Q:What's the difference between stainless steel 304 and stainless steel 202?
Different chemical composition. 304 of the nickel is much higher than 202.
Q:Stainless steel pipe is mainly used in what areas?
The stainless steel pipe is a kind of economic section steel, is one of the most important products in the steel industry, which can be widely used in industrial and living decoration on the market, a lot of people for the production of staircase handrails, railings, window, furniture etc.. There are two kinds of materials, 201 and 304.
Q:What's the difference between stainless steel decorative pipes and polished stainless steel pipes?
Stainless steel decorative tubes are mostly stainless, iron does not contain nickel, and so on, the material is slightly worse. Mainly used for interior decoration, such as interior railings, stair guards and railings, windows and so on, the thickness of the steel pipe is generally relatively thin.
Q:How about stainless steel 2520 and 316?
2520 stainless steel (310S) austenitic chromium nickel stainless steel has good oxidation resistance, corrosion resistance, because of higher content of chromium and nickel content, which has high temperature creep strength, can continuously work under high temperature, good heat resistance. For Ni (Ni), chromium (Cr) content is high, with good oxidation resistance, corrosion resistance, acid and salt, high temperature performance, high temperature resistant steel dedicated to the manufacture of electric furnace tube and so on, increase the amount of carbon austenitic stainless steel, due to the solid solution strengthening effect to the strength improved, chemical composition characteristics of austenitic stainless steel is chrome, nickel based addition of molybdenum and tungsten, niobium and titanium elements, as its face centered cubic structure, and strength and high creep strength at high temperature.
Q:What is the welding of stainless steel?
If batch welding, it is recommended to use laser welding, welding heat affected area is small, weld appearance, speed, more suitable for thin plate,
Q:SA-179 what kind of material is steel pipe?
SA179 corresponds to China's material is GB8163 10# seamless steel pipe.
Q:Stainless steel tube, also known as why tube
According to the end of the pipe can be divided into light pipe and wire tubeThe tube can be divided into ordinary tube and special thread tube
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
Q:Stainless steel heating oven tube after treatment is heating blue will not be red?
Because sometimes we do tubular heater, in order to better improve its life, will reduce the heating pipe surface power, but it itself heating speed is slow, take more time to reach the temperature you want.
Q:304 stainless steel pipe, 20*2 pressure, how many kilograms?
304 yield strength is 210 R=, thickness D=, outer diameter, P=210/20=10.5, MPa, 1MPa=10, KG, can withstand 105 kg.
