Q:Stainless steel pipe drilling?
General requirements for processing stainless steel workpiece hole smooth, less burr, white technology generally choose high-quality grinding drill, on the market are mostly black rolling process, the main difference between full grinding and rolling process is drilling with the drill chuck supporting the overall use of small amplitude and hole grinding, less burr, the accuracy is high especially, when batch processing efficiency.
Q:Ask experts, 304 stainless steel pipe why rust?
Stainless steel is not easy to rust and has a lot to do with the composition of stainless steel. In addition to iron, stainless steel contains chromium, nickel, aluminum, silicon and so on. General stainless steel chromium content is generally not less than 12%, high even up to 18%. Steel added elements such as chromium, can change the performance of the steel, such as the molecular structure of steel more uniform on the surface of the steel is more easily to form a layer of dense oxide protective film, thereby greatly improving the ability of corrosion-resistant stainless steel. Therefore, stainless steel can resist fire, water, acid, alkali and various solutions to its corrosion, not rust. The scientists found that the internal structure of the steel is more uniform, various components more closely linked to the corrosion of the more difficult the invasion, also attached to the surface with a layer of oxide film, like iron and steel to wear armor, was not naturally easy to rust.
Q:Classification, advantages and disadvantages of stainless steel welding
The arc is produced between the tungsten welding wire and the workpiece, so the protection gas is pure argon and the welding wire is not charged, so it can be sent by hand or by machine. Then it is whether to use direct current or alternating current, depending on the welding material.
Q:Why can't stainless steel tubes be cut with acetylene?
Is mainly from Huoxian, heating flame is mainly open before cutting and cutting plate preheating on the auxiliary heating.Stainless steel, chromium containing at least 13% or more, it hinders the exothermic oxidation and melting phenomenon, which is higher than that of iron chromium to 316 degrees, 1855 degrees, so can not use stainless steel oxygen - acetylene flame cutting.
Q:Where is the difference between seamless steel pipe or welded pipe?
The steel tube is a hollow steel strip, used as pipe conveying fluid, such as oil, gas, water, gas, steam, in addition, the bending and torsional strength of the same, the weight is light, so it is widely used in the manufacture of machinery parts and engineering structures. It is also used to produce all kinds of conventional weapons, guns, shells and so on.
Q:What is the difference between stainless steel tube 304L and 304N?
304L is a variety of 304 stainless steel with low carbon content, used for occasions where welding is required.
Q:Water and electricity thin wall stainless steel tube 304 material delta 2 what does that mean?
304 is a stainless steel number, 2.9 refers to the pipe wall thickness.
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?
There is no essential difference between 316SS and 316L, the same as austenitic stainless steel, and SS means stainless steel.316SS and 316L stainless steels are made of Mo stainless steel. The total performance of this steel is better than that of 310 and 304 stainless steel. Under high temperature, 316 stainless steel is widely used when the concentration of sulfuric acid is below 15% and higher than 85%. 316 stainless steel also has good chloride corrosion resistance, so it is often used in marine environments.
Q:Stainless steel pipe pickling ratio
Usage: apply proper amount of this product onto the surface of stainless steel to be processed, the thickness of 1~2 mm, 5-30 minutes or longer (by dirt, sheet materials and processing requirements), process the best brush a few times, the surface oxide skin, rust completely clean, with water (lime water or salt water better) rinse, avoid rust.
Q:What are the differences in the properties of hot-rolled and cold-rolled stainless steel tubes?
Stainless steel tube with hot and cold points, hot rolling is made by stainless steel tube billet heated to red state, through processing a mold, which is cold-rolled stainless steel pipe billet collocation through different mould at room temperature, finally by drawing rolling method, stainless steel tube working together the size of the need to.
