Martensitic stainless steels typical martensitic stainless steels include Cr ~ Cr and Cr, which have good processing properties. Deep drawing, bending, crimping and welding can be carried out without preheating. Crl does not require preheating before cold deformation, but preheating is required before welding. crlcr is mainly used to make corrosion-resistant structural parts such as steam turbine blades, while crcr is mainly used to make surgical and wear-resistant parts of medical instruments; crl can be used as corrosion-resistant bearings and tools.Stainless steel pipes can be divided into CR series ( Series), Cr Ni series ( Series), Cr Mn Ni series ( Series) and precipitation hardening series ( Series). Series & mdash; Cr Ni Mn austenitic stainless steel series & mdash; Cr Ni austenitic stainless steel.Calle-Blancos,: stainless steel plate: it can be divided into cold-rolled plate and hot-rolled plate. Its surface has bright surface, fog surface and matte surface. It is commonly known as stainless steel plate, including B plate and Ba plate. In addition, it can also be plated with other light colors according to customer requirements. The main specifications of plates are: m * m, m * m, m * m, m * M, m * m. If customer demand is large, we can cut them according to customer size. In addition, we can replace wire drawing plate, anti sliding plate and electroplating plateApplication: utility boiler industry, mainly in key parts such as high temperature section of superheater and reheater.Inderbor,Indicates that the chemical composition is represented by international chemical element symbols and national symbols, and the composition content is represented by letters: for example, China and Russia use fixed digit numbers to represent steel series or numbers; For example,Calle-BlancosStainless steel welded pipe factory, the United States, Japan, series, series and series; The serial number is composed of Latin letters and order which only indicates the purpose.Production mode stainless steel pipe can be divided into seamless pipe and welded pipe according to the production mode. Seamless steel pipe can be divided into hot-rolled pipe, cold-rolled pipe, cold drawn pipe and pipe. Cold drawing and cold rolling are the secondary processing of steel pipe; Welded pipe is divided into straight seam welded pipe and spiral welded pipe.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, and a small number of pipes with acid pickling industrial surface. As mentioned above, stainless steel product pipe belongs to the purpose of stainless steel products, because the outer diameter size, acid, 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.

When the stainless steel pipe with solid core welding wire is prefabricated, the welded junction can usually be rotated for welding, and the ventilation is very easy. At this time, the blocking plate is usually used to block both sides of the welded junction in the pipe, and the bottom welding is carried out for the protection of ventilation (see Table ), and the outside is blocked with adhesive cloth.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,Calle-BlancosStainless steel bridge filter pipe, and there shall be no tendency of intergranular corrosion.Ferritic stainless steel the Cr content of ferritic stainless steel is generally % ~ % and the carbon content is less than .%. Other alloying elements are sometimes added. The metallographic structure is mainly ferrite, and there is no & alpha during heating and cooling=& amp; amp; gt;& gamma; The transformation cannot be strengthened by heat treatment. Strong oxidation resistance. At the same time, it also has good hot workability and certain cold workability. Ferritic stainless steel is mainly used to make components with high corrosion resistance and low strength requirements. It is widely used in manufacturing equipment such as production, nitrogen fertilizer and chemical pipelines.Respect for customers,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 heat treatment austenitic stainless steel commonly used heat treatment processes are: solution treatment,Calle-BlancosStainless steel cooling pipe, stabilization treatment and stress relief treatment.Stainless steel seamless steel pipe for fluid transportation (instead of gbt- instead of gbt- instead of gb-)

Austenitic stainless steel has good resistance to uniform corrosion, but there are still the following problems in local corrosion resistance: intergranular corrosion of austenitic stainless steel. Austenitic stainless steel will have intergranular corrosion when it is kept warm at ~ ℃ or cooled slowly. The higher the carbon content the greater the tendency of intergranular corrosion. In addition, intergranular corrosion also occurs in the heat affected zone of the weldment. This is due to the precipitation of Cr rich CrC on the grain boundary. The chromium poor area is formed in the surrounding matrix, which is caused by corrosion of the primary cell. This intergranular corrosion phenomenon also exists in the ferritic stainless steel mentioned above.Total quality management,There are mechanical, chemical and electrochemical methods to remove the scale of stainless steel pipe. Due to the complexity of the composition of the scale of stainless steel pipe, it is not easy to remove the scale on the surface and make the surface highly clear and flat. Generally, the removal of the scale of stainless steel pipe should be carried out in two steps, the first step is pretreatment and the second step is ash removal.Usage: widely used in automobile, tractor and other industries.After molten steel casting, stainless steel pipe fittings generally adopt the same vertical, vertical bending or arc continuous caster as carbon steel. The refined molten steel is poured into the ladle, the ladle to be poured is transferred above the tundish mouth through the rotary table, and then the molten steel is tundish through the long nozzle. The molten steel in tundish enters the mold through the submerged nozzle for forming,When using this method, it should be noted that the water-soluble paper should be double-layer and must be pasted well, otherwise it is easy to cause damage and fall off of the water-soluble paper, resulting in loss of argon protection of the inner weld and oxidation, resulting in cutting of the weld junction and re welding, the water-soluble paper should be strictly checked and pasted before welding.The continuous casting of stainless steel pipe fittings is generally matched with the refining furnace, which has strict requirements on the chemical composition and temperature of molten steel; In order to prevent secondary oxidation of molten steel, non oxidation protection pouring is required during continuous casting production; Strict requirements for refractory materials such as ladle, tundish, nozzle and submerged nozzle.Flux coated welding wire (self shielded welding wire) shall be used for backing TIG welding.
