BocoyStainless Steel Coil MillDemand recovers and prices still have room for improvement

The petrochemical industry, including the chemical fertilizer industry, has a great demand for stainless steel pipes. Stainless steel seamless pipes are mainly used in this industry. The specifications include 3032331634317l, etc. the outer diameter is about ￠ 18- ￠ 610, and the wall thickness is about 6mm-50mm (generally, the selected specifications are

0cr21ni5ti, 1Cr21Ni5Ti, etc. Duplex stainless steel has good weldability, no heat treatment is required after welding, due to the high Cr content, it is easy to form σ Pay attention when using.

Bocoy.If you want to choose a high-quality thin-walled 304 stainless steel pipe water supply pipe, you should first see whether its material is superior. Stainless steel is a material with strong corrosion resistance and high sanitation and cleanliness. The outer wall is not only very beautiful, but also very clean. The cut is good. Is the thin-walled 304 stainless steel pipe water supply pipe superior

Stabilization treatment. Generally, it is used for 18-8 steel containing Ti and Nb in the solid solution treatment line. After the solid solution treatment, the steel is heated to 850~880 ℃ for heat preservation and air cooling. At this time, the carbides of Cr are completely dissolved, while the carbides of titanium are not completely dissolved, and they are fully analyzed during the cooling process

.Stainless steel plate cutting stainless steel plate with three-dimensional five axis laser greatly improves the cutting efficiency of stainless steel plate, and nitrogen protection is provided during cutting. Thorns. The cut shall be smooth. Stainless steel plate mesh laser drilling high energy laser beam breaks down on stainless steel plate to form a

Dry it in the air below, not giving the germs a place to live.

In the building water supply piping system, due to the end of the glorious history of galvanized steel pipe, various new plastic pipes and composite pipes have developed rapidly, but various pipes still have some shortcomings in varying degrees, a protective film will be attached to the surface of stainless steel plate to ensure the gloss of the surface and prevent scratching. It can also effectively prevent scratches during transportation. The outer protective film is also a very important point. If the protective film with poor quality is placed for a long time, the

D for rolling and B for bright finishing rolling.

It is divided into two steps, one is pretreatment, and the second step is ash removal.

Workshop cost.As we know there are different types of stainless steel plates. Different types of stainless steel plates are used in different scenarios. It mainly depends on the carbon, manganese, nickel, chromium and other aspects to distinguish whether the stainless steel plate is 201 or 304.

Stainless steel pipes are divided into hot rolled, hot drawn and cold drawn (rolled) stainless steel pipes according to the connection and rolling process. According to the difference of metallographic structure of stainless steel, it mainly includes semi Ferritic and semi martensitic stainless steel pipe, martensitic stainless steel pipe,Bocoy904L stainless steel pipe manufacturer, austenitic stainless steel pipe and AUSTENITIC FERRITIC system

It is a low-carbon high-alloy stainless steel. Because the nickel content in its composition is less than 4% the steel contains ferrite austenite structure, so it is called duplex stainless steel. Generally speaking, duplex stainless steel has a good balance of alloy elements, including ferrite elements such as chromium and molybdenum, as well as austenite

: 8K mirror, 2b smooth surface, sanding, titanium,Bocoy304 stainless steel pipe price 1m, Ba plate, etc.

Quality inspection report.In austenite and then rapidly cooled. Air cooling can be adopted for thin-walled parts, and water cooling is generally adopted.

After completion, it also has a certain bending sequence. The principle is to fold the next one first if there is no interference and then fold the next one if there is interference.

2. Raw materials of stainless steel pipes. If the hardness is too low, it is not easy to polish (BQ is not good). If the hardness is too low, orange peel is easy to appear on the surface during deep drawing, affecting BQ performance. BQ with high hardness is relatively good.

Bocoy.Steel pipes are made of steel billets of acid and heat resistant grades through heating, perforation, sizing,Bocoy316L stainless steel pipe factory, the thickness of conventional brushed stainless steel is generally less than 12mm. If it is used as decorative plate, such as equipment shell, decoration engineering, outer wall of non pressure vessel, etc., the thickness of stainless steel plate is generally between 0.8mm-6mm; Large equipment, pressure vessels, pressure bearing structures, etc

When using this method, resulting in the loss of argon protection of the inner weld and oxidation otherwise the water-soluble paper may be damaged and fall off, resulting in the cutting of the weld crater and re welding, which can not guarantee the welding quality, but also seriously affect the welding quality
