As a result of these properties small particles (approx. Does 304 stainless steel attract magnets?īoth 304 and 316 stainless steel possesses paramagnetic characteristics. However, an item of 316 stainless steel which has significant welding or machining may be sufficiently magnetic to produce a noticeable attraction when brought near a magnet. With its higher nickel composition range, 316 is considered the "most nonmagnetic" stainless steel. 304 is almost for sure to become magnetic after cold work such as pressing, blasting, cutting, etc. However, 300 series stainless is non-magnetic only after it is freshly formed. Is 304 grade stainless steel magnetic?Īll stainless steel is magnetic except austenitic stainless steel which is actually 300 series stainless such as 304 and 316. Like all ferromagnetic alloys, when heated to a high enough temperature–their Curie temperature–the ferritic stainless steels lose their ferromagnetism and become paramagnetic–that is, they do not retain their own magnetic field but continue to be attracted to external ones. A ferritic stainless like 430 stainless steel, on the other hand, is ferromagnetic. Austenitic stainless steels like 304 or 316 stainless are good examples of this. Some steels are only weakly magnetic, and some are not magnetic at all. The reason your refrigerator doesn't hold a magnet, according to Peter Eng, a physicist at the University of Chicago, is that different stainless steels contain different proportions of nickel (added to help keep steel from cracking and to allow the addition of more carbon, for strength). Why do magnets not stick to my stainless steel fridge? Duplex Stainless Steel such as grade 2205.Martensitic Stainless Steel such as grades 410, 420, 440.Ferritic Stainless Steels such as grades 409, 430 and 439.The following types of stainless steel are typically magnetic: Which types of stainless steel are magnetic? Is 304 or 316 more magnetic? From our experience 304SS small particles are more likely to be held in the flow than 316 SS particles due to its slightly more magnetic nature. This type of stainless steel is magnetic primarily because it contains large quantities of ferrite in its chemical composition, which is a compound of iron and other elements. Here our first part of KVM Tutorial is complete.Stainless steel grades 410, 420 and 440 – martensitic stainless steels.
