usually also called -; %Cr,%Ni.Bidirectional Product Description: the tensile strength of the material is ~ mpa, and the high working temperature can reach ℃.Sonbothai,The corrosion resistance of corrosion-resistant stainless steel plate mainly depends on its alloy composition (chromium, nickel, aluminum silicon, manganese, etc.) And internal structure, which mainly acts on chromium. Chromium has high chemical stability, can form a passive film on the steel surface, isolate the metal from the outside, protect the steel plate from oxidation and increase the corrosion resistance of the steel plate. After the passive film, the corrosion resistance decreases.Stress relief treatment. Stress relief treatment is a heat treatment process to eliminate the residual stress of steel after cold working or welding. It is generally heated to ~ ℃ for tempering. For steels without stabilizing elements Ti and Nb, the heating temperature shall not exceed ℃, so as to avoid intergranular corrosion caused by chromium carbide precipitation. For cold worked and welded parts of ultra-low carbon and stainless steel containing Ti and Nb, they need to be heated at ~ ℃ and then cooled slowly to eliminate stress (the upper limit temperature is taken for eliminating welding stress), which can reduce the tendency of intergranular corrosion and improve the stress corrosion resistance of steel.Es Senia,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 is usually divided into stainless steel pipe, stainless steel pipe and ferritic stainless steel according to the matrix structure. Chromium content % ~ %. Its corrosion resistance, and its chloride stress corrosion resistance is better than other kinds of stainless steel.Application: utility boiler industry, mainly in key parts such as high temperature section of superheater and reheater.

The specific steps of continuous casting billet process of stainless steel pipe fittings are as follows: according to different steel grades, the vibration process of mold is matched with protective slag, which can improve the yield of %, save energy and shorten the production cycle, so as to improve the yield of molten steel.　　· Oil and gas pipeline, heat exchanger and pipe fittings.Standard classification - classification: national standard GB industry standard Yb local standard enterprise standard qcb- classification: product standard packaging standard basic standard - standard level (divided into three levels): y level: international advanced level I level: international general level H level: domestic advanced level - national standard: stainless steel bar (level I) gb- stainless welding disc Park (level H)Inspection items,Inspection: after crimping check the crimping size with a special gauge.When installing and welding the fixed port of stainless steel pipe, it is difficult to vent on the inner side, and some sides are easy to be blocked. In this case, water-soluble paper + blocking plate can be used for blocking. That is, the easy to vent and good side can be blocked with blocking plate,SonbothaiStainless steel floor heating pipe,Sonbothai2205 stainless steel belt, the difficult to vent and bad blocking plate side can be blocked with water-soluble paper, and the weld on the outer side can be blocked with adhesive tape (see Table ) .Austenitic stainless steel is generally used for manufacturing and manufacturing chemical equipment components,SonbothaiMONEL400 stainless steel plate, low-temperature equipment components in refrigeration industry, and can be used as stainless steel spring and clock spring after deformation strengthening.

Austenitic stainless steel is generally used for manufacturing and manufacturing chemical equipment components, low-temperature equipment components in refrigeration industry, and can be used as stainless steel spring and clock spring after deformation strengthening.How much does it cost?,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. after deep drawing, small black spots and RI high imitation dging will also appear on the surface of the area with large deformation, which will affect the BQ attribute.Flux coated welding wire (self shielded welding wire) shall be used for backing TIG welding.Sonbothai,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.Raw materials -- strip splitting -- welded pipe making -- heat treatment -- Correction -- straightening -- end repair -- pickling -- Hydrostatic Test -- Inspection (spray printing) - packaging -- delivery (warehousing) (pipes for welded pipe industrial piping).Crimping: during crimping, the convex part of the pipe fitting is placed in the concave groove of the die, and the jaw is perpendicular to the pipe axis.
