304L不锈钢板的用途 
304L不锈钢的发展,已使304L不锈钢的耐蚀性、外观、加工性、强度等特性远远超过其它材料,而且,不锈钢的许多表面处理法,可以取得丰富多彩的颜色及形状,这为不锈钢的发展作出很大的贡献。

316L不锈钢与304L不锈钢的区别和辨别 
现在最常用的两种不锈钢304316(或对应于德/欧标的1.4308,1.4408),316304在化学成分上的最主要区别就是316Mo,而且一般公认,316的耐腐蚀性更好些,比304在高温环境下更耐腐蚀。所以在高温环境下,工程师一般都会选用316材料的零部件。但所谓事无绝对,在浓硫酸环境下,再高温度也千万别用316!不然这事可就出大了。学机械的人都学过螺纹,还记得为了防止在高温情况下螺纹咬死,需要涂抹的一种黑乎乎的固体润滑剂吧:二硫化钼(MoS2,从它就得出了2点结论不是:[1]Mo确实是一种耐高温的物质(知道黄金用什么坩埚熔吗?钼坩埚!)。[2]:钼很容易和高价硫离子反应生成硫化物。所以没有任何一种不锈钢是超级无敌耐腐蚀的。说到底,不锈钢就是一块杂质(不过这些杂质可都比钢更耐腐蚀^^)较多的钢,是钢就可以和别的物质反应。
