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:What kind of stainless steel square tube is used in ordinary square tubes?
Stainless steel square tube is a kind of hollow long strip steel, because the section is square, so it is called square pipe. As the 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.
Q:How can stainless steel and copper pipe be welded?
Prepare a brass wire cleaning flux of base metal 3/4 stainless steel tube 5/8 copper rust (specific parent material specification is not clear to me) welding tools
Q:Stainless steel heating oven tube after treatment is heating blue will not be red?
When the power is not enough, his argument is clearly untenable, and technology is a kind of metal surface treatment. Heating 250 degrees is not red, can not say is not normal, only can meet your work requirements, no problem.
Q:Can magnets attract stainless steel tubes?
Stainless steel is becoming more and more popular because of its beautiful appearance, corrosion resistance and not easy to damage. More and more pots, city sculpture, architecture, decoration room etc. the use of stainless steel, stainless steel on discrimination but people do not know, some customers buy stainless steel kitchenware, stainless steel utensils with magnets in to try to try. It is stainless steel that attracts the magnet, but stainless steel can not be sucked. It seems that there is a misunderstanding about stainless steel.
Q:The difference between galvanized steel pipe and stainless steel pipe
Stainless steel pipe is a kind of hollow long strip round steel, mainly used in petroleum, chemical, medical, food, light industry, machinery, instrument and other industrial pipeline and mechanical structure parts. In addition, the bending and torsional strength of the same weight is lighter, so it is also widely used in the manufacture of mechanical parts and engineering structures. It is also used to produce all kinds of conventional weapons, guns, shells and so on.
Q:Where is the difference between seamles steel pipe and welded pipe?
Seamless steel tube: seamless steel pipe is made of steel ingot or solid tube blank through piercing, then made by hot rolling, cold rolling or cold casting. Specifications for seamless steel tubes are expressed in millimeters of outer diameter * wall thickness. Seamless steel pipe, hot-rolled and cold-rolled (DIAL) seamless steel pipe two categories.Hot rolled seamless steel tubes are divided into ordinary steel tubes, low and medium pressure boiler tubes, high pressure boiler tubes, alloy steel tubes, stainless steel pipes, oil cracking pipes, geological steel pipes and other steel pipes, etc..
Q:Where is the difference between seamless steel pipe or welded pipe?
Seamless steel tube is formed during rolling. Welded steel pipes need to be welded after coiling, and spiral welding and direct welding are generally used. Seamless performance is better, of course, the price is higher.
Q:What is the difference between stainless steel tube 304L and 304N?
The lower carbon content minimizes the precipitation of carbides in the heat affected zone near the weld, while the precipitation of the carbides may lead to intergranular corrosion in stainless steels in certain environments.
Q:What is the welding of stainless steel?
Many welding methods, commonly used argon arc welding, less thermal stress, less molten metal elements, forming beautiful; the remaining manual arc welding, higher requirements can be used when laser welding
