Duplex Stainless Steel Pipe  is stainless steel with approximately 50% of ferrite and austenite phases in the solid solution structure. It not only has good toughness, high strength and excellent resistance to chloride corrosion but also resists pitting corrosion and crystal resistance. Corrosion, especially stress corrosion resistance in chloride ion environment. Duplex Stainless Steel Pipe The marine environment is complicated. In addition to considering the effects of various forces caused by various natural factors in the design of marine engineering, factors such as seawater corrosion and microbial corrosion must be considered. In offshore engineering fields such as offshore platforms, artificial islands, and oil and gas exploration and production platforms, a large number of steel materials are used to manufacture various structural parts and equipment. Due to its high strength and excellent stress corrosion resistance, duplex stainless steels are particularly suitable for

Austenite is a lamellar microstructure of steel. It is usually a non-magnetic solid solution in which a small amount of carbon is solid-dissolved in rhenium-Fe. The austenite name is from the British metallurgist William Chandler Roberts-Austen.   Austenitic Stainless Steel Pipe  has good plasticity, low strength, some toughness, and no ferromagnetism. Because austenite is a face-centered cubic, the tetrahedral gap is larger, which can hold more carbon. Ferrite is an interstitial solid solution in which carbon is dissolved in α-Fe. It has a body-centered cubic lattice, and its carbon dissolving ability is very low. It can dissolve only 0.0008% of carbon at normal temperature, and its maximum carbon dissolving ability is 0.02% at 727 ℃. It is called ferrite or alpha solid solution, and it is expressed by alpha or F. Alpha is commonly used in phase icons, and F is commonly used in the text. Austenite with a sub-eutectoid a component is firstly co-precipitated to form ferrite. Stai

Stainless steel is a metal material stainless steel refers to steel that is resistant to erosion by weakly corrosive media such as air, steam, and water, and chemically corrosive media such as acid, alkali, and salt. It is also called stainless acid-resistant steel. Steels that are resistant to erosion by weakly corrosive media are often referred to as stainless steels, and steels that are resistant to chemical media erosion are referred to as acid-resistant steels. Because of the difference in chemical composition between the two, the former is determined to be resistant to chemical media erosion, and the latter is generally equal. It is stainless. The corrosion resistance of stainless steel depends on the alloying element \ x0d contained in the steel. The basic alloy elements of stainless steel are nickel, molybdenum, titanium, niobium, copper, nitrogen, etc., in order to meet the requirements of various applications on the structure and function of stainless steel, stainless steel

As a  Welded Stainless Steel Pipes Manufacturer China , share the information with you. Stainless steel is a metal material. Stainless steel refers to steel that is resistant to erosion by weakly corrosive media such as air, steam, and water, and chemically aggressive media such as acid, alkali, and salt. It is also called stainless acid-resistant steel. The steel that is eroded is called stainless steel, and the steel that is resistant to chemical media is called acid-resistant steel. Because of the difference in chemical composition between the two, the former is determined to be resistant to chemical media, and the latter is generally stainless.
