摘要：<span>201</span><span style="font-family:宋體;">不鏽鋼板與</span><span>304</span><span style="font-family:宋體;">不鏽鋼板如何區(qū)分</span> <p> <span>1</span><span style="font-family:宋體;">、</span> <span style="font-family:宋體;">規(guī)格：常用的不鏽鋼板材分為</span><span>201</span><span style="font-family:宋體;">和</span><span>304</span><span style="font-family:宋體;">兩種型號(hào)，實(shí)際是是成分不同，</span><span>304</span><span style="font-family:宋體;">質(zhì)量好一些，但價(jià)格貴，</span><span>201</span><span style="font-family:宋體;">差一些。</span><span>304</span><span style="font-family:宋體;">為進(jìn)口不鏽鋼板，</span><span>201</span><span style="font-family:宋體;">為國(guó)產(chǎn)不鏽鋼板。</span><span><br /> </span><span>2</span><span style="font-family:宋體;">、</span><span> 201</span><span style="font-family:宋體;">是含錳較高，表麵很亮帶有暗黑的亮，含錳較高容易生鏽。</span><span>304</span><span style="font-family:宋體;">含鉻較多，表麵呈現(xiàn)啞光，不生鏽。兩種放在一起就有比較了。*重要的就是耐腐蝕性能不同，</span><span>201</span><span style="font-family:宋體;">的耐腐蝕性能很差，所以價(jià)格就要便宜很多。又因?yàn)?lt;/span><span>201</span><span style="font-family:宋體;">含鎳低，所以價(jià)格比</span><span>304</span><span style="font-family:宋體;">的低，於是耐腐蝕性能就不如</span><span>304</span><span style="font-family:宋體;">的了。</span><span><br />

style="font-family:宋體;">之間的區(qū)彆就是含鎳的問題。而且</span><span>304</span><span style="font-family:宋體;">的價(jià)格現(xiàn)在都比較貴，一般都要接近</span><span>50000</span><span style="font-family:宋體;">一噸，但</span><span>304</span><span style="font-family:宋體;">的話起碼可以保證在使用過程中不會(huì)生鏽。</span><span>4</span><span style="font-family:宋體;">、</span><span> 201</span><span
