Q:Stainless steel pipe drilling?
Stainless steel itself is not high hardness, but it is difficult to processing reasons:Because the stainless steel contains C element is low, hardness is not high, and not easy to deformation, plasticity is poor, this is the iron and steel organization grain concentration caused by. This allows the drill to increase its viscosity when drilling, and it is not easy to chip out. The drill is easy to burn at this time. Through the practice comparison, we know that the opening of 135 degree bit is much easier when the control speed is 300-500 to /min. It is much easier than the drilling of 118 degree hole on the same material.
Q:304 stainless steel seamless tube weight how to calculate?
The common marking methods in the market are 00Cr19Ni10, SUS304, in which 00Cr19Ni10 is generally used to indicate standard production of the national standard. Generally speaking, ASTM standard production is indicated, and SUS 304 represents standard production.
Q:Under what circumstances can the stainless steel pipe be welded by argon arc, and under what conditions can the arc welding be used?
From the economic point of view and flexibility, arc welding is good, from the efficiency aspect, of course, argon arc welding is higher, the effect is better, and also more mechanized. If it is small batch, it will choose arc welding.
Q:What are the categories of stainless steel pipes with acid and alkali resistance?
Austenitic stainless steel is the stainless steel with austenite structure at normal temperature. When the steel containing Cr is about 18%, Ni, 8%~25% and C is about 0.1%, it has a stable austenite structure. Austenitic chromium nickel stainless steel includes the famous 18Cr-8Ni steel, and on this basis, increasing the content of Cr, Ni, and adding Mo, Cu, Si, Nb, Ti and other elements developed by the high Cr-Ni series steel. Non magnetic austenitic stainless steel with high toughness and plasticity, but the intensity is low, not through the phase change to strengthen, can only be strengthened by cold working, such as adding S, Ca, Se, Te and other elements, it has good machinability. Good comprehensive performance, corrosion resistant variety of media.To prevent intergranular corrosion, this kind of stainless steel is usually low carbon or ultra low carbon.
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:Does stainless steel pipe belong to hardware?
Hardware refers to gold, silver, copper, iron, tin, five kinds of metal materials, carbon steel and stainless steel is iron upgrade, naturally belongs to the hardware.
Q:Stainless steel pipe welding interface leakage, how can we not leak?
Only when the welding quality is improved and the welding defects are reduced can the welding seam position be watertight:Argon arc welding is preferred for stainless steel pipe welding. When the wall thickness is thicker, the backing argon arc welding shall be used preferentially, and the filling and cover surface shall be welded by manual arc welding;The cleaning work before welding should be done well, and all the defects such as burr, oil stain, dust and spot welding should be removed;
Q:What color is stainless steel? What color is stainless steel pipe culture?
You want to draw the stainless steel, or to mirror the drawing, usually gray, mirror is generally bright silver, of course, the color is also there, ah, you need it
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:What is the difference between stainless steel seamless tube and stainless steel welded pipe?
Stainless steel welded pipe is also a hollow section of steel, but it is welded through the plate into the steel pipe, so there is a welded steel pipe welding gap.
