Q:304L stainless steel pipe can withstand 0.1MPA?
304L stainless steel pipe can withstand 0.1MPAThe pipe can be able to withstand the pressure to see the size, there is the stainless steel seamless pipe pressure is stronger than that of stainless steel pipe joints. 0.1Mpa=10 kg pressure.
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:Why can't stainless steel tubes be cut with acetylene?
To know why stainless steel tubes cannot be cut by acetylene, we must first understand why carbon steel can be cut by oxygen acetylene flame
Q:What are the categories of stainless steel pipes with acid and alkali resistance?
According to corrosion resistance, stainless steel has different alloy composition, commonly used there are ten kinds. According to the composition, roughly classified as chromium and chromium nickel, low carbon and ultra low carbon series.
Q:What is the difference between stainless steel tube 304L and 304N?
304N is a nitrogen containing stainless steel and nitrogen is added to increase the strength of the steel.
Q:310 stainless steel resistance to high temperature?
American brand 310S, also known as 2520, used in high temperature furnace tube manufacturingMain features: austenitic stainless steel
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:What is the welding of stainless steel?
