Q:Lead and stainless steel plate welding together? How do you solder it?
Lead and stainless steel, two different metal elements. Although the welding process is difficult, it can still be welded together.
Q:Stainless steel plate more than the thickness of the wire can not be drawn ah?
Cold can be the basic drawing, cold always have 6, but can also be hot drawing due to the surface, the surface of the hot rolling drawing look is not obvious, many processing plants also willing to help you fill wire drawing, hot rolled board should be relatively large, artificial lift, so drawing up a lot of trouble....12 thick thought it should be no problem
Q:What's the surface of the 304 stainless steel matte board?
Silver white after cold rolling for heat treatment and pickling, and sometimes in the surface roller for the final light rolling of a light surface processing, 2D products used for the surface of the application of lax, general materials, deep stamping materials
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:Are stainless steel plates 3.4mm or 3.5mm thick?
The thickness of less than 1mm of any size 0.05mm times, thickness more than 1mm of any size 0.1mm times;According to standard GB/T 709-2006 hot rolled steel sheet size tolerances, the stainless steel sheet thickness is 3~400mm,
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:Can stainless steel plate spray paint?
Basic treatment, in the future, the film can not be solid, the first process is to first clean the stainless steel surface. The treatment method can use the tool to root out the original paint, and also use sandpaper to polish the surface. It is better to use sand blasting to make the surface clean after roughening, and to increase the adhesion area of the primer.
Q:What is the width of the carbon steel coil and the width of the stainless steel coil, one is 1250, and the other is 1219?
A continuous rolling mill is put in billions of dollars, but this is the rolling mill, and there are many gold furnaces. But the technical content of carbon steel with stainless steel is different, our country in more than 10 years ago the ability of continuous rolling of stainless steel is not high, equipment are imported, the stainless steel mill is dominated by 1219-1300, but also the development of national wide stainless steel 1500-2050, but the price is expensive at least thousands of dollars a ton, after all put the equipment to recover the cost, and the number of business orders is not much, it is difficult to find a spot on the market. Carbon steel countries have developed for many years, technology and equipment are mature, so the market has 1250 as production standards.
Q:What drill can drill stainless steel?
Carbide bit: a drill used in core drilling. The cylindrical steel bit is named after the carbide cutting tool with tungsten carbide. The shape of cemented carbide cutting tools, the number of them arranged on the drill bit, the arrangement and the welding angle are called the bottom, the inner edge and the outer edge, so as to ensure the clearance between the water and the powder. The upper part of the drill body is threaded connection tube, a drill bit body are arranged at the side part of the sink, the bottom surface is provided with a nozzle lip. Both the water tank and the water inlet ensure the circulation of the washing fluid, so as to eliminate the influence of the rock powder and the cooling bit. When drilling into the clay and shale formations, the ribs are welded to the inner and outer sides of the hard alloy drill bit in order to increase the gap, called the rib bit. Self drilling bits with needle like carbide can be used in hard formations with high abrasive properties. Rock drillability is a grade II VII formation general hard alloy drilling; acicular carbide drill drilling a rock grade VI viii.
Q:Welding defects analysis of 1.5mm stainless steel plate
UndercutReasons: 1. The welding parameters do not choose U, I is too large, the welding speed is too slow.The arc is too long. The molten metal failed to fill the melting gap in time.Hazard: the working cross section of base metal decreases and the stress concentration at the undercut is concentrated.
