Q:Stainless steel wire drawing without fingerprints, what principle?
Let's say the principle: the material surface is easy to leave the fingerprint because the material has the characteristics of specular reflection on the light. The material is smooth enough, and the light is not diffusely reflective on the material, mainly specular. Landlord with your finger press the glass mirror will know
Q:304 why is stainless steel magnetic?
304 stainless steel after cold processing, the structure of the structure will also change to martensite, and the greater the deformation degree of cold work, the more martensite transformation, the greater the magnetism. Like a lot of stainless steel wire, made straight, no obvious induction, but it is bent into a rectangular or circular, and produce some magnetic for cold bending deformation is large, especially the angle of magnetic is more obvious.In order to eliminate the magnetism of the 304 stainless steel, the austenite structure can be recovered by high temperature treatment so as to eliminate magnetism.Special remind is, 304 magnetic stainless steel because it causes, and other materials such as stainless steel, carbon steel, magnetic 430 is not the same level, that is to say the magnetic stainless steel 304 is always weakly magnetic.
Q:Stainless steel sheet welding method, thickness of 0.5mm
Common welding method: pulse DC TIG welding.
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:Stainless steel plate laser cutting how to charge?
It depends on which laser machine you use, and the specific model, and the processing materials are also different. Consumption is mainly: electricity, laser gas, auxiliary gas, consumables, general machine tool software has billing function, but not allowed.
Q:430 stainless steel plate maximum temperature tolerance is how many degrees?
430 stainless steel plate is 430 stainless steel sheet shaped products. 430 stainless steel plate according to the thickness can be divided into thin plate, medium plate, thick plate and other forms; at present the maximum width of up to 2000mm, length is not limited.
Q:Advantages and disadvantages of stainless steel
1. Chemical properties: resistance to chemical corrosion and electrochemical corrosion resistance in steel is the best, second only to titanium alloy.2, physical properties: high temperature resistant, low temperature resistant and anti cold also.
Q:Welding defects analysis of 1.5mm stainless steel plate
BurnthroughReasons: 1. The welding current is too large;The welding parts overheated;3 butt gap is too large;The welding arc is slow, long residence time.Hazard: 1. Poor surface qualityThe burn below often have pores slag pits.
Q:What does stainless steel sheet S2 stand for?
It is an alloy steel which is not easily rusted, but it is not absolutely rusty. Stainless steel plate refers to the atmosphere, steam and water and other weak medium corrosion of steel plate, and acid resistant steel plate refers to acid, alkali, salt and other chemical corrosive medium corrosion of steel plate. Stainless steel plate has been published since the beginning of twentieth Century, and now has a history of more than 1 centuries.
Q:What's the difference between galvanized steel and stainless steel?
Stainless steel is often divided into martensitic steel, ferritic steel, austenitic steel, austenitic ferrite (duplex) stainless steel and precipitation hardening stainless steel according to the state of the organization. In addition, can be divided into components: chromium stainless steel, chromium nickel stainless steel and chromium, manganese, nitrogen, stainless steel and so on.
