Price of stain
Price of 316L 302— The corrosion resistance is the same, and the strength is better because the carbon content is relatively high.
303— Add a small amount of sulfur and phosphorus to make it easier to cut.
.For more than 60 years, architects have been using stainless steel to build cost-effective buildings. Many existing buildings fully illustrate the correctness of this choice. Some are very ornamental, such as the Chrysler Building in New York City. However, the role of stainless steel is not so eye-catching, but in the aesthetics and performance of buildings For example,austenitic stainless steel pipe , because stainless steel has more wear resistance and pressure resistance than other metal materials of the same thickness, it is the preferred material for designers when building sidewalks in places with large population flow.
The application range is wider than that of ferritic stainless steel. Compared with ferritic stainless steel, duplex stainless steel has the following disadvantages: high alloy element content and relatively high price. Generally, ferritic stainless steel does not contain nickel.
.The process of this product determines its limited performance. Generally, the precision of seamless steel pipe is low: uneven wall thickness, low brightness on the inner and outer surface of the pipe, high sizing cost, and there are pockmarks and black spots on the inner and outer surface, which are not easy to remove; its detection and shaping must be processed offline. Therefore, it embodies its advantages in high pressure high strength and mechanical structure materials.
In order to prevent water from serious pollution during storage and transportation, high temperature and high pressure resistance and good sanitary performance the water industry now generally uses stainless steel pipes to store and transport water. Because stainless steel pipes have anti rust, stainless steel pipes are slowly used in the industrial field!.
5cm thick stainless steel plate shall be processed with special cutting tools, such as laser cutting machine with large wattage
400 series & mdash; Ferritic and martensitic stainless steel.
Stainless steel pipe is a kind of economical section steel and an important product in the iron and steel industry. It can be widely used in life decoration and industry. Many people on the market are used to make stair handrails, window guards, furniture, etc. 201 and 201 materials are common.
Theoretical weight of stainless steel pipe: w = outer diameter - wall thickness x wall thickness x0.02491.
Customer first.Batch size: a small number of single batch products will affect the unit price.
Classification and grading of standards 4-1 classification: national standard GB industry standard Yb local standard enterprise standard Q / cb4-2 classification: product standard packaging standard basic standard 4-3 standard level (divided into three levels): y level: international advanced level I level: international general level H level: domestic advanced level 4-4 national standard stainless steel bar (level I) gb4241-84 stainless welding disc Park (level H)
The welding performance is also much better than that of ferritic stainless steel. Generally, preheating is not required before welding and heat treatment is not required after welding.
SPCDSPCD—& mdash; Cold rolled carbon steel sheet and strip for stamping,800 stainless steel plate, equivalent to China 08Al (1323) high quality carbon structural steel.
Excellent service.Prepare materials and tools, prepare corresponding materials and tools, and check whether they match and apply.
After fine tuning the molten steel temperature in the argon blowing station, it is lifted to the ladle rotary table for continuous casting.
Windproof and ventilation. Where there is wind, please take measures to block the net, and take appropriate ventilation measures indoors.
.The inner and outer surfaces of steel pipes shall be free of cracks,Stainless steel plate 1mm thick, folds, crazing, cracks, rolling folds, delaminations and scabs. These defects shall be completely removed (except for pipes for machining). After removal, the wall thickness and outer diameter shall not exceed the negative deviation. Other minor surface defects that do not exceed the allowable negative deviation may not be removed.
Corrosion test: the industrial corrosion-resistant steel pipes provided shall be tested for corrosion resistance according to the standard provisions or the corrosion agreed by both parties, and there shall be no tendency of intergranular corrosion.
