1018 stainless
Price of stainpickling or similar treatment
The product ground by the grinding belt.
2B cold rolling shall be subject to heat treatment, and then leveled to obtain appropriate gloss.
.Welding high frequency preheating plus three torch argon arc welding, high frequency preheating plus plasma argon arc welding. The progress of combined welding is very significant. As for the combined welding of steel pipe with high-frequency preheating, the weld quality is equivalent to the conventional argon arc welding and plasma welding, the welding operation is complex, and the whole welding is easy to complete automation. This combination is easy to connect with the existing high-frequency welding equipment, s is the abbreviation of steel, P is the abbreviation of plate, h is the abbreviation of hot heat, and C is the abbreviation of commercial. It generally represents hot-rolled steel plate and strip.
.Surface treatment difference: surface treatment is usually divided into polishing, wire drawing and wire drawing, and the cost is about 1 yuan and 1 meter. If it is thrown into the lens barrel,Stainless steel honing tube, the cost per ton will increase by 3000 yuan.
303— Add a small amount of sulfur and phosphorus to make it easier to cut.
Because the family kitchen and are in the same environment for a long time, the ordinary steel pipe will rust after being used for a period of time, the service life is not long, and it will affect the safety of family drinking water! Therefore, the use of stainless steel pipe here can ensure long-term non rusting, and the corrosion resistance and tensile resistance of stainless steel pipe itself. Professional stainless steel plate, stainless steel coil, stainless steel belt, stainless steel pipe, safety, environmental protection and economy! The products are exported to foreign countries and are deeply trusted, which makes the stainless steel pipe more and more popular in the field of home decoration!
2: stainless steel pipe: seamless pipe and seamless pipe (longitudinal welded pipe, decorative pipe, welded pipe, welded pipe, bright pipe). There are more than 200 kinds of standard specifications of stainless steel pipe, all sizes, and the small pipe is more expensive especially the capillary. The capillary is poor to be made of 304 material,Stainless steel heat exchanger tube, otherwise the pipe is easy to burst. You can also customize non-standard pipes for customers. Seamless pipes are mainly used in industry,Plate embossed stainless steel, and the surface is foggy, Not bright. The surface of the slotted pipe is a bright surface, commonly known as welded pipe, which is mainly used for decorative materials. In addition, the pressure resistance of industrial fluid pipe depends on the wall thickness. 310 and 310S are high temperature resistant pipes. They can be used normally below 1080 degrees, and the high temperature resistance can reach 1150 degrees
Production process of stainless steel welded pipe: raw material - strip - welded pipe - end repair - polishing - Inspection (spray printing) - Packaging - shipment (warehousing) (decorative welded pipe).
China's numbering rules adopt the use of element symbols and Chinese pinyin. Open hearth steel: P, boiling steel: killed steel: class a steel: T8: Special: ball joint steel and spring steel, such as 20CrMnTi 60simn (C content is expressed in tens of thousands)
Service first.In view of the continuous vibration of stainless steel pipe shopping malls, even & ldquo; Roller coaster & rdquo; Market, stainless steel pipe market participants are implementing it carefully & ldquo; Fast forward and fast Exit & rdquo; Therefore, the national stainless steel pipeline inventory has been at a low level. High price various specifications of stainless steel plate, stainless steel coil, stainless steel belt and stainless steel pipe. Waste merchants, industrial companies, the social inventory of stainless steel pipes should progress with the progress of economic aggregate, and with the progress of total output and demand. However, stainless steel pipe inventory did not increase too much, or even did not increase, indicating a relative decline in social inventory level. Low inventory has indeed played a role in market stability.
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.
Cold formed alloys can be cut and cold formed. However, due to its high strength and hardness, the alloy needs cold forming more than austenitic steel. Because of its high strength, springback should be fully considered.
When transporting domestic and drinking water, the pipeline shall not pass through the toxic pollution area. If necessary, protective measures shall be taken.
Work courses.Stainless steel belt, stainless steel conveyor belt, stainless steel packing belt, stainless steel belt, ultra-thin stainless steel belt.
Ferritic and martensitic stainless steels are represented by 400 series numbers. Ferritic stainless steel is marked with 430 and 446, martensitic stainless steel is marked with 4420 and 440C, dual phase (austenite ferrite).
For the length of welding arc, 2 ~ 4mm is better for ordinary steel welding, and ~ 3mm is better for stainless steel welding. If it is too long, the protection effect is not good.
. 408— Good heat resistance, weak corrosion resistance, 11% Cr, 8% Ni.
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.
After hot rolling, it is subject to heat treatment and pickling treatment.
