1. Do you know what 304 stainless steel square tube is?
304 Stainless steel pipe refers to the air, steam, water and other weak corrosion medium and acid, alkali, salt and other chemical corrosion medium corrosion of steel, also known as stainless acid steel. In practical application, the steel with weak corrosion resistance is often made of stainless steel. The corrosion resistance of stainless steel depends on the alloying elements contained in the steel grade. Stainless steel basic and gold nickel, chromium, copper, carbon, silicon, etc., has met the various uses of stainless steel structure and performance requirements.
304 stainless steel is the most widely used chromium nickel stainless steel. As a widely used steel, it has good corrosion resistance, heat resistance, low temperature strength and mechanical properties; Stamping, bending and other hot workability are good, and there is no heat treatment hardening phenomenon (service temperature -196 ℃ ~ 800 ℃). It is corrosion-resistant in the atmosphere. If it is an industrial atmosphere or heavily polluted area, it needs to be cleaned in time to avoid corrosion. Suitable for food processing, storage and transportation. It has good machinability and weldability. Plate heat exchangers, bellows, household products (Class 1 and 2 tableware, cabinets, indoor pipelines, water heaters, boilers, bathtubs), auto parts (windshield wipers, silencers, molded products), medical appliances, building materials, chemicals, food industry, agriculture, ship parts, etc. 304 stainless steel is a nationally recognized food grade stainless steel.
2. Characteristics of 304 stainless steel pipe
(1). 304 stainless steel pipe is very environmentally friendly, safe and reliable.
(2). 304 stainless steel pipe can bend with high Gini performance to a great extent. We know that the construction environment often affects the stainless steel pipe, but the staff will carry out the construction according to the super distortion of the stainless steel pipe.
(3). 304 stainless steel pipe has extremely excellent acid-base corrosion resistance. There is a very thin protective film on the outer surface of the stainless steel pipe, but it is very hard. Even if the stainless steel pipe is damaged, as long as there is oxygen around, it will regenerate quickly and there will be no rust.
(4). 304 stainless steel pipe is very light in weight, which makes it convenient to carry and install it, and greatly reduces the cost of the project.
3. How about 304 stainless steel pipes?
·304 stainless steel pipe is a brand of stainless steel produced in accordance with ASTM standards in the United States. 304 stainless steel pipe is equivalent to China's 0Cr19Ni9 (0Cr18Ni9) stainless steel pipe.
·304 stainless steel pipe is a universal stainless steel pipe, it is widely used in the production of good comprehensive performance (corrosion resistance and formability) equipment and parts. Such as food equipment, general chemical equipment and nuclear industry equipment.
·304 stainless steel is a universal stainless steel material, rust resistance is better than 200 series of stainless steel material. High temperature resistance is also better, can be high to 1000-1200 degrees. 304 stainless steel has excellent corrosion resistance and good corrosion resistance.
4. Do you know much about stainless steel square tubes?
· Stainless steel square tube is a hollow strip of steel, because the cross section is square so called square tube. A large number of pipelines used for conveying fluid, such as oil, natural gas, water, gas, steam, etc., in addition, in bending, torsion strength at the same time, lighter weight, so also widely used in manufacturing machinery parts and engineering structures.
·Stainless steel square tube classification: square tube is divided into seamless steel tube and welded steel tube (seam pipe) two categories. According to section shape can be divided into square and rectangular tube, widely used is circular steel tube. But there are some semicircular, hexagonal, equilateral triangle, octagonal and other special-shaped steel tube.
5. What are the specifications and sizes of 304 stainless steel pipes?
Length of stainless steel pipe (6m), thickness of stainless steel pipe, diameter of stainless steel pipe.
304 stainless steel round pipe sizes (8, 9.53, 10, 11.11, 12, 12.7, 14, 15.9, 18, 19.1, 20.5, 22.22,

304 stainless steel rectangular tube sizes
The thickness sizes of 304 stainless steel pipe is: 0.8mm, 1mm, 1.2mm, 1.5mm, 2.0mm, 2.5mm, 3.0mm, 4.0mm. Note: this kind of 304 stainless steel pipe is not an industrial square pipe, but an ordinary round pipe and austenitic stainless steel water pipe for water supply. Therefore, the thickness of the pipe is not as much as that of the square pipe, which can be extended to 100mm.
6. What are the sizes of stainless steel square tubes?
Specifications of stainless steel tube generally only look at its inner diameter and wall thickness, its length can be determined according to the needs of consumers, the common specifications of stainless steel tube on the market as follows:
