Use international chemical element symbols and symbols of the country to represent chemical components, and Arabic letters to represent component content: Such as: China, Russia 12CrNi3.
The development and progress of my country's stainless steel industry is relatively late. Since the founding of the People's Republic of China and before the reform and opening up, the demand for stainless steel in my country is mainly used in industry and defense. .
It has good formability and good weldability, and can be used as an ultra-high-strength material in the nuclear industry, aviation and aerospace industries. According to the composition, it can be divided into Cr series (400 series), Cr-Ni series (300 series), Cr-Mn-Ni (200 series), heat-resistant chromium alloy steel (500 series) and precipitation hardening series (600 series)..
Most of the requirements for use are to maintain the original appearance of the building for a long time. When determining the type of stainless steel to be selected, the main considerations are the required aesthetic standards, the corrosiveness of the local atmosphere, and the cleaning system to be adopted. However, other applications are increasingly seeking structural integrity or impermeability. .
The density of carbon steel is slightly higher than that of ferritic and martensitic stainless steel, and slightly lower than that of austenitic stainless steel;.
Due to the different uses of each product, the processing technology and the quality requirements of the raw materials are also different. Generally speaking, different stainless steel products require different thickness tolerances of raw materials. For example, .
Different product uses have different requirements for welding performance. A type of tableware generally does not require welding performance, and even includes some pot companies. However, most products require good welding performance of raw materials, such as Class II tableware, thermos cups, steel pipes, water heaters, and water dispensers..
Stainless steel is often divided into martensitic steel, ferritic steel, austenitic steel, austenitic-ferritic stainless steel and precipitation hardening stainless steel according to the state of organization. In addition, it can be divided into chromium stainless steel, chromium nickel stainless steel and chromium manganese nitrogen stainless steel according to the composition. There is also special stainless steel "GB24511_2009_Stainless steel plate and steel belt for pressure equipment" for pressure vessels..
The invention and use of stainless steel can be traced back to the First World War. British scientist Henry Brearley was commissioned by the British government's military arsenal to study the improvement of weapons. At that time, the barrel of the rifle used by soldiers was very easy to wear, and Blairley wanted to invent an alloy steel that was not easy to wear..
Stainless steel is the abbreviation of stainless and acid-resistant steel. It is called stainless steel that is resistant to weak corrosive media such as air, steam, and water, or is stainless steel; Corrosion steel is called acid-resistant steel..
Application range of pipe clamps: Light series pipe clamps are used for ordinary mechanical pressure pipes of 6 sizes series, the outer diameter of the pipe is 6-57mm. Duplex series pipe clamps are used for mechanical pressure pipes of 5 sizes series, the outer diameter of the pipe is 6-42mm. The heavy-duty series of pipe clamps are used in 8 series of high mechanical pressure pipes, with an outer diameter of 8-273mm..
As one of the common tools in life, cable ties can be seen everywhere in the market. However, more people know that cable ties are nylon cable ties that are made of plastic and have a relatively strong binding force. In fact, cable ties It is also made of stainless steel..
