Q:304 stainless steel will rust it?
Why is stainless steel rust? When the stainless steel tube surface appear brown rust (point) when people are surprised: "the stainless steel does not rust, rust is stainless steel, steel may be a problem". In fact, this is a lack of understanding of stainless steel one-sided misconceptions. Stainless steel will rust under certain conditions.
Q:Water and electricity thin wall stainless steel tube 304 material delta 2 what does that mean?
304 stainless steel is a universal stainless steel material, antirust performance than the 200 series of stainless steel material stronger.
Q:How about stainless steel 2520 and 316?
316 stainless steel by adding Mo element, the corrosion resistance, and high temperature strength has greatly improved, high temperature can reach 1200-1300 degrees, can be used in severe conditions. Uses: marine equipment, chemicals, dyes, paper, oxalic acid, fertilizer and other production equipment; photography, food industry, coastal facilities, ropes, CD poles, bolts, nuts.
Q:304 stainless steel has several advantages, a few big advantages, the more concrete the better
304 stainless steel is a universal stainless steel material, antirust performance than the 200 series of stainless steel material stronger. High temperature resistance is also good, the general use of temperature limit is less than 650 degrees centigrade.
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:Stainless steel pipes can not be less than the amount of chromium
General stainless steel chromium content is generally not less than 12%, high even up to 18%. Steel added elements such as chromium, can change the performance of the steel, such as the molecular structure of steel more uniform on the surface of the steel is more easily to form a layer of dense oxide protective film, thereby greatly improving the ability of corrosion-resistant stainless steel. Therefore, stainless steel can resist fire, water, acid, alkali and various solutions to its corrosion, not rust. The scientists found that the internal structure of the steel is more uniform, various components more closely linked to the corrosion of the more difficult the invasion, also attached to the surface with a layer of oxide film, like iron and steel to wear armor, was not naturally easy to rust. Why is stainless steel rust? When the stainless steel tube surface appear brown rust (point) when people are surprised: stainless steel does not rust, rust is stainless steel, steel may be a problem. In fact, this is a lack of understanding of stainless steel one-sided misconceptions. Stainless steel will rust under certain conditions. Stainless steel has the ability to resist atmospheric oxidation - that is, stainless steel, and also has the ability to corrode in medium containing acids, alkalis, and salts - that is, corrosion resistance. But its corrosion resistance is changed with the chemical composition, the mutual state, the condition of use and the type of environmental medium.
Q:Ask experts, 304 stainless steel pipe why rust?
304 stainless steel is a common stainless steel material, the density of 7.93 g/cm3, the industry is also called 18/8 stainless steel. High temperature resistance of 800 degrees, with good processability, high toughness characteristics, widely used in industry and furniture decoration industry and food and medical industry.The common marking methods in the market are 06Cr19Ni10, SUS304, in which 06Cr19Ni10 is generally used to indicate standard production of the national standard. Generally speaking, ASTM standard production is indicated, and SUS 304 represents standard production.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). In order to maintain the inherent corrosion resistance of stainless steel, steel must contain more than 18% chromium, more than 8% of the nickel content. 304 stainless steel is a brand of stainless steel produced according to the ASTM standard in the United states.
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 connecting methods of stainless steel pipes for indoor water pipes?
Card convex features: easy installation, the connection is not deformed inside and outside, belong to live connection, easy maintenance. Scope of application: cold water system, pipe direct drinking water system, water treatment equipment system. The installation is more suitable, mainly taking into account the replacement of the sealing ring later, the hot water system should be avoided as far as possible. The advantage of the connection is that the installation is simple, convenient and easy to maintain, and the sealing ring in the pipe needs replacing when aging, and the utility model is relatively simple and convenient, and the nut can be replaced as long as the nut is unscrewed. The disadvantage is that the applicable situation is single, in the hot water system sealing ring aging is more prominent, higher cost. Concealed piping and hot water systems are generally not recommended.
Q:Comparison of ring type connection and argon arc welding of stainless steel pipe
Characteristics of argon arc welding of stainless steel pipe:1. Permanent structure, reliable quality;2. Reduce the number of parts used;3. The construction technology is relatively complicated.
