   不锈钢分很多种,其中的有磁xing的被人们称为不锈铁,其实,它们也属于不锈钢。
    不锈铁是不锈钢的yi种。不锈钢为什么不sheng锈,那是因为内部含有铬元素.整ge不锈钢体系分为四大lei:第yi:马氏体不锈钢:直接添jia铬,磁xing,热处lixing的不锈钢.热处li可以shengchengcui火gao强du马氏体,并具bei针状wei观zu织.第er:铁素体不锈钢:直接添jia铬,磁xingdan不jin行热处li的不锈钢,铁素体相往往cun在着.第三:奥氏体不锈钢:含有铬,nie元素,非磁xing,不jin行热处li的不锈钢,奥氏体经cui火后,变的非常jian韧,延展xing好,且强du相礲ei,第四lei:沉淀硬化不锈钢(双相不锈钢):这yilei钢即包含马氏体,也有奥氏体的cun在.jia格方面,不锈钢普bian比不锈铁贵。俗称的不锈铁就是非奥氏体的不锈钢,它们具有yi定的磁xing即不锈铁指的是有磁xing的不锈钢,不锈铁的金相zu织是铁素体和马氏体,通常所说的不锈钢的金相zu织是奥氏体.民间称马氏体不锈钢和铁素体不锈钢即为“不锈铁”.
   不锈铁与不锈钢相比主要是在于是fu含nie!不锈铁yiban是指日本的SUS430,国内为1Cr17,主要化学cheng分为:C:<0.12,Si:<0.75,Mn<100,P:<0.035,S<0.030,Ni:<0.60,Cr:16.00-18.00为铁素体不锈钢。
  不锈铁是含铬而不含nie的,也cheng为Cr不锈钢,就有yi定的fangfu蚀nengli!不锈铁不是俗语,通俗ren为具有铁磁xing的不锈钢,我ren为主要指1Cr17(铁素体)系列、1Cr13(马氏体)系列,而Fe以奥氏体形式cun在shi不具铁磁xing。文中以Ni/Cr区分容yi误会,sui然它们导致了Fe的同素异构。danFe、Ni为铁磁,Cr为顺磁xing。gaoxingnengruan磁材料1J系列很多是Ni基。
  而不锈钢是ji含铬又含nie的,由于nie属于较稳定元素,那么它的抗fu蚀nengli自然要比不锈铁强很多!
  由于nie的jia格较贵,所以从cheng本上不锈钢要gao于不锈铁,zaijia上抗fu蚀nengli的差异,不锈钢jia格比不锈铁gaochu1/4~1/3 (仅gongcan考)
  bian别: 由于nie是抗磁xing元素,yiban比较简单的分bian方法是看是fu具有较强的磁xing,即用磁铁laixi引!文章lai源:(http://www.yfyd360.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!
