Q:Classification, advantages and disadvantages of stainless steel welding
The utility model has the advantages of universal use and easy operation, and is mainly regulated by people, and the welding seam material is an electric welding strip. Manual welding can weld almost all of the material, even outdoors, so it has good adaptability and is usually powered by direct current.Welding, either titanium type electrode, can also be sealed. The titanium electrode is easy to weld, the welding seam is beautiful, and the welding slag is easy to remove. But the drawback is that if you do not use it for a long time, you must bake it again to prevent moisture accumulation.
Q:Why does the 304 stainless steel pipe leak?
Austenitic stainless steels are extremely sensitive to chloride ion and can occur in a very short time if the temperature and concentration are appropriate. Therefore, the relevant standards and specifications in the clear requirements for austenitic stainless steel pressure vessels for hydraulic pressure test, there are strict requirements on the chloride ion concentration of the water, and after the test to put water clean, dry. In order to avoid residual moisture in the chloride ion corrosion of stainless steel.
Q:How can stainless steel and copper pipe be welded?
First, try the test before burning. The brass is directly burned to the stainless steel tube. First feel the heat and see what the stainless steel likes to adhere toWhen stainless steel is not red, copper is not adheredWhen stainless steel is red, do not stick copperOnly when stainless steel is red, copper paste is preferredTherefore, when welding, we must master the size of the furnace, thin and thin pipe, fire should be adjusted to small crude pipe, on the contrary, they feel the proper heat
Q:What are the categories of stainless steel pipes with acid and alkali resistance?
Stainless steel is mainly used for acid resistance, alkali resistance is not necessarily very prominent.
Q:In stainless steel tubes, why are there some SS in the back and some standard L, such as 316L and 316SS? What's the difference?
316SS carbon content is higher than 316L (with L indicating ultra low carbon, corrosion resistance of chloride ion, improve its resistance to intergranular corrosion and oxide stress corrosion resistance), mechanical properties,.316SS strength higher than 316L316L is the steel that continues to reduce carbon content on the basis of 316316L is more resistant to corrosion due to its low carbon content
Q:Does stainless steel pipe belong to hardware?
Belong to. Hardware: refers to gold, silver, copper, iron, tin, five metal materials called. Stainless steel pipe is a kind of hollow long strip round steel.
Q:Mirror stainless steel tube 60*60 how much is one meter?
Stainless steel tube square weight formula: (pipe circumference / 3.14- actual thickness) * actual thickness *0.02491* length, 0.02491 of which is converted by the stainless steel density of a constant.
Q:What's the easiest way to distinguish between stainless steel 202 and 304?
They all belong to the austenitic stainless steel, 202 with Mn and N to replace part of nickel, so as to obtain the mechanical properties and good corrosion resistance, is a new type of stainless steel nickel, his strength at room temperature is higher than 304, there are no good oxidation resistance and magnetic strength in medium temperature below 800 degrees. Potions don't fly
Q:How thick is the 3 stainless steel tube?
3 thicknesses representing 3 mm wall thickness
Q:Why can stainless steel pipes be welded by argon arc welding?
Argon protection can isolate the harmful effects of oxygen, nitrogen and hydrogen on the arc and molten pool in the air, and reduce the burning loss of alloy elements, so as to obtain compact, no spatter and high quality welded joints;
