplex grades and highly alloyed ferritic grades such as 29-4C. Cold drawn 304 also has high tensile strength, but this is not due to the magnetic response both the magnetic response and the high strength are duFAQ 3:Magnetic Effects of Stainless SteelsWrought, austenitic stainless steels, such as 304 and 316, are generally regarded as non-magnetic in the annealed condition, i.e. they are not attracted significantly by a magnet. However, if they are cold worked they will be attracted to a permanent magnet.
CB-30 and 430 are strongly magnetic because they are predominantly ferrite. AISI 316 will seldom attract a magnet because it is essentially all austenite. Grade CF8M is slightly magnetic because, while predominantly austenite, it contains normally 5 20 percent ferrite. You may wonder why 316 and CF8M are so different if they are equivalent. Medical Applications of Stainless Steel 304 (UNS S30400)Aug 30, 2012 · For further information on this grade:Stainless Steel 304. Stainless Steel 304 - Properties used in Medical Devices. Stainless Steel 304 is regarded the world over as one of the most suitable materials for the manufacture of medical devices for all sorts of applications. In fact, it is the most common stainless steel used in the world today. Removing magnetism from 304 Stainless SteelSep 03, 2008 · The practical answer is that SS 304 is not strongly magnetic, but machining and cold working can make it somewhat magnetic. If you need a quantitative relationship between degree of magnetism vs. type & degree of machining, sorry, it's beyond my knowledge.
Stainless Steel IdentifiersUnderstanding the Various Types. While austenitic stainless steel is non-magnetic when annealed with a solution, certain cold worked grades are magnetic. Heat-based hardening will not work with these types of steel. Popular grades of austenitic stainless steel include 303, 304, 316, 310 and 321 grades. WHAT IS THE DIFFERENCE BETWEEN THE MAGNETIC To complicate matters further, the magnetic properties of these alloys depend on the alloy composition. Within the allowed ranges of variation of Ni and Cr, significant differences in magnetic properties may be observed for a given alloy. Practical implications for removal of stainless steel particles. Both 304 and 316 stainless steel possess What Stainless Steel Is Magnetic? - SizeMetalSep 25, 2018 · 316 stainless steel is an alloy steel that is less magnetic than the 304 grade. 316 is generally meant for harsher environments as well. In terms of cost, this will be more expensive than 304. If anyone is looking to install a magnetic stainless steel sheet, we recommend going with 304 especially if you are using it in a food or kitchen setting.
Magnetic Properties of 304 and 316 Stainless Steel Wire Mesh Basket Cable Tray. 304 stainless steel contains chromium (min. 18%), and nickel (min. 8%). It is an austenite steel and is only slightly responsive to magnetic fields. It also contains 18 20% chromium and 8-10.50% nickel, and lesser quantities of some other elements.
