渗铝是在高温下将铝渗入钢铁工件表面形成铁铝合金层的冶金和化学热处理工艺。它使钢铁的抗高温氧化能力提高10倍以上，使用温度可比镀锌、镀锡提高300℃以上，防腐蚀寿命是热镀锌制件的5倍以上，它在大气环境中的耐腐蚀时间可长达50年。同时，可耐硫化物、熔盐和氨等各种化学?
Aluminizing is the metallurgical and chemical heat treatment process of infiltrating aluminum into the surface of steel parts at high temperature to form an iron-aluminum alloy layer. It makes the high-temperature oxidation resistance of steel more than 10 times, the use of temperature than galvanized, tin increased by more than 300 ℃, anti-corrosion life is hot-dip galvanized parts more than 5 times its corrosion resistance in the atmospheric environment can be Up to 50 years. At the same time, can be resistant to sulfide, molten salt and ammonia and other chemical?
