Conventional Standards of Pipes & Tubes

Stainless steels may be classified by their crystalline structure into four main types: austenitic, ferritic, martensitic and duplex. These stainless steels possess austenite as their primary crystalline structure (face centered cubic).

Regular steel (non-stainless) would be considered "ferritic" because the room-temperature microstructure is comprised of a mix of ferrite and pearlite. Ferrite is soft and ductile, while pearlite is hard and brittle. As the overall content of carbon increases, the proportion of pearlite becomes higher and the bulk strength increases.

We can find two major categories of pipe In the steel pipe market: welded pipe and seamless pipe. Here we provide you with more information in detail to tell you how to choose suitable type between them
