What is the Stainless steel tube - Stainless steel tube supplier and manufacturer

Stainless steel tube - pipe is a hollow strip of round stainless steel, which is widely used in petroleum, chemical, medical, food, light industry, mechanical instrumentation and other industrial pipelines and mechanical structural components. In addition, when the bending and torsional strength are the same, the weight is light, so it is also widely used in the manufacture of mechanical parts and engineering structures. Also used as furniture and kitchenware.

Hardness

Stainless steel pipes are generally measured by Brinell, Rockwell and Vickers hardness indexes.

Brinell hardness

Among the stainless steel pipe standards, Brinell hardness is the most widely used, and the hardness of the material is often expressed by the indentation diameter, which is both intuitive and convenient. However, it is not suitable for steel pipes of harder or thinner steel.

Rockwell hardness

The Stainless steel tube Rockwell hardness test is the same as the Brinell hardness test. The difference is that it measures the depth of the indentation. The Rockwell hardness test is a widely used method in which HRC is used in steel pipe standards only after Brinell hardness HB. Rockwell hardness can be applied to the determination of metal materials from very soft to very hard, which makes up for the Brinell method. It is simpler than the Brinell method and can directly read the hardness value from the dial of the hardness machine. However, the hardness value is not as accurate as the Brinell method because of its small indentation.

Vickers hardness

The Stainless steel tube Vickers hardness test is also an indentation test method for measuring very thin metal materials and Surface layer hardness. It has the main advantages of Brinell and Rockwell methods, and overcomes their basic shortcomings, but it is not as simple as the Rockwell method. The Vickers method is rarely used in steel pipe standards.


Development

Stainless Steels that are open at both ends and have a hollow section, and whose length is larger than the circumference of the section, can be called steel pipes. When the length is small compared to the perimeter of the section, it can be called a pipe section or a tubular fitting, which are all in the category of pipe products.


For more than sixty years, architects have used stainless steel to build cost-effective permanent buildings. Many existing buildings fully illustrate the correctness of this choice. Some are very entertaining, such as the Chrysler Building in New York City. But in many other applications, the role of stainless steel is not so compelling, but it plays an important role in the aesthetics and performance of buildings. For example, since stainless steel is more wear resistant and indentation resistant than other metal materials of the same thickness, it is the material of choice for designers when constructing sidewalks in places with large population movements.


Stainless steel has been used for more than 70 years to build new buildings and structural materials used to repair historical sites. Early designs were calculated according to basic principles. Today, design specifications, such as the American Society of Civil Engineers' standard ANSI/ASCE-8-90 "Design Specification for Cold Formed Stainless Steel Structural Parts" and the "Structural Stainless Steel Design Handbook" jointly published by NiDI and Euro Inox, have simplified service life. The design of structural components for good integrity.
