Pipes made of 0Cr19Ni10Ti
Thread Content
Our company has a pipeline that transports vulcanizing agent (dimethyl disulfide). The original design pipeline material is 0Cr18Ni10Ti. The pipeline material purchased by the purchasing department is 0Cr19Ni10Ti. I would like to ask all experts, can this material be used? What is the difference between it and 0Cr18Ni10Ti in terms of sulfur corrosion resistance and welding performance?
There is no big problem. If 0Cr18Ni10Ti can be used, then 0Cr19Ni10Ti can also be used, the effect is just slightly worse.
It can also be used, but before construction, the designer should find a design change order so that it can be easily checked during use and maintenance after delivery.
There are differences in the grades of 0Cr18Ni10T and 0Cr19Ni10Ti, but the product ingredients are basically the same. Considering the cost, the precious metal content in steel plants is always at the lower limit. So feel free to use it.
They should all belong to the 321 series, no problem
