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 metal quenching processes such as stainless steel pipes
The so-called metal quenching is a method of rapidly reducing the metal back to room temperature after heat treatment (e.g., annealing) in order to prevent the significant change in the microstructure of the metal during the cooling process. Quenching results in an increase in the degree of hardening of the steel at the same temperature […]
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 […]
Corrosion characteristics of metals such as metal
When most metals come into contact with certain substances in air or water, chemical changes occur that reduce the integrity of the metal. This process is called corrosion. Among them, materials such as oxygen, sulfur, and salt can cause metal corrosion, and metals with good corrosion resistance are represented by stainless steel plates. When the metal […]
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 […]
The development and manufacture of steel
Steel is one of the most widely used metals in the modern world. It’s cheap, powerful and incredibly versatile. In the world, the annual production volume of steel is about 750 million tons, and steel is the second largest volume production product after cement. Steel is completely recyclable and requires only relatively little energy to produce. […]
Differences between carbon steel and stainless steel
Selecting the right type of steel for your project is one of the most important decisions. Before deciding individual material grades, it is also first necessary to decide which type of steel to use, such as carbon steel or stainless steel. This article will discuss the difference between carbon steel and stainless steel. Corrosion resistance The most […]
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 […]
What is the difference and connection between metal hose and bellows?
Metal hose and bellows compensator main performance similarities and differences: Only air tightness a bellows is better than metal hose. Because the bellows are made of a monolithic material, the metallic hose is a flexible member that is wound with a stainless steel band, so that the problem of slight air leakage cannot be prevented. However, with […]
