生产卷帘门可用不锈钢种类有哪些?

不锈钢有非常多的材质,但是常用材质有 304/304L/316/316L/321/310S 410/420/420J1/420J2/430/ 201/202 关于怎么鉴别不锈钢材质的优劣,如果个人鉴别不锈钢具体是哪种材质是没法鉴别的,必须通过化学分析才行。
Stainless steel has many materials, but the commonly used materials are 304 / 304L / 316 / 316L / 321 / 310S 410 / 420 / 420J1 / 420J2 / 430 / 201 / 202. As for how to identify the advantages and disadvantages of stainless steel, if you can't identify the specific material of stainless steel, you must pass chemical analysis.

有一些比如400系列与300系列的鉴别可以通过磁性鉴别,400系列一般是有磁性的,300一般没有磁型号 301 延展性好,用于成型产品。也可通过机械加工使其迅速硬化。焊接性好。抗磨性和疲劳强度优于304不锈钢。 型号 302 耐腐蚀性同304,由于含碳相对要高因而强度更好。 型号 303 通过添加少量的硫、磷使其较304更易切削加工。
For example, the identification of 400 series and 300 series can be through magnetic identification. 400 series is generally magnetic, 300 is generally not magnetic, and model 301 has good ductility and is used for molding products. It can also be hardened rapidly by machining. Good weldability. The wear resistance and fatigue strength are better than 304 stainless steel. The corrosion resistance of model 302 is the same as that of 304. Because the carbon content is relatively high, the strength is better. Model 303 is easier to cut than 304 by adding a small amount of sulfur and phosphorus.

型号 304 通用型号;即18/8不锈钢。GB牌号为0Cr18Ni9。 型号 309 较之304有更好的耐温性。 型号 316 继304之后,第二个得到更广泛应用的钢种,主要用于食品工业和外科手术器材,添加钼元素使其获得一种抗腐蚀的特殊结构。由于较之304其具有更好的抗氯化物腐蚀能力因而也作"船用钢"来使用。
Model 304 general model; 18 / 8 stainless steel. The GB brand is 0Cr18Ni9. Model 309 has better temperature resistance than 304. Model 316 is the second most widely used steel after 304. It is mainly used in food industry and surgical equipment. Adding molybdenum makes it obtain a special corrosion-resistant structure. Because it has better chloride corrosion resistance than 304, it is also used as "marine steel".
SS316则通常用于核燃料回收装置。18/10级不锈钢通常也符合这个应用级别。[1] 型号 321 除了因为添加了钛元素降低了材料焊缝锈蚀的风险之外其他性能类似304。 400 系列 铁素体和马氏体不锈钢 型号 408 耐热性好,弱抗腐蚀性,11%的Cr,8%的Ni。
SS316 is usually used in nuclear fuel recovery units. Grade 18 / 10 stainless steel generally meets this application grade. [1] The performance of model 321 is similar to that of 304 except that the risk of material weld corrosion is reduced due to the addition of titanium. 400 series Ferritic and martensitic stainless steel model 408 has good heat resistance and weak corrosion resistance, 11% Cr and 8% Ni.
型号 409 更廉价的型号(英美),通常用作汽车排气管,属铁素体不锈钢(铬钢)。 型号 410 马氏体(高强度铬钢),耐磨性好,抗腐蚀性较差。 型号 416 添加了硫改善了材料的加工性能。 型号 420 "刃具级"马氏体钢,类似布氏高铬钢这种更早的不锈钢。也用于外科手术刀具,可以做的非常光亮。
Model 409 the cheapest model (British and American), usually used as automobile exhaust pipe, is ferritic stainless steel (chromium steel). Model 410 martensite (high strength chromium steel), good wear resistance and poor corrosion resistance. Model 416 adds sulfur to improve the processability of the material. Model 420 "cutting tool grade" martensitic steel, similar to the earliest stainless steel such as Brinell high chromium steel. It is also used for surgical tools, which can be made very bright.
型号 430 铁素体不锈钢,装饰用,例如用于汽车饰品。良好的成型性,但耐温性和抗腐蚀性要差。 型号 440 高强度刃具钢,含碳稍高,经过适当的热处理后可以获得较高屈服强度,硬度可以达到58HRC,属于更硬的不锈钢之列。更常见的应用例子就是"剃须刀片"。常用型号有三种:440A、440B、440C,另外还有440F(易加工型)。
Model 430 ferritic stainless steel for decoration, such as automotive accessories. Good formability, but poor temperature resistance and corrosion resistance. Model 440 high strength cutting tool steel, with slightly higher carbon content, can obtain higher yield strength after appropriate heat treatment, and the hardness can reach 58hrc. It is one of the hardest stainless steels. The most common application example is "razor blade". There are three common models: 440A, 440b, 440C, and 440f (easy to process).
