The main difference between seamless steel pipe and welded steel pipe are molding process. General welded steel pipes such as water pipes, is generally flat plate by bending and welded together after

Seamless steel pipes for heat exchange are intended for heating or cooling process fluids, they are for example suitable for closed circuit cooling of electrical equipment using demineralised water an

The continuous casting method produces round billets mainly for the production of seamless steel tubes of different calibers. The round billet perforation relies on two inclined rollers to rotate the

While duplex stainless steel tube only comprises a small percentage of the global stainless steel market, it has a range of benefits when compared to traditional austenitic stainless steel pipe and fe

The concept of duplex stainless alloys was discussed as early as the 1920s. However, production of the first duplex alloys did not begin until the 1930s.These earliest duplex alloys were mostly limite

Duplex stainless steels[1][2][3][4][5] are a family of stainless steels. These are called duplex (or austenitic-ferritic) grades because their metallurgical structure consists of two phases, austenite

Stainless Steel 316 Pipe is an austenitic stainless steel grade pipe that has good resistance to chloride ion corrosion stress cracking. For this reason, the pipe is used in marine and sea water appli

When contractors select materials for metal pipework, stainless steel tube is often overlooked due to its price compared to other options such as PVC for applications such as wastewater and chemical t

Martensitic stainless steel can be divided into two categories: martensitic chromium steel and martensitic chromium-nickel steel according to different chemical compositions; according to different st

It was discovered in the early 20th century and its name comes from the famous metallurgist Oscar Marx. The formation process of martensitic stainless steel can be simply understood as rapid cooling a

Martensitic stainless steel alloys were discovered and subsequently industrialized in 1912 by Harry Brearley of the Brown-Firth Research Laboratory in Sheffield, England, while searching for a corrosi

The matrix is ​​a martensitic structure (body-centered cubic or cubic), which is magnetic and its mechanical properties can be adjusted through heat treatment. The American Iron and Steel Institute is
