304L不锈钢管的元素含量 C≤0.03 Ni8.00~12.00 Cr18.00~20.00,Mn<=2.0 Si<=1.0 S<=0.030 P<=0.035。
304L不锈钢管18Cr-8Ni-低碳 作为低C的304钢,在一般状态下,其耐蚀性与304钢相似,但在焊接后或者消除应力后,其抗晶界腐蚀能力优秀;在未进行热处理的情况下,亦能保持良好的耐蚀性,使用温度-196℃~800℃。 应用于抗晶界腐蚀性要求高的化学、煤炭、石油产业的野外露天机器,建材耐热零件及热处理有困难的零件。
304L stainless steel pipe 18Cr-8Ni- low carbon is a low-C 304 steel. Under normal conditions, its corrosion resistance is similar to that of 304 steel, but after welding or stress relief, its resistance to intergranular corrosion is excellent; In the case of heat treatment, it can also maintain good corrosion resistance, and the use temperature is -196℃~800℃. It is applied to outdoor machines in the chemical, coal, and petroleum industries that require high grain boundary corrosion resistance, heat-resistant parts for building materials, and parts with difficult heat treatment.
