   不銹鋼分很多種，其中的有磁性的被人們稱為不銹鐵，其實，它們也屬于不銹鋼。
    不銹鐵是不銹鋼的一種。不銹鋼為什么不生銹，那是因為內部含有鉻元素.整個不銹鋼體系分為四大類:第一:馬氏體不銹鋼:直接添加鉻,磁性,熱處理型的不銹鋼.熱處理可以生成淬火高強度馬氏體,并具備針狀微觀組織.第二:鐵素體不銹鋼:直接添加鉻,磁性但不進行熱處理的不銹鋼,鐵素體相往往存在著.第三:奧氏體不銹鋼:含有鉻,鎳元素,非磁性,不進行熱處理的不銹鋼，奧氏體經淬火后,變的非常堅韌,延展性好,且強度相當高,第四類:沉淀硬化不銹鋼（雙相不銹鋼）:這一類鋼即包含馬氏體,也有奧氏體的存在.價格方面，不銹鋼普遍比不銹鐵貴。俗稱的不銹鐵就是非奧氏體的不銹鋼，它們具有一定的磁性即不銹鐵指的是有磁性的不銹鋼，不銹鐵的金相組織是鐵素體和馬氏體，通常所說的不銹鋼的金相組織是奧氏體．民間稱馬氏體不銹鋼和鐵素體不銹鋼即為“不銹鐵”.
   不銹鐵與不銹鋼相比主要是在于是否含鎳！不銹鐵一般是指日本的SUS430,國內為1Cr17,主要化學成分為:C:<0.12,Si:<0.75,Mn<100,P:<0.035,S<0.030,Ni:<0.60,Cr:16.00-18.00為鐵素體不銹鋼。
  不銹鐵是含鉻而不含鎳的，也成為Cr不銹鋼，就有一定的防腐蝕能力！不銹鐵不是俗語，通俗認為具有鐵磁性的不銹鋼，我認為主要指1Cr17(鐵素體)系列、1Cr13(馬氏體)系列，而Fe以奧氏體形式存在時不具鐵磁性。文中以Ni/Cr區分容易誤會，雖然它們導致了Fe的同素異構。但Fe、Ni為鐵磁，Cr為順磁性。高性能軟磁材料1J系列很多是Ni基。
  而不銹鋼是既含鉻又含鎳的，由于鎳屬于較穩定元素，那么它的抗腐蝕能力自然要比不銹鐵強很多！
  由于鎳的價格較貴，所以從成本上不銹鋼要高于不銹鐵，再加上抗腐蝕能力的差異，不銹鋼價格比不銹鐵高出1/4~1/3 （僅供參考）
  辨別： 由于鎳是抗磁性元素，一般比較簡單的分辨方法是看是否具有較強的磁性，即用磁鐵來吸引！文章來源：（http://www.saltwaterland.com）
Stainless steel is divided into many kinds, of which the magnetic is known as stainless steel, in fact, they also belong to the stainless steel.
Stainless steel is a kind of stainless steel. Why stainless steel does not rust, it is because the chromium containing stainless steel inside. The whole system is divided into four categories: First: martensitic stainless steel: directly add chromium, magnetism, heat treatment of stainless steel. Heat treatment can generate high strength quenched martensite, and microstructure with acicular ferrite stainless steel. Second:: the addition of chromium stainless steel, but not magnetic heat treatment, the ferrite phase exists. Third: austenitic stainless steel containing chromium, nickel, non-magnetic, without a heat treatment of austenitic stainless steel, after quenching, become very tough, good ductility, and the strength is very high, fourth categories: precipitation hardening stainless steel (duplex stainless steel): this kind of steel contains martensite, austenite. There is the price of stainless steel, stainless iron is generally expensive. Commonly known as the stainless iron is non austenitic stainless steel, they have the magnetism of the stainless iron is magnetic stainless steel, stainless iron microstructure is ferrite and martensite, commonly referred to as the stainless steel microstructure is austenite. Folk said martensitic stainless steel and iron element stainless steel body is "stainless iron".
Stainless iron and stainless steel is mainly depends on whether or not containing nickel! Stainless iron generally refers to the Japanese SUS430, the domestic 1Cr17, the main chemical components are: C:<0.12, Si:<0.75, Mn<100, P:<0.035, S<0.030, Ni:<0.60, Cr:16.00-18.00 for ferritic stainless steel.
Stainless steel iron chromium and nickel free stainless steel, also called Cr, have certain corrosion resistance! Stainless iron is not a saying, the popular think of a ferromagnetic stainless steel, I think the main refers to the 1Cr17 (Tie Suti) series, 1Cr13 (martensite) series, and Fe in the presence of austenitic form does not have iron magnetism. In this paper, Ni/Cr to distinguish easily misunderstood, even though they make the allotropism Fe. However, Ni and Fe are ferromagnetic, and Cr is paramagnetic. High performance soft magnetic material 1J series is a lot of Ni based.
Both chromium and nickel containing stainless steel, due to the relatively stable elements of nickel, then corrosion resistance of natural to stainless iron much better than!
As the price of nickel is more expensive, so from the cost of stainless steel is higher than stainless steel, coupled with the differences in corrosion resistance, stainless steel prices higher than the stainless steel 1/4~1/3 (for reference only).
Identification: as a result of nickel is an anti magnetic elements, the general comparison of the resolution is to see whether it has a strong magnetic, that is, with the magnet to attract!
