镀锌板和不锈钢有什么区别？

What is the difference between galvanized plates and stainless steel?

镀锌板就是铁片上刷一层金属锌防腐，有冷镀和热镀，时间长表面的锌是会掉的，铁就会被腐蚀，所以镀锌板价格相对来说低，不锈钢就不用防腐，所以不锈钢价格就贵了，不锈钢在200-300，只有些特殊材料在200-300度低温回火，不过温度太低一般没有太大的变化镀锌板在高温下（200度、300度）下表层的锌会被慢慢烘烤掉。

Galvanized plate is a layer of metal zinc anticorrosion, cold plating and hot plating, long time surface zinc will fall, iron will be corroded, so galvanized plate price is relatively low, stainless steel need not anticorrosion, so stainless steel price is expensive, stainless steel in 200-300, only some special materials in 200-300 degrees low temperature tempering, but the low temperature is generally not too much change galvanized plate at high temperature (200 degrees, 300 degrees) surface zinc will be slowly baked off.

不锈钢种类很多，镀锌板只是在钢板或者铁板表层电镀了一次金属锌。镀锌板本身是普板，做了表面加工而已。不锈钢板是防腐耐酸的合金板。看你做什么用途，200-300度不算是高温，相对比较便宜的不锈钢430板价格应该比同等规格的镀锌板价格贵2倍。相比较于镀锌板价格和不锈钢价格，主要看用于哪里。

There are many kinds of stainless steel, galvanized plate just plated on the surface of steel plate or iron plate.The galvanized plate itself is a general board, just surface processed.Stainless steel plate is an acid-resistant alloy plate.Look at what you do, the 200-300 degrees is not a high temperature, and the relatively low price of the cheaper stainless steel 430 plate should be twice higher than the galvanized plate of the same specification.Compared to the galvanized plate price and stainless steel price, mainly to see where to be used.

不锈钢是通过加入微量元素达到改变钢材组分的目的，实现防腐功能的。镀锌板是在普通钢板表面镀锌，以牺牲锌的方式实现防腐目的的。200度、300度对金属来说都不成问题，看环境气氛，会有一些极微小的影响，但需很长时期才有变化。

Stainless steel is through the addition of trace elements to change the purpose of steel components, to achieve anticorrosion function.Galvanized plates are galvanized on the surface of ordinary steel plates to achieve anticorrosion purposes at the expense of zinc.Both 200 degrees and 300 degrees are not a problem for the metal. Looking at the environmental atmosphere, there will be some very small effects, but it will take a long time to change.
