Steel strip, thin strip, roll strip, calendering strip and other strips can be cut with a thickness of 0.03 to 0mm (Note: stainless steel calendering strips of various thickness and width can be produced according to the needs of customers)

There are ba face, 2b face, (white skin), 2D face, (frosted), HL (wire drawing), 8K face and other surfaces with good quality and brightness.

.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.

Stainless steel water supply pipe is a healthy, economic, sanitary and energy-saving water pipe, whether it is for household or large engineering buildings

.6 Density 400 & rdquo; Density of series: 93310s, 309S and 316316 density stainless steel coils of 30323042001 are divided into Austenitic, ferrite, martensite, duplex (ferrite austenite) stainless steel cold rolled coil and stainless steel hot rolled coil.

There are ba face, 2b face, (white skin) 2D face, (frosted), 8K face and other surfaces with good quality and brightness.

Stainless steel pipe is a common material in stainless steel, with a density of 93 GCM, which is also called 188 stainless steel in the industry. High temperature resistance of 800 ℃, with the characteristics of good processing performance and high toughness, it is widely used in industry, furniture decoration industry and food and medical industry.

Low temperature processing --- martensitic stainless steel is quenched from austenitizing temperature and then cooled to very low temperature to promote the quenching of martensite. It is suitable for stainless steel which is easy to produce retained austenite.

When the addition of chromium reaches 5%, the atmospheric corrosion resistance of steel increases significantly, but when the chromium content is higher, although the corrosion resistance can still be improved it is not obvious. The reason is that when alloying steel with chromium, the type of surface oxide is changed to be similar to that formed on pure chromium metal. This tightly adhered chromium rich oxide protects the surface from further oxidation. This oxide layer is very thin. Through it, you can see the natural luster of the steel surface, which makes the stainless steel have a unique surface. Moreover, if the surface layer is damaged, the steel surface will react with the atmosphere to repair itself re form this passive film and continue its protective effect.

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, 15 9 large plants and 18 8 large plants of national standard and 18 8 small plants of American Standard 132@_ @ The national standard contains more than 17 chromium and the American Standard contains more than 18 chromium@_@ Stainless steel pipe is an American Standard, not in the national standard. The corresponding national standard is 06cr19ni10.

Recommendation and consultation.According to the purpose, it is mainly divided into oil well pipe (casing, oil pipe and drill pipe), pipeline pipe, boiler pipe, mechanical structure pipe hydraulic prop pipe, gas cylinder pipe, geological pipe, chemical pipe (high-pressure fertilizer pipe, petroleum cracking pipe) and marine pipe. Calculation formula for weight of stainless steel square tube: (nozzle perimeter 14 - actual thickness) actual thickness is 0.02491, such as automotive accessories. Good formability, but poor temperature resistance and corrosion resistance.

  SPCCSPCC—& mdash; Cold rolled carbon steel sheet and strip are generally used, which is equivalent to q195a. The third letter C is the abbreviation of cold. When it is necessary to ensure the tensile test, add t at the end of the brand as spcct.

2B cold rolling shall be subject to heat treatment, pickling or similar treatment, and then leveled to obtain appropriate gloss.

Interpretation and observation.. The agitation in the futures market is more direct. If there is an abnormal change in inventory, whether it increases or decreases, it will become a speculative type of mall participants.

The welding of stainless steel pipe is usually composed of backing welding, filling welding and cover welding. Backing welding of stainless steel pipe is a key link in stainless steel pipe welding, which is not only related to the quality of engineering

Because the family kitchen and are in the same environment for a long time, the ordinary steel pipe will rust after being used for a period of time, the service life is not long, and it will affect the safety of family drinking water! Therefore, the use of stainless steel pipe here can ensure long-term non rusting, and the corrosion resistance and tensile resistance of stainless steel pipe itself. Professional stainless steel plate, stainless steel coil, stainless steel belt, stainless steel pipe, safety, environmental protection and economy! The products are exported to foreign countries and are deeply trusted, which makes the stainless steel pipe more and more popular in the field of home decoration!

.As long as it is a socket connected stainless steel wire, it is slightly thinner than that of raw materials. At present, the stainless steel pipe industry is dominated by large negative difference, mainly for the consideration of cost saving, 0 thickness. It provides all kinds of stainless steel plates, stainless steel coils, stainless steel belts, stainless steel pipes for individuals and enterprises all over the country for a long time, there will be 0.91 ~ 1.

In the building water supply pipe system, since the galvanized steel pipe has ended its glorious history of one hundred years, various new plastic pipes and composite pipes have developed rapidly. The professional stainless steel plate, stainless steel coil, stainless steel belt and stainless steel pipe have advanced technology, strict testing, there are still some deficiencies in various pipes to varying degrees, relevant experts: building water supply pipes will eventually return to the era of metal pipes. According to foreign application experience, stainless steel pipe is recognized as one of the pipes with good comprehensive performance in metal pipe. Chemical analysis: carry out chemical analysis on the chemical composition of the material, and the chemical composition meets the requirements
