Q:What's the difference between stainless steel 304 and stainless steel 202?
202 stainless steel is one of the 200 series stainless steel, the national standard model is 1Cr18Mn8Ni5N. 200 series stainless steel is low nickel, high manganese stainless steel, nickel content, manganese content of about 8%, is a nickel type stainless steel.
Q:Mechanical properties of stainless steel tubes
High temperature fatigue is the process of damage to fracture due to repeated stress changes in the material at high temperature. The results show that, at a certain high temperature, the fatigue strength of the 8 power high temperature of 10 is 1/2 of the high temperature tensile strength at this temperature.
Q:Disadvantages of stainless steel tubes
Aluminum plastic composite pipe is a kind of pipe material that is more popular at present. Because of its light weight, durability and convenient construction, it is more suitable to be used in home decoration. The main drawback is that when used as a hot water pipe, due to long-term thermal expansion and cold contraction, it will cause the wall of the pipe to be dislocated so as to cause leakage.
Q:Stainless steel pipe specification 25*2 what does it mean?
Phi 25*2 indicates that the outer diameter is 25mm and the wall thickness is 2mm. This is a small tube
Q:Stainless steel pipe 301 material and 304 material what is the difference?
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)
Q:Why does the 304 stainless steel pipe leak?
Chloride poisoning. Why chlorine is found in tap water is not explained here.
Q:Stainless steel and stainless steel pipe inside and outside polishing off, what is the difference?
Ordinary stainless steel is in the chemical grade, and the ordinary pickling surface looks white. Mainly used in petrochemical, sewage treatment and other industries.
Q:Is food grade stainless steel GB9684 304?
Food grade stainless steel is in line with the GB9684 standard stainless steel.
Q:Why pickling before cleaning stainless steel pipe oil?
On the premise of oxide, a good foundation for the formation of passive film is made, which makes the passivation film more compact and improves the passivation effect!
Q:How can stainless steel and copper pipe be welded?
First, try the test before burning. The brass is directly burned to the stainless steel tube. First feel the heat and see what the stainless steel likes to adhere toWhen stainless steel is not red, copper is not adheredWhen stainless steel is red, do not stick copperOnly when stainless steel is red, copper paste is preferredTherefore, when welding, we must master the size of the furnace, thin and thin pipe, fire should be adjusted to small crude pipe, on the contrary, they feel the proper heat
