Dragor430 stainless steel stripWhat industry can be used

DragorStainless steel honing tube,

Stainless steel pipe is durable and has been recognized by the engineering community,DragorStainless steel necked pipe, and relevant parties are starting from reducing the wall thickness and lowering the grid, so as to facilitate further development. In particular, the price of stainless steel pipe is not high, so the supporting connection, Guangdong, Zhejiang, Jiangsu and other places, which is a promising pipe. The Ministry of construction and relevant departments also attach great importance to this new type of pipe. According to China technology market management promotion center and gksz [] No. document on Application & ldquo; High diameter to wall ratio and high precision stainless steel medium and high pressure water supply pipes and supporting fittings and special technology & rdquo; It is learned from the notice that the application of stainless steel pipe technology and product is of great significance to improve the grade of modern buildings in China and improve and ensure the water quality of water supply.The corrosion resistance of stainless steel depends on chromium, but because chromium is an integral part of steel, the protection is different.Dragor,　　SPHCSPHC—& mdash; In the first place, 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.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.Milzabur,Deburring: after the pipe is cut off, the burr shall be removed to avoid cutting the sealing ring.Household worries.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, save energy and shorten the production cycle, so as to improve the yield of molten steel.

Production process of stainless steel pipe A. preparation of round steel; b. Heating; c. Hot rolling perforation; d. Cutting head; e. Pickling; f. Grinding; g．； h. Cold rolling; i. Degreasing; j. Solution heat treatment; k. Straightening; l. Pipe cutting; m. Pickling; n. Finished product inspection.　　Add a small amount of sulfur and phosphorus to make it easier to cut.resources,Model & mdash; Except that the risk of weld corrosion of the material is reduced due to the addition of titanium, other properties are similar. Stainless steel decorative pipe, stainless steel pipe, series stainless steel pipe & mdash; Ferritic and martensitic stainless steel model & mdash; Good heat resistance, weak corrosion resistance, % Cr, % Ni.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.Austenitic stainless steel. It contains more than % chromium, titanium, nitrogen and other elements. Good comprehensive performance and resistance to corrosion of various media.

The back is blocked with blocking plate for ventilation protection; Only soluble paper or the combination of soluble paper and blocking plate is used for blocking ventilation protection; Use flux cored wire for backing TIG welding.property right,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, toughness and weldability increase with the increase of chromium content, and its chloride stress corrosion resistance is better than other kinds of stainless steel.B cold rolling shall be subject to heat treatment, pickling or similar treatment, and then leveled to obtain appropriate gloss. the responsibility of the calender is that the annealed steel strip is blackened, the furnace liner is perforated,DragorS30815 stainless steel plate, and ammonia leakage will cause rust. . The responsibility of the steel plant is that the peeling and trachoma of the steel strip will cause rust. Substandard materials will cause rust. the responsibility of the calender is that the annealed steel strip is blackened, the furnace liner is perforated, and ammonia leakage will cause rust. . The responsibility of the pipe manufacturer: the welds in the pipe manufacturer are polished rough, which will cause rust.Dragor,Bidirectional Product Description: the tensile strength of the material is ~ mpa and the high working temperature can reach ℃.This material without titanium and niobium has an inherent tendency of intergranular corrosion. Intergranular corrosion can be reduced by adding titanium and niobium and stabilizing treatment. It is a kind of high alloy steel that can corrode in air or chemical corrosive medium. Stainless steel has beautiful surface and good corrosion resistance. It does not have to undergo surface treatment such as color plating to play a role of rust freeMarking: in order to make the steel pipe complete the socket of the pipe fitting, the length must be marked and marked at the pipe end.
