Q:Stainless steel pipe 301 material and 304 material what is the difference?
On the surface, hardness is the test, then the material is NI, the difference is so small, the overall price is almost the same. Now, there are a lot of non German, this guy played with 301, when 304 sold.
Q:Is food grade stainless steel GB9684 304?
304 stainless steel is a very common stainless steel, the industry is also called 18/8 stainless steel. It is better than the corrosion resistance of 430 stainless steel, high temperature corrosion resistance, good processing performance, so it is widely used in industrial and medical furniture industry and the food industry, for example, some high-grade stainless steel tableware, bathroom and kitchen utensils. 304 is a versatile stainless steel which is widely used in the manufacture of equipment and parts requiring good overall performance (corrosion resistance and formability). In order to maintain the inherent corrosion resistance of stainless steel, steel must contain more than 17% chromium, more than 8% of the nickel content. General 304 stainless steel is not food grade, specially processed is food grade.
Q:Disadvantages of stainless steel tubes
Stainless steel composite pipe and aluminum plastic composite pipe in the structure of almost, to some extent, the performance is also relatively close. Similarly, due to the strength of the steel, the construction process is still a problem.
Q:304 stainless steel, welded to seamless difference in what place?
Chemical composition of seamed pipe and seamless pipe are different. The production of seamless steel components only meets the basic requirements of astm. The production of seamed tube steel containing suitable for chemical composition of welding. For example, the mixing of silicon, sulfur, manganese, oxygen, and a certain proportion of elements such as the triangle ferrite can produce a welding flux which is easy to transfer heat during welding, so as to make the whole weld be welded well. The lack of steel pipe above the chemical components, such as seamless tube, can produce all kinds of unstable factors in the process of welding, welding and welding penetration is not easy.
Q:316 stainless steel pipe wall mirror polishing, the smaller the roughness, the better.
Sanitary grade stainless steel tube and stainless steel sanitary pipe: phi 6 - 219mm * 0.5 - 5mm. The product is cold rolled by three roll tube mill and is polished inside and outside by degreasing and flat drawing. It is a seamless sanitary stainless steel pipe and stainless steel sanitary pipe finished product. The outer surface of the product is polished, the diameter and wall thickness tolerance of less than 0.02-0.05mm, the inner wall of the pipe roughness Ra is less than or equal to 0.6 m after Ra or 0.4-0.25 inner wall polishing m, sanitary stainless steel pipe and stainless steel pipe health features: inside and outside wall of polished, bright surface, very smooth, high dimensional accuracy, delivery status generally hard (micro magnetic), and widely used.
Q:What factory uses industrial stainless steel tube to be more?
For equipment manufacturing and maintenance, etc., the annual consumption of stainless steel pipe more than 20000 tons. Such industries mainly use sanitary or antibacterial grade stainless steel tube.
Q:Stainless steel pipe is mainly used in what areas?
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:Are stainless steel tubes and galvanized steel tubes the same?
It's quite different!The stainless steel pipe itself is made of stainless steel, and galvanized steel pipe is coated with zinc on the surface of the carbon steel tube
Q:304 stainless steel will rust it?
General stainless steel chromium content is generally not less than 12%, high even up to 18%. When chromium is added to the steel, the properties of the steel can be changed. For example, the molecular structure of the steel is more uniform, and the surface of the steel is easy to produce a layer of dense oxide protective film, which greatly improves the corrosion resistance of the 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:Stainless steel pipe chamfering how to process?
If the amount of larger or longer steel pipe, you can buy a dedicated handheld steel pipe chamfering tool, called "steel chamfering machine"". This is much more efficient than using a lathe
