不锈钢方管性能
Properties of Stainless Steel Square Pipe
金属在大气中都可与氧气反应在表面形成氧化膜,普通碳钢上形成的氧化铁会继续进行氧化,使锈蚀不断扩大,最终形成孔洞。
Metals can react with oxygen in the atmosphere to form oxide film on the surface. Iron oxide formed on common carbon steel will continue to oxidize, which will expand the corrosion and eventually form holes.
这可以利用油漆或耐氧化的金属进行 电镀来保护碳钢表面,但这种保护层只是一种薄膜,如果保护层被破坏,下面的钢便又开始锈蚀。
This can be done by electroplating paints or oxidation-resistant metals to protect the surface of carbon steel, but the protective layer is only a thin film. If the protective layer is damaged, the steel below begins to rust again.
不锈钢管是否被锈蚀与钢中的铬含量有关,钢中的铬含量达到12%时便不容易被腐蚀。 而好的201不锈钢管中铬含量达到13%以上,304不锈钢管中铬含量达到18%以上。
Whether stainless steel pipes are corroded or not depends on the chromium content in the steel. When the chromium content in the steel reaches 12%, it is not easy to be corroded. The content of chromium in good 201 stainless steel pipe is more than 13%, and that in 304 stainless steel pipe is more than 18%.
