hydraulic test shall be carried out to test their pressure resistance and quality. If there is no leakage under the specified pressure
SPHDSPHD—& mdash; Hot rolled steel plate and strip for stamping.
For the steel pipes bearing fluid pressure, flaring test and flattening test according to the standard or the requirements of the demander.
.Low temperature processing of stainless steel pipe --- martensite series stainless steel is quenched from austenitizing temperature and then cooled to very low temperature to promote martensite quenching. It is suitable for stainless steel easy to produce residual austenite.
SPCC stainless steel belt is simply an extension of ultra-thin stainless steel plate. It is mainly a narrow and long steel plate produced to meet the needs of industrialized production of various metal or mechanical products in different industrial sectors.
.Stainless steel coil is widely used in chemical industry,316L stainless steel plate inlet, food, medicine, papermaking petroleum, atomic energy and other industries, as well as various parts of buildings, kitchenware, tableware, vehicles and household appliances. 304 stainless steel coil is divided into austenitic stainless steel cold rolled coil and stainless steel hot rolled coil. 304 stainless steel (coil) plate features: beautiful surface and diversified use possibilities; Good corrosion resistance; Longer and more durable than ordinary steel; Good corrosion resistance; High temperature oxidation resistance and high strength, so it can resist fire; Good plasticity and welding performance. It has excellent rust and corrosion resistance, good intergranular corrosion resistance and good processing performance.
1 cold rolled oriented silicon steel strip (sheet) represents: 100 times of DQ + iron loss value (at the frequency of 50Hz, the magnetic induction peak with sinusoidal waveform is the unit weight iron loss value of 7T) + 100 times of thickness value. Sometimes G is added after the iron loss value to indicate high magnetic induction. For example, dq133 represents cold-rolled oriented silicon steel strip (sheet) with iron loss value of 3 and thickness of 0.3mm. Now the new model is 30q133.
In conclusion, when calculating the approximate weight of stainless steel pipe and multiplying it by the unit price, the price of 6m stainless steel pipe can be roughly obtained, which can be used in the project budget.
When selecting stainless steel water supply pipe, carefully observe whether the surface of the pipe is shiny, damaged and crushed, and pay attention to whether the incision is neat. If these phenomena occur, they should be carefully considered.
Model & mdash; General model; 188 stainless steel. The GB brand is 0Cr18Ni9.
The heat-treated alloy should be 1900 DEG at low temperature; Annealing treatment at the temperature of F,Stainless steel seamless square tube, then rapid cooling and water quenching. This treatment is applied to solid melt annealing and stress relief. Stress relief treatment, such as below 1900 DEG; F, which is easy to lead to the precipitation of harmful metal or non-metallic phases.
Where to sell API.Logistics cost: different delivery locations determine different transportation costs. The long-distance transportation cost should be 500 yuan per ton and the short-distance transportation cost should be about 300 yuan per ton.
Characteristics and application 347h austenitic stainless heat strength steel has good corrosion resistance, welding performance and heat strength performance. 347h stainless steel is used for large boiler superheater, reheater, steam pipeline and petrochemical heat exchanger pipe fittings.
Cold rolled steel strip for deep drawing is a low-carbon high-quality carbon structural steel cold-rolled steel strip for deep drawing complex drawing parts.
Theoretical weight: Cr Ni austenitic stainless steel austenitic stainless steel (kg / M) s-wall thickness (mm)
technological innovation.Stainless steel belt stainless steel conveyor belt,Stainless steel 20 thick plate, stainless steel packing belt, stainless steel coil belt, ultra-thin stainless steel belt.
AUSTENITIC FERRITIC duplex stainless steel. It has the advantages of both austenitic and ferritic stainless steel, and has superplasticity. Martensitic stainless steel. High strength, but poor plasticity and weldability.
Stainless steel pipe national standard thickness in the stainless steel pipe industry, the steel that meets the national standard is generally called & ldquo; National Standard & rdquo; Inferior steel that does not meet national standards is called & ldquo; Winning the bid& ldquo; Non standard & rdquo; In practical application, the quality of national standard and non-standard is similar, mainly due to the difference in thickness. A thickness of national standard is actually 1mm, but a thickness of non-standard is actually only 0.8mm or other thickness less than 1mm. Non-standard is basically equivalent to winning the bid. Standard index size (323mm) label number standard implementation standard gbt14976-2012 non-standard specific thickness ratio outer diameter steel pipes are produced according to the standard. 2 non-standard belongs to customized difference. Wood office says ha ha customized on demand. 3 thickness area: the difference between standard, thickened, stainless steel American Standard and national standard mainly lies in C content and P content; The C content and P content of Chinese standards are lower than those of American Standard ASTM A312@_@ The two important elements of material are chromium and nickel, not in the national standard. The corresponding national standard is 06cr19ni10.
.There are ba face, 2b face, (white skin), 2D face, (frosted), HL (wire drawing), 8K face and other surfaces with good quality and brightness.
5cm thick stainless steel plate shall be processed with special cutting tools, such as laser cutting machine with large wattage
The product ground by the grinding belt.
