UNS N10276 is a tungsten-containing nickel-chromium-molybdenum-alloy with very low silicon and carbon content. The alloy has excellent corrosion resistance to most corrosive media in both oxidizing and reducing states. Excellent resistance to pitting corrosion......

Product characteristics1、Good resistance to oxidation of sulfur-containing gas2、Good mechanical properties at room temperature and high temperature3、Excellent high temperature oxidation resistance4、Good resistance to carbonizationDue to the controlled amou......

Nickel Alloy 625 is a face centered cubic crystal structure. After holding at 650 ℃ for a long enough time, carbon particles and unstable quaternary phase will be precipitated and transformed into stable Ni3 (Nb, Ti) orthorhombic lattice phase. After solution......

UNS N06600 is corrosion resistant to a wide range of corrosive media. The chromium composition gives the alloy better corrosion resistance under oxidizing conditions than nickel 99.2 (alloy 200) and nickel 99.2 (alloy 201, low carbon). Also, the higher nickel ......

Last week, MT Group held the annual mid-year meeting. 2022 is also a year full of changes and challenges for Mtsco. In the first half of the year, we changed our new office environment, held a business PK competition, and participated in Tube Dusseldorf after ......

How much do you know about seamless steel pipe? Seamless steel pipe is a kind of round, square, rectangular steel with hollow cross section and no seam around. Seamless steel pipe is made from ingots or solid billets that are perforated to make a burr pipe ......

Nickel is a ferromagnetic metal element with excellent properties such as corrosion resistance, high temperature resistance, oxidation resistance and good ductility. It is widely used in metallurgy, chemical industry, aerospace and other fields. It is an impor......

1. Folding Fake and inferior welded stainless steel pipes are easy to fold. Folding is a variety of fold lines formed on the surface of stainless steel pipes. This defect often runs through the longitudinal direction of the whole product.The reason for foldin......

Directly welded pipes: the use of small size model can avoid stress corrosion, hot cracks and deformation, and the welding current is 20% lower than that of high carbon steel. In order to ensure the ignition of the electric arc, the DC reverse connection is a......

In the process of manufacturing and using welded pipe, nondestructive testing to ensure weld quality is particularly important.  The common nondestructive testing methods for welded pipes are: ultrasonic testing, off-line magnetic flux leakage testing and edd......

Penetrant testing (abbreviated as PT) is a nondestructive testing method for inspecting surface opening defects based on the principle of capillary action. This method is one of the five conventional nondestructive testing methods and is a comprehensive scienc......

Radiographic testing (RT). Radiography (RT) is a nondestructive testing method that uses X-ray or g-ray to penetrate the test piece and film as the equipment for recording information. This method is the most basic and widely used non-destructive testing metho......

When there are brown rust spots on the surface of stainless steel pipe, people are surprised: they think that "stainless steel is not rusty, rusty is not stainless steel, maybe there is a problem with the steel".In fact, this is a one-sided wrong view of the l......

Based on the principle of electromagnetic induction, the nondestructive testing method is called nondestructive testing, which can nondestructive evaluate some properties of conductive materials and their workpieces by detecting the change of induced eddy curr......

Ultrasonic testing is mainly used to detect buried defects in butt welds and cracks on the inner surface of pressure vessel welds. It is also used to detect possible cracks in Pressure Vessel Forgings and high-pressure bolts.Ultrasonic testing can be divided i......

Austenitic stainless steel is softened by solid solution treatment. Generally, the stainless steel pipe is heated to about 950 ~ 1150 ℃ and kept warm for a period of time, so that the carbides and various alloy elements are fully and evenly dissolved in auste......

Welding: usually refers to the welding of metal. It is a forming method to connect two separated objects into one by heating or pressurizing, or both at the same time.Classification: according to the different heating degree and process characteristics in the ......

The function of heat treatment is to improve the material mechanical properties of steel pipe, eliminate residual stress and improve its cutting performance.According to different purposes of heat treatment, heat treatment process can be divided into two categ......

Skates are required in figure skating, synchronized skating, speed skating and short track events stipulated by the International Skating Union (ISU) and ice hockey events of the International Ice Hockey Federation (IIHF). What kind of steel is used for ice sk......

Superalloy (also known as heat-resistant alloy) is a metal material with long-time creep resistance, high endurance strength and high corrosion resistance under the simultaneous action of stress and high temperature (above 600 ℃). With excellent oxidation res......

Tension is a simple mechanical property test. Within the test gauge, the stress is uniform, the measurement of stress-strain and its performance indexes is stable, reliable and convenient for theoretical calculation. Through the tensile test, the most basic me......

Stainless steel can be divided into four categories according to its steel structure, namely austenitic stainless steel, ferritic stainless steel, martensitic stainless steel and AUSTENITIC FERRITIC duplex stainless steel. The following mainly analyzes the wel......

Weldability of metal materials refers to the ability of metal materials to obtain excellent welded joints under certain welding processes, including welding methods, welding materials, welding specifications and welding structure forms. If a metal can use more......

Last week, Jiaxing MT Stainless Steel held the annual year-end summary meeting. 2021 was an extraordinary year for international trade and steel industry. The global epidemic has not been alleviated, and China shoulders most of the production responsibility......
