304不锈钢因其卓越的耐腐蚀性往往被用着内层(即直接与水接触),201不锈钢因为耐腐蚀性较差,不能用着内层,往往被用在保温水箱的外层。但是201304价格低廉,往往会被一些不良商家冒充304使用,用201不锈钢制作的不锈钢水箱使用寿命极短,往往1-2年就能被水腐蚀,给使用者留下安全隐患。

304 stainless steel because of its excellent corrosion resistance is often used in the inner layer (that is, direct contact with water), 201 stainless steel because of poor corrosion resistance, can not use the inner layer, is often used in the outer layer of the insulation water tank. But 201 than 304 the price is low, often will be used by some bad businesses pretend to be 304, with the stainless steel water tank made of 201 stainless steel service life is very short, often 1-2 years can be corroded by water, leaving safety risks to users.

不锈钢水箱用到的304201不锈钢,表面通常为亚光。所以我们通过肉眼看、手触摸的方式鉴别。肉眼看304不锈钢具有很好的光泽发亮,手触摸很顺滑;201不锈钢则颜色发暗 没有光泽,触摸有比较粗糙不光滑的感觉。另外将手沾湿水,分别触摸2种不锈钢板,触摸后304板上的水渍手印比较容易擦除,201不容易擦除。  

Stainless steel tank used in 304 and 201 stainless steel, the surface is usually matte. So we identify it by the naked eye and touch it by the hand.naked eye see 304 stainless steel has a good luster, hand touch is very smooth; 201 stainless steel color is dark without luster, touch has a relatively rough not smooth feeling. In addition, touch the hand wet with water and touch two kinds of stainless steel plates respectively. Touch the water stain fingermark on the 304 board is relatively easy to wipe, and 201 is not easy to erase.

201是含锰较高,表面很亮带有暗黑的亮,含锰较高容易生锈。304含铬较多,表面呈现哑光,不生锈.两种放在一起就有比较了。最重要的就是耐腐蚀性能不同,201的耐腐蚀性能很差,所以价格就要便宜很多.又因为201镍低,所以价格比304的低,于是耐腐蚀性能就不如304的了。

201 is high in manganese, the surface is very bright with dark bright, high in manganese is easy to rust.304 contains more chromium, the surface is matte, do not rust. The two kinds are put together to make a comparison. The most important thing is that the corrosion resistance is different, the 201 corrosion resistance is very poor, so the price is much cheaper. And because 201 contains low nickel, so the price is lower than 304, so the corrosion resistance is not as good as that of 304.
