Corrosion)比较敏感。减少这种敏感性需要额外增加2-3%的钼，这样316不锈钢就诞生了。此外，这些额外的钼还可以降低某些热有机酸的腐蚀。316 食品饮料行业标准材料几乎全是316不锈钢。由于钼元素世界范围内的短缺及316 不锈钢中含镍量较高，因此316 不锈钢的价格比304 不锈钢要贵。由不锈钢表面沉积腐蚀引起的一种现象叫做点腐蚀，这是由于不锈钢材质缺氧而不能形成氧化铬保护层。尤其在小型阀门中，点腐蚀几乎很少发生，因为阀板上出现沉积的可能性很小。在各种类型的水介质(饮用水、海水、河水、蒸馏水、锅炉水、等)中，抗腐蚀性能方面304 不锈钢与316不锈钢的基本一样，但是介质中氯离子的含量非常高时，316 不锈钢就比较适合。</p><p>　　在一般情况下，抗腐蚀性能方面304 不锈钢与316 不锈钢的区别不大，可在某些条件下差别很大，需根据具体情况分析。阀门用户应该心中有数，他们一般会根据介质的情况选择容器和管道的材质，不建议向用户推荐材料。</p><p> </p> </div> </div> <div class="cp"> <div class="cptab"> 相关产品<div
