What causes the hardness of stainless steel pipes to be affected?

What causes the hardness of stainless steel pipes to be affected?

In fact, this is a relatively professional problem. Now, stainless steel pipes made of 304 and 201 materials are basically used. There are two factors that affect the hardness of stainless steel pipes: annealing of steel strips and carbon content of stainless steel pipes. One factor is the problem of annealing the steel strip of the stainless steel tube. The quality of the annealing treatment of the steel strip is directly related to the hardness of the stainless steel tube. Whether it is 201 or 304 stainless steel tube, the country has corresponding standards for its hardness. Another factor is the carbon content in the stainless steel pipe. The main function of carbon in the stainless steel pipe is to increase the hardness of the pipe, but carbon is also an impurity in the stainless steel. will be bigger. Xiyouwo stainless steel has high copper content. The pipes of the same specification and thickness are softer and easier to process and shape, so they are your best choice.

Is the stainless steel tube as hard as possible?

Is the stainless steel tube as hard as possible?

People are often asked, "Is the harder the stainless steel pipe, the better?" Many users think that the harder the stainless steel pipe, the better the quality of the stainless steel pipe, especially for stainless steel anti-theft windows and railings, the higher the hardness of the pipe. The more sturdy, but is the actual situation like this?

Why does stainless steel also rust?

Why does stainless steel also rust?

When brown rust spots appear on the surface of stainless steel pipes, people are amazed: "Stainless steel does not rust, and rusted is not stainless steel. Is there a problem with the steel?". This is a one-sided misconception about the lack of understanding of stainless steel. Stainless steel can also rust under certain conditions.

Simple classification of stainless steel pipes

Simple classification of stainless steel pipes

Generally, there are stainless steel round tube wall thickness: 0.4 ~ 12mm, outer diameter: 6mm ~ 600mm, of which φ16mm ~ 76mm can produce two flower to full flower flower tube; Foshan stainless steel square tube wall thickness: 0.4 ~ 4.0mm, outer diameter: 12 × 12 ～163×163mm; Foshan stainless steel rectangular tube wall thickness: 0.4～4.0mm, outer diameter: 20×10～120×60mm; Foshan stainless steel fan-shaped tube wall thickness: 0.7～1.0mm, outer diameter: R16～R19; Foshan stainless steel oval Tube: 80×40～92×58; it is also the main stainless steel welded pipe for fluid transportation.

Stainless steel decorative pipes are all the same length?

Stainless steel decorative pipes are all the same length?

1. Regular length of stainless steel pipe. Basically, the pipes of stainless steel pipe manufacturers are of the same length, most of which are 6 meters long. This length also takes into account the transportation problem. 2. The length of the stainless steel color tube. Before, because the length of the ordinary stainless steel tube was 6 meters, I also wanted to make the color stainless steel tube into 6 meters, but the molds of the titanium plating factory for vacuum electroplating were mostly less than 6 meters, maybe 3 or 4 meters, so it was made into 6 meters. Rice has to change the mold to increase the cost, and naturally the price will be higher. The cost of titanium plating itself is higher than the price of the pipe itself. In order to achieve a price acceptable to customers, everyone is willing to use colored stainless steel pipes, so The length of the standing colored stainless steel pipe is basically 4 meters.

Description of professional terms for stainless steel

Description of professional terms for stainless steel

There are many ways to classify stainless steel. According to the structure at room temperature, there are martensitic, austenitic, ferritic and duplex stainless steels; according to the main chemical components, they can be basically divided into two major systems: chromium stainless steel and chromium-nickel stainless steel; There are nitric acid-resistant stainless steel, sulfuric acid-resistant stainless steel, seawater-resistant stainless steel, etc., which can be divided into pitting corrosion-resistant stainless steel, stress corrosion-resistant stainless steel, intergranular corrosion-resistant stainless steel, etc. according to the type of corrosion resistance; Magnetic stainless steel, free cutting stainless steel, low temperature stainless steel, high strength stainless steel, etc. Due to its excellent corrosion resistance, formability, compatibility and toughness in a wide temperature range, stainless steel has been widely used in heavy industry, light industry, daily necessities industry and building decoration industries. .
