- Q:Why is stainless steel magnetic?
- There are kinds of stainless steel at room temperature, the organizational structure can be divided into several categories: 1. austenitic: such as 304, 321, 316, 310; 2. martensite or ferrite, such as 430, 420, 410; austenitic is non-magnetic or weak magnetic properties, martensite or ferrite is magnetic. Usually used as a decorative stainless steel pipe,Most of the stainless steel plate is Austenitic 304 stainless steel material, is generally non-magnetic or weakly magnetic, but fluctuations in chemical composition caused by smelting or processing of different magnetic properties may also appear, but this can not be considered to be counterfeit or substandard, what is the reason? The above mentioned austenite is non-magnetic or weakly magnetic, and martensite or ferrite is magnetic, due to melting segregation or improper heat treatment, will cause a small amount of martensite Austenitic 304 stainless steel body or ferrite.
- 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:304L stainless steel pipe can withstand 0.1MPA?
- If you want to know how much pressure the steel pipe is under, you need to know the type of the stainless steel pipe.Pressure calculation formula of stainless steel management: pressure MPA=, tensile strength X40%X2X, wall thickness / outer diameterBut from my experience, generally speaking, stainless steel tubes can withstand 0. 1MPA. Unless it is used very thin stainless steel tube wall decoration.
- Q:Are stainless steel pipelines buried in need of corrosion protection?
- The factors of the material itself: stainless steel pipe structure exists because of the equipment, or the existence of cracks of metal or non-metal deposits on the surface, in the sediment and the stainless steel tube surface in the formation of cracks, corrosion, will give priority to produce punctate and ulcer like damage in the crevice, which is crevice corrosion.
- Q:Stainless steel seamless steel tube, ordinary seamless steel pipe, which is good?
- Stainless steel pipe in the nickel element is relatively high, nickel is pipe rust proof, wear-resistant, mainly corrosion-resistant. The strength of the steel pipe is generally related to the content of carbon in the pipe. The ordinary steel pipe is carbon steel pipe, and the compressive strength is generally better than that of the stainless steel tube.
- Q:Are stainless steel tubes and galvanized steel tubes the same?
- Galvanized steel pipe is common steel pipe, and then the surface coated with a layer of zinc coating, in order to prevent rust, as long as the surface layer is ground, it will rust.
- Q:Difference between stainless steel and steel pipe
- Steel pipe according to the production method can be divided into two categories: seamless steel pipe and pipe joints, pipe joints as welded steel pipe.1. seamless steel tube according to the production methods can be divided into: hot-rolled seamless pipe, cold drawn tube, precision steel tube, heat expansion tube, cold spinning tube and extrusion tube.Seamless steel tubes are made of high quality carbon or alloy steel. They are hot-rolled and cold-rolled (drawn).
- Q:Water and electricity thin wall stainless steel tube 304 material delta 2 what does that mean?
- High temperature resistance is also good, the general use of temperature limit is less than 650 degrees centigrade. 304 stainless steel has excellent stainless steel corrosion resistance and better intergranular corrosion resistance. Delta 2 indicates wall thickness of 2 mm
- Q:What does "stainless steel pipe" DN mean?
- Nominal diameter is the size of all piping accessories in the piping system. The nominal diameter is a convenient round integer for reference and is not strictly related to the processing size. The nominal diameter follows the letter "DN" followed by a number sign.
- Q:How can galvanized steel pipe be connected with stainless steel pipe?
- Welding flanges respectively, with flange connection, but galvanized pipe according to specifications, dynamic welding after two times galvanized,
