Stainless stee
Stainless steeThe stainless steel pipe installed on the pipeline support can be corroded by 200 ppm chloride ion and 2 ppm residual chlorine in an aerobic environment. For carbon steel structural supports, the pipeline shall be insulated to prevent corrosion due to potential difference, and the external insulation cotton shall be wrapped for anti-corrosion treatment. Remember, never use glue and other materials that contain chloride ions, halogens and other corrosive effects on stainless steel pipes.
Japanese cold rolled non oriented silicon steel strip consists of nominal thickness (expanded by 100 times) + code a + iron loss guarantee value (the value after expanding the iron loss value when the frequency is 50Hz and the large magnetic flux density is 5T by 100 times). Provide various brand products such as stainless steel plate, stainless steel coil, stainless steel belt and stainless steel pipe for a long time. The designated products are complete and the quality is guaranteed. For example, 50a470 means that the thickness is 0.5mm and the iron loss guarantee value is ≤ 7 cold rolled non oriented silicon steel strip.
.Application field: launch the market plan of stainless steel pipe in the target market of new products, such as stainless steel kitchen equipment.
4: stainless steel strip (stainless steel coil): or coil, coil, coil, plate coil. There are many names and the hardness of the strip varies from dozens to hundreds. The customer needs to determine which hardness to use first. (8K mirror luminosity)
. 303— Add a small amount of sulfur and phosphorus to make it easier to cut.
500 Series & mdash; Heat resistant chromium alloy steel.
Theoretical weight of stainless steel pipe: w = outer diameter - wall thickness x wall thickness x0.02491.
Cutting tool level & rdquo; Martensitic steel, an early stainless steel similar to Brinell high chromium steel. It is also used for surgical tools, which can be made very bright.
Application: utility boiler industry, mainly in key parts such as high temperature section of superheater and reheater.
If packing is not required, it shall be indicated in the contract and will not bear the problem of scratching and scratching the surface of stainless steel pipe due to opening the packing bag.
Quality documents.The power supply with vertical external characteristics is adopted,1Cr13 stainless steel pipe, and the positive polarity is adopted in DC (the welding wire is connected to the negative pole).
The resistance, linear coefficient, thermal conductivity, quality, hot melt and magnetism of stainless steel pipe will change greatly at low temperature. Resistance, line coefficient decreases at low temperature; The thermal conductivity and mass heat capacity decrease sharply at low temperature; Young's modulus (longitudinal modulus) increases when the temperature decreases. Because the austenitic series stainless steel pipe has MS point (martensite start temperature or martensite formation temperature) at low temperature (subzreo temperature), martensite can be formed when it is kept below MS point. The formation of martensite at low temperature makes the representative steel sus (18Cr-8Ni) of austenitic stainless steel non-magnetic at room temperature and magnetic at low temperature.
The stainless steel pipe installed on the pipeline support can be corroded by 200 ppm chloride ion and 2 ppm residual chlorine in an aerobic environment. For carbon steel structural supports, the pipeline shall be insulated to prevent corrosion due to potential difference, never use glue and other materials that contain chloride ions halogens and other corrosive effects on stainless steel pipes.
In addition, its service time, quality and stiffness should be considered, and the strength requirements of the plate under pressure should be considered; Thermal conductivity; Distribution of pressure and format specification of pressing plate.
Highly recommended. ≥205TS（Mpa）
Household worries.
5: stainless steel wire: it can also be called stainless steel wire, but it is different from stainless steel wire rope. Wire rod mainly includes spring wire and screw wire, professional stainless steel plate stainless steel coil,316 stainless steel pipe, stainless steel belt, The spring wire is used to make springs or other hardware products required. Others, such as bright wire, hydrogen withdrawal wire, electrolytic wire, axle hairpin wire, etc. the tensile strength is 1500-2000. The hardness of spring wire is as follows: fully soft | 1 / 4 hard | semi hard | 3 / 4 hard | fully hard | extra hard. Steel wire rope gauge: 7 * 1,6 * 12,7 * 7,7 * 19,17 * 39, etc., which is higher than that of wires, rods and tubes of the same material 304 stainless steel is a kind of high alloy steel that can corrode in air or chemical corrosion medium. Stainless steel has beautiful surface and good corrosion resistance. It does not have to go through surface treatment such as color plating, but gives full play to the inherent surface properties of stainless steel. It is used in many aspects of steel, which is usually called stainless steel. Representative properties include 13 chromium steel, 18-8 chromium nickel steel and other high alloy steels.
.The application of stainless steel pipe in the automobile industry is developing rapidly. In recent ten years, stainless steel pipe materials have been widely used in public transportation tools such as buses, subways, high-speed railway vehicles, household cars and so on!
In order to prevent the occurrence of welding pores, the welding parts must be cleaned if there is rust, oil stain, etc.
Clamping operation the jaw of the caliper must be placed perpendicular to the axis of the pipe and pipe fitting, and the convex ring of the pipe fitting needs to be put into the groove of the jaw for clamping. In order to prevent operation, the operator can only stand on the axis of the pipe, not on the left and right sides of the tong head.
