Q:What are the categories of stainless steel pipes with acid and alkali resistance?
Stainless steel is mainly used for acid resistance, alkali resistance is not necessarily very prominent.
Q:Stainless steel tube, also known as why tube
It can be divided into round tube and special-shaped tube according to the cross sectional shapeThe special-shaped tube has a rectangular tube, a rhombus tube, an elliptical tube, six square tubes, eight square tubes, various cross section asymmetric pipes, etc.
Q:What's the difference between stainless steel 302 or 304?
[difference] 302 stainless steel and 304 stainless steel 304 stainless steel is one of the most widely used kind of chromium - nickel stainless steel, as a widely used steel, corrosion resistance, good heat resistance, low temperature strength and mechanical properties; punching, bending and other thermal processing, non hardening heat treatment (using temperature -196 to 800 DEG C). 302 stainless steel the carbon is relatively high (302 C = 0.15%; 304 C is less than or equal to 0.08%) and better strength. The other indicators are basically the same as those of 304.
Q:What are the differences in the properties of hot-rolled and cold-rolled stainless steel tubes?
From the current market, cold working processing method has been basically eliminated the hot working mode, this is caused by defects in thermal processing of stainless steel pipe: thermal processing of stainless steel tube, as in the case of heating, a molding, molding the mechanical properties of the stainless steel tube is relatively poor, so the tube doing mechanical processing will often cannot meet the needs of mechanical and physical properties.
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:Under what circumstances can the stainless steel pipe be welded by argon arc, and under what conditions can the arc welding be used?
The quality of argon arc welding is high, the efficiency is low, the efficiency of SMAW is relatively high, the quality of secondary pipe welding, general thick such as 10mm are TIG welding, welding rod filler cover, if the pipe is thin directly by argon arc welding
Q:304 stainless steel has several advantages, a few big advantages, the more concrete the better
304 stainless steel advantages:1. environmental sanitation: put an end to red water, blue green water, and hidden water problems, no peculiar smell, no harmful substances, keep the water quality pure, lead free, harmless to human health.2., wear resistance: beautiful surface, clean and bright, long lasting, no scratches, never rust, never break. 3., low temperature: kitchen, bathroom, stainless steel water pipe, faucet angle valve will never break.4., thermal expansion and excellent insulation performance: stainless steel tube has expansion, cold contraction, slow insulation performance.5. authority certification: stainless steel metal element precipitation than WHO and European drinking water act standard value of 5% is still lower.
Q:Mirror stainless steel tube 60*60 how much is one meter?
Stainless steel tube square weight formula: (pipe circumference / 3.14- actual thickness) * actual thickness *0.02491* length, 0.02491 of which is converted by the stainless steel density of a constant.
Q:What color is stainless steel? What color is stainless steel pipe culture?
Stainless steel is usually silver, also has colored stainless steel
Q:Stainless steel welded pipe or seamless pipe expensive?
From the brand can understand: domestic grade Cr smaller numbers are more expensive, the sum of Cr after the larger the number the more expensive, more expensive Cr symbols and so on. Foreign steel also has some rules: such as the stainless steel, the same series of numbers of bigger, longer, more expensive and more letters.
