Steel coil, also known as coil steel. The steel is rolled by hot pressing and cold pressing.

Steel coil, also known as coil steel. The steel is rolled by hot pressing and cold pressing. In order to facilitate storage and transportation, convenient for various processing (such as processing into steel plate, steel belt, etc.)

Profile is a solid straight strip with a certain section shape and size after plastic processing of metal.

Profile is a solid straight strip with a certain section shape and size after plastic processing of metal. There are many kinds and specifications of profiles and they are widely used and play a very important role in rolling production.

Steel pipes can be divided into two categories according to production methods

Steel pipe is not only used to transport fluids and powdery solids, exchange heat, and make machine parts and containers, it is also an economic steel. Using steel pipe to make building structure grid, pillar and mechanical support, can reduce weight, save 20 ~ 40% metal, and can realize the factory mechanized construction.

The steel type of thick steel plate is roughly the same as that of thin steel plate.

In addition, the steel plate and the material said, not all steel plates are the same, the material is not the same, the steel plate used in the place, is not the same.

Profile finishing, the outstanding point is straightening

There are two kinds of technology for profile finishing after rolling, one is the traditional hot saw cutting and straightening process, and the other is the newer long ruler cooling, long ruler straightening and cold saw cutting process.

Why does stainless steel rust?

When brown rust spots (spots) appear on the surface of stainless steel pipes, people are amazed: "Stainless steel will not rust, it is not stainless steel if it rusts, it may be a problem with the steel quality", in fact, this is a lack of understanding of stainless steel a one-sided misconception. Stainless steel can also rust under certain conditions.

What is stainless steel?

Stainless steel is a kind of steel. Steel refers to steel containing less than 2% of carbon (C), and iron when it is greater than 2%. The addition of chromium (Cr), nickel (Ni), manganese (Mn), silicon (Si), titanium (Ti), molybdenum (Mo) and other alloying elements during the smelting process improves the properties of the steel and makes the steel more resistant to corrosion. (that is, no rust), which is what we often call stainless steel.

What are the forms of corrosion of stainless steel?

Stainless steel may have excellent corrosion resistance in many media, but in others, corrosion may occur due to its low chemical stability. Therefore, stainless steel cannot be resistant to all media.

Identification method of imitation stainless steel pipe

The difference between stainless steel and stainless steel At present, the stainless steel decoration industry is full of chaos, and some fake stainless steel pipes are flooded in the decoration industry, which has a huge impact on the stainless steel decoration engineering industry.
