Q:What's the difference between stainless steel hot rolling and cold rolling?
Cold rolling: it is rolled and rolled on the basis of hot rolled stainless steel plate and coil. Generally speaking, it is the process of hot rolling, pickling and cold rolling. Although the rolling process also causes the steel plate to heat up during the process, it is called cold rolling. Because of the cold rolling of continuous hot rolling, the mechanical properties are poor and the hardness is too high. It must be annealed to restore its mechanical properties. Rolled rolls are generally used to make products without bending or stretching.
Q:304 stainless steel plate surface quality inspection method which has several?
Attachment of cold processing such as workpiece surface lubrication oil, must be fully skimmed in trichloroethylene degreasing agent, caustic soda solution and then with warm water washing, and then heat treatment. Stainless steel plate, if the surface of debris, especially organic matter or ash attached to the workpiece, heating, of course, will have an impact on the oxide skin. Stainless steel plate furnace atmosphere difference, furnace atmosphere in each part of the different, the formation of oxide skin will change, and this is also caused by uneven acid cleaning reasons. Therefore, when heating, the atmosphere in each part of the furnace must be the same. For this reason, the cycle of atmosphere must also be taken into account. Also, a heating workpiece with bench brick, asbestos, if contain water, when heated, water will evaporate, differences in direct contact with the water vapor and other parts of the atmosphere will produce, the formation of oxide of course is different. Therefore, objects that are in direct contact with the heating workpiece must be thoroughly dried before use. However, after drying, such as placed at room temperature, moisture in high conditions, the water will still condense on the surface of the workpiece. So, it's better to dry before use. If the local processing of stainless steel plate before heat treatment with oxide remaining, after heating with oxide remaining parts and parts without oxide, differences in composition and thickness of oxide skin will appear on the surface after pickling caused by uneven, so we should not only pay attention to the final heat treatment, but also to the full note that the middle heat treatment and pickling. There is a difference between the surface of stainless steel and the place where it is not touched.
Q:What is the difference between stainless steel coil or stainless steel plate?
The chemical resistance of the medium (acid, alkali, salt and other chemical etching) corrosion of steel called acid resistant steel. Because of the difference in the chemical composition of the two, and make their corrosion resistance is different, ordinary stainless steel is generally not resistant to chemical medium corrosion, and acid resistant steel are generally stainless steel.
Q:Welding defects analysis of 1.5mm stainless steel plate
Shape defects - the appearance quality is rough; the wave height and width of the fish scales change abruptly; the welding seam and the parent material are not smooth transition.The main reason is improper operation, repair caused.The damage is stress concentration, weakening the carrying capacity.Weld size defectThe size does not conform to the construction drawings or technical requirements.The main reason is the improper operation of the builderHazard: small size, small load cross section;The large size weakens the fatigue strength of some structures subjected to dynamic loads.
Q:What glue does the board or the stainless steel stick to?
Application of epoxy resin adhesive is widely used in bonding of various metals and alloys, ceramics, glass, wood, cardboard, plastic, concrete, stone, bamboo and other non-metal materials, or bonding of metal and non-metallic materials. For untreated polyethylene, polypropylene, PTFE, polystyrene, PVC and other plastic without adhesion, for rubber, leather, fabric and other soft material adhesive ability is also poor.
Q:How can I classify stainless steel plates?
The stainless steel plate in accordance with the classification of surface features can be divided into: silver white matte (use does not need to have a surface gloss), bright as a mirror (building materials, kitchen utensils), coarse grinding fine grinding / polishing / intermediate / fine grinding (building materials, kitchen utensils), hairline grinding (buildings, building materials), close to the mirror grinding (art, decoration), mirror grinding (mirror, decorative).
Q:What is the area of stainless steel plate?
For example, a steel coil with known weight, thickness, length, width, and price, you can work out the cost price of each meter, and then you can set the price as you expect it
Q:What's the difference between 304 stainless steel and 314?
304 stainless steel is a universal stainless steel material: 314 stainless steel; high temperature oxidation resistance and strong mechanical properties; high heat resistant stainless steel, and 314 austenitic stainless steel, high temperature oxidation resistance and creep resistance. 314 stainless steel used in furnace tube difference
Q:What is the general width range of stainless steel sheet? What are the common widths?
According to the agreement can be scheduled to open, usually to add money, commonly used thin 3mm below the general specifications commonly used, 1000*20001219*2438, 3mm or more commonly used specifications 1500*6000.
Q:What is the difference between stainless steel 302 and 304?
Plate type heat exchanger, corrugated pipe, household appliances (1, 2 kinds of tableware, kitchen cabinet, indoor pipeline, water heater, boiler, bath), auto parts (windshield wiper, muffler, mold), medical appliances, building materials, chemical, food industry, agriculture, marine parts, millet mobile phone etc.. 304 stainless steel is a nationally recognized food grade stainless steel.
