Duplex Stainless Steel Applications in the Oil and Gas Industry

In the past few decades, the severity of corrosion in the oil and gas industry has increased year by year. Because the offshore oil industry continues to push oil exploration deeper, it leads to higher pressure conditions and harsher environments. In addition, advanced technologies have increased the total capacity of domestic reservoirs, thereby increasing the […]

Selection of stainless steel materials in desalination plant

Desalination plants are known to be very corrosive because of the high temperatures in the environment. Austenitic stainless steels of the previous 300 series are often the preferred materials for desalination plants. In cases where higher corrosion resistance is required, typical material solutions have exceeded the higher alloyed austenite grades of the 300 series stainless steels such […]

The origin of nickel metal

Nickel is a silvery white metal with magnetic properties and good plasticity. With good corrosion resistance, nickel is nearly silver-white, hard and malleable, and has a ferromagnetic metallic element that is highly polished and resistant to corrosion. After dissolved in nitric acid, it is green. Mainly used for alloys (such as nickel steel and nickel […]

Introduction of the role and classification of basic metals

The base metals usually refer to industrial non-ferrous metals, mainly copper, lead, nickel, zinc, and tin. In addition to copper, all base metals react with hydrochloric acid to form hydrogen. Because of their ease of extraction and large quantities, they are much less expensive than precious metals. The contracts for copper, lead, nickel and zinc are traded […]

The difference between ERW, DOM, and seamless steel pipe

ERW pipe (resistance welded pipe) The name ERW is because such stainless steel pipes involve certain types of welding processes such as spot welding and seam welding. Seam welding is usually used when manufacturing round, square and rectangular stainless steel pipes. The stainless steel band is unwound from the coil and trimmed to control the width and adjust […]

Performance difference between 304 and 304L stainless steel

304 stainless steel is the most widely used austenitic stainless steel, and it is also called 18-8 stainless steel, because this kind of stainless steel contains 18% chromium and 8% nickel. 304 physical properties of stainless steel: Density: 0.803g / cm 3 Resistivity: 72microhm-cm (20 C) Specific heat: 0.50kJ / kg-K (0-100 C) Thermal conductivity: 16.2 W / MK (100 […]
