Stainless steel commonly react with certain substance that probably will produce some defect whether inner or outer surface. This material contains small casting defects‚ mainly shrinkage cavities‚ due to the manufacturing process. Commonly in industries related to piping system‚ stainless steel pipelines and cylinder tubes are equipment or object that frequently used in our removable insulation installation. In most industrial nowadays‚ stainless steel pipes are frequently exposed to high temperatures

pros and cons of weathering steel:: "Weathering" means that due to their chemical compositions‚ these steels exhibit increased resistance to atmospheric corrosion compared to unalloyed steels. This is because the steel forms a protective layer on its surface under the influence of the weather. The corrosion-retarding effect of the protective layer is produced by the particular distribution and concentration of alloying elements in it. The layer protecting the surface develops and regenerates
