　　一、 不銹鋼是什么鋼？

　　1、 What is stainless steel?

　　不銹鋼是鋼的一個種類，鋼是指含有碳（C）量在2%以下的稱之為鋼，大于2%是鐵。鋼在冶煉過程中加入鉻（Cr）、鎳（Ni）、錳（Mn）、硅（Si）、鈦（Ti）、鉬（Mo）等合金元素改善了鋼的性能使鋼具有了耐腐性（即不上銹）就是我們常說的不銹鋼。

　　Stainless steel is a type of steel, which refers to steel containing less than 2% carbon (C) and more than 2% iron. Adding alloying elements such as chromium (Cr), nickel (Ni), manganese (Mn), silicon (Si), titanium (Ti), molybdenum (Mo), etc. during the smelting process improves the properties of steel and gives it corrosion resistance (i.e. no rust), which is commonly known as stainless steel.

　　二、為什么不銹鋼有不同的鋼號？

　　2、 Why are there different grades of stainless steel?

　　不銹鋼通常被分為201、202、301、304、309s、310s、410、420、431等多種型號。其中，201、202、301、304、309s、310s屬于奧氏體不銹鋼，不含有磁性，可耐多種介質(zhì)腐蝕。410、420、431則屬于馬氏體不銹鋼，具有磁性、強(qiáng)度高，但塑性和可焊性較差。其中硫磷含量是一很重要指標(biāo)，碳素結(jié)構(gòu)鋼和優(yōu)質(zhì)碳素結(jié)構(gòu)鋼就是根據(jù)它劃分的：硫，磷含量皆不超過0.04％的鋼，稱為優(yōu)質(zhì)鋼；硫含量不超過0.03％，磷含量不超過0.035％的鋼稱為高級優(yōu)質(zhì)鋼；硫磷含量各不超過0.025％的鋼稱為特級質(zhì)量鋼。

　　Stainless steel is usually divided into various types such as 201, 202, 301, 304, 309s, 310s, 410, 420, 431, etc. Among them, 201, 202, 301, 304, 309s, and 310s belong to austenitic stainless steel, which does not contain magnetism and can withstand corrosion from various media. 410, 420, and 431 belong to martensitic stainless steel, which has magnetism and high strength, but poor plasticity and weldability. The sulfur and phosphorus content is an important indicator, and carbon structural steel and high-quality carbon structural steel are classified based on it: steel with sulfur and phosphorus content not exceeding 0.04% is called high-quality steel; Steel with sulfur content not exceeding 0.03% and phosphorus content not exceeding 0.035% is called high-grade high-quality steel; Steel with sulfur and phosphorus content not exceeding 0.025% is called premium quality steel.

　　不銹鋼在冶煉過程當(dāng)中，由于加入合金元素品種不同，不同品種加入量的不同。其特性也是不同的，為了加以區(qū)別則冠上了不同的鋼號，下面是常見裝飾用不銹鋼不同鋼號“合金元素”含量表僅供參考：200系列：鉻-鎳-錳奧氏體不銹鋼300系列：鉻-鎳奧氏體不銹鋼301：延展性好，用于成型產(chǎn)品。也可通過機(jī)速硬化。焊接性好?？鼓バ院推趶?qiáng)度優(yōu)于304不銹鋼。302：耐腐蝕性同304，由于含碳相對要高因而強(qiáng)度更好。302B：是一種含硅量較高的不銹鋼，它具有較高的抗高溫氧化性能。303：通過添加少量的硫、磷使其較削加工。303Se：也用于制作需要熱鐓的機(jī)件，因為在這類條件下，這種不銹鋼具有良好的可熱加工性。304：即18/8不銹鋼。GB牌號為0Cr18Ni9。309：較之304有更好的耐溫性。

　　During the smelting process of stainless steel, the amount of alloying elements added varies depending on the type of alloy element added. Their characteristics are also different, and in order to distinguish them, different steel grades are labeled. The following is a table of "alloy element" content for common decorative stainless steels of different steel grades for reference only: 200 series: chromium nickel manganese austenitic stainless steel 300 series: chromium nickel austenitic stainless steel 301: good ductility, used for forming products. It can also be hardened by machine speed. Good weldability. Wear resistance and fatigue strength are superior to 304 stainless steel. 302: Corrosion resistance is the same as 304, and its strength is better due to its relatively higher carbon content. 302B: It is a stainless steel with a high silicon content, which has high resistance to high temperature oxidation. 303: By adding a small amount of sulfur and phosphorus, it can be processed more efficiently. 303Se: It is also used to make parts that require hot forging, as this stainless steel has good hot workability under such conditions. 304: 18/8 stainless steel. The GB grade is 0Cr18Ni9. 309: Compared to 304, it has better temperature resistance.

　　304L：是碳含量較低的304不銹鋼的變種，用于需要焊接的場合。較低的碳含量使得在靠近焊縫的熱影響區(qū)中所析出的碳化物減至最少，而碳化物的析出可能導(dǎo)致不銹鋼在某些環(huán)境中產(chǎn)生晶間腐蝕（焊接侵蝕）。304N：是一種含氮的不銹鋼，加氮是為了提高鋼的強(qiáng)度

　　304L: It is a variant of 304 stainless steel with lower carbon content, used for welding applications. The lower carbon content minimizes the precipitation of carbides in the heat affected zone near the weld, which may lead to intergranular corrosion (welding erosion) of stainless steel in certain environments. 304N: It is a nitrogen-containing stainless steel, and nitrogen is added to improve the strength of the steel
