Stainless Steel Special-shaped Tubes

• ​Introduction

Stainless steel special-shaped tubes have a variety of shapes, such as elliptical, flat, triangular, hexagonal, etc. Compared with ordinary circular stainless steel pipes, they can meet the special requirements of different engineering designs for the shape and size of pipes, and have unique advantages. They are widely used in construction, automotive, aerospace, chemical and other industries.

• ​Main Functions

Good load-bearing capacity: Stainless steel special-shaped tubes usually have a larger moment of inertia and section modulus, so they have strong bending and torsion resistance, which can significantly reduce the structural weight and save steel.

Corrosion resistance: The stainless steel material itself has excellent corrosion resistance, and can maintain its strength and appearance integrity for a long time even in harsh environments, so it is widely used in industries with high corrosion resistance requirements such as chemical engineering and food processing.

Meet special shape requirements: It can be customized into various special shapes according to customer needs, which is suitable for some occasions with special architectural or mechanical design requirements, such as building facades, decorative pipes, and various precision parts.

Aesthetic function: The surface of the stainless steel special-shaped tube is smooth, and its unique shape and luster can enhance the aesthetic effect, so it is also widely used in decorative fields.

Good mechanical properties: It has high strength and pressure resistance, and can be used as an important support structure in the fields of construction and mechanical manufacturing.

• ​Tubing Standards

ASTM A554, ASTM A269 ; EN 10217-7； GB/T 12771，GB/T 3094.

• Material & Performance

304/304L，316/316L，430 etc. 1.4301/1.4306,1.4401/1.4404, 1.4016 etc.

The commonly used materials are 304, 304L, 316,430 stainless steel, etc. 304 stainless – steel has good comprehensive performance, with excellent corrosion resistance and formability, and can resist the corrosion of most organic acids and inorganic acids. 316 stainless – steel has better corrosion resistance than 304, especially in chloride – containing environments, and is often used in occasions with higher corrosion – resistance requirements. These stainless – steel materials have high strength, good toughness, and can maintain stable performance in a certain temperature range.430 stainless steel is a type of ferritic stainless steel. It has good corrosion resistance and oxidation resistance, and its price is relatively low. It is often used in architectural decoration parts that do not require high strength, such as decorative panels.Commonly used stainless steel has good ductility, which is convenient for cold working, bending, welding and other processing operations, and can be processed into various special – shaped structures.
