Stainless steel pipes can be classified into two types: seamless pipes and welded pipes. Seamless pipes are produced by cold drawing or cold rolling, with high dimensional accuracy and surface quality, suitable for high-demand applications such as petrochemicals and medical equipment. Welded pipes a

Metal corrosion problems are widespread in many areas of the national economy, such as oil and gas, petrochemical, transportation, machinery manufacturing, etc. It can be said that corrosion problems exist wherever metal materials are used. Metal materials are damaged by the action of surrounding media, which is called metal corrosion.

Silicon The content of silicon in austenitic stainless steel is generally below 0.8% - 1.0%. As an alloy element, silicon content ranges from 2% to 7% depending on its use. Silicon is an element that strongly forms ferrite.
