Series & mdash; martensitic precipitation hardening stainless steel pipe.The numbering rules adopt element symbols; Pinyin, open hearth steel: p; Boiling steel: F; Killed steel: B; Class a steel: a; T: special GCr: ball.Saveh, b face, (white skin), D face, (frosted), HL (wire drawing),Saveh2205 stainless steel strip, K face and other surfaces with good quality and brightness.Argon shall conform to the rules of national specifications, and argon with purity of % shall be selected. If the content of impurities is too high, the maintenance effect of argon will be weakened and the weld quality will be indirectly affected.Veternik,Model & mdash; High strength cutting tool steel, with slightly higher carbon content can obtain higher yield strength after appropriate heat treatment, and the hardness can reach hrc. It belongs to hard stainless steel. A common application example is & ldquo; Shaving blade & rdquo;. There are three common models: C and f (easy to process).All steel with openings at both ends and hollow sections, and with a large ratio of length to section perimeter, can be called steel pipe. When the ratio of length to section perimeter is small, it can be called pipe section or tubular fittings, which belong to the category of pipe products.After that, the second widely used steel is mainly used in food industry, pharmaceutical industry and surgical equipment. Adding molybdenum makes it obtain a special corrosion-resistant structure. Because it has better chloride corrosion resistance than stainless steel pipe, it is also used as & ldquo; marine steel & rdquo;. SS is usually used in nuclear fuel recovery devices. Grade stainless steel Steel pipes usually also meet this application level.

Stainless steel pipes and water transmission equipment for fluid transportation such as water and gas are advanced basic water purification materials in the world. They have strong anti-corrosion performance,SavehStainless steel pipe Market, which can not be compared with cast iron pipes, carbon steel pipes and plastic pipes.The folded stainless steel hot rolled strip is hot rolled into a strip with a thickness of mm-mm and a width of mm-mm.Therefore, there are requirements for the service environment of stainless steel, and it is necessary to remove dust frequently and keep it clean and dry.original,Clamping connection steps: cut off the pipe according to the required length. When breaking the pipe, it shall not be too large to prevent the pipe from being out of round.Decorative stainless steel pipe: usually the outer wall is relatively bright, so its name is considered. Decorative stainless steel pipe is used for decorative purposes. The stainless steel pipe for general decorative purposes is relatively thin. Because it is different from the manufacturing process of stainless steel product pipe, the price also varies greatly. The general production process of decorative stainless steel pipe is ordinary welded stainless steel pipe. Guangdong stainless steel product pipe stainless steel product pipe: generally, the surface of stainless steel product pipe is also a bright surface, stainless steel product pipe belongs to the purpose of stainless steel products, because the outer diameter size, mechanical properties, acid, alkali and corrosion resistance of stainless steel pipe are relatively good, Therefore, stainless steel pipes are generally used as anti-corrosion materials or hardware products in large-scale production enterprises. The production process of stainless steel pipes is one-time forming, and nitrogen protection is also added during welding.The selection of pipes and fittings for welding data preparation shall be based on the quality elements of the application environment, chemical composition and application pressure, and the commodities of corresponding grades shall be selected to ensure the weld metal structure and machine function.

Adjust the ratio of austenite forming elements to ferrite forming elements in the steel to make it have austenite + ferrite dual phase structure,SavehStainless steel cooling pipe, in which ferrite accounts for % - %. This dual phase structure is not easy to produce intergranular corrosion.Test conclusionModel & mdash; Martensite (high strength chromium steel), good wear resistance and poor corrosion resistance.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.Typical ferritic stainless steels are Crl, Cr and Cr.Saveh,Inspection: after crimping, check the crimping size with a special gauge.Ferritic and martensitic stainless steels are represented by series numbers. Ferritic stainless steel is marked with and martensitic stainless steel is marked with and C, dual phase (austenite ferrite).Austenitic stainless steel. It contains more than % chromium, about % nickel and a small amount of molybdenum, titanium
