White stainless steel pipe series


Brief introduction of white steel pipe products:


White stainless steel pipe is a popular name for stainless steel pipe in North China (especially in Northeast China). There are many kinds of stainless steel white steel pipe materials three hundred and four 304L three hundred and twenty-one three hundred and sixteen 316L 310S stainless steel pipe Etc.


    White stainless steel pipe It is a kind of high alloy steel which can resist corrosion in air or chemical corrosive medium, In order to maintain the inherent corrosion resistance of stainless steel, the 17% Above chromium, 8% Above. From the metallographic point of view, because the stainless steel contains chromium, a very thin chromium film is formed on the surface, which is separated from the oxygen invading into the steel and plays a role of corrosion resistance.


three hundred and four White stainless steel pipe has good intergranular corrosion resistance, excellent corrosion performance, cold working and stamping performance, which can be used as heat-resistant stainless steel. At the same time, the steel in the -180 Its mechanical properties are still good at ℃. In the solution state, the plasticity, toughness and cold workability of the steel are good; It has good corrosion resistance in oxidizing acid, atmosphere and water. The main features of white steel pipe are as follows: Corrosion resistance, high temperature resistance, low temperature resistance, tensile strength, low temperature impact, flattening, flaring, no cracking when bending So, three hundred and four The production and usage of white steel pipe is the largest and the most widely used steel grade.


The stainless steel white steel seamless pipe produced by Zhejiang Yihong is mainly used for fluid transportation and mechanical structure. It includes petrochemical industry, hydropower, thermal power, nuclear power, chemical fertilizer, boiler, ship, environmental protection, aviation, papermaking, food and medical fields.

The features of white stainless steel pipe in common use are as follows:

All stainless white steel pipes have the characteristics of corrosion resistance, high temperature resistance and no rust However, they have distinct characteristics and functions


three hundred and four White steel pipe: common corrosion resistance and high temperature resistant stainless steel seamless pipe, three hundred and four It has good intergranular corrosion resistance, excellent corrosion resistance, cold working and stamping properties, and can be used as heat-resistant stainless steel. At the same time, the steel in the -180 Its mechanical properties are still good at ℃. In the solution state, the plasticity, toughness and cold workability of the steel are good; It has good corrosion resistance in oxidizing acid, atmosphere and water.

     three hundred and four L White steel pipe It's low carbon three hundred and four Variants of stainless steel, It is used in the occasion where welding is needed The lower carbon content makes the carbides precipitated in the heat affected zone near the weld to a minimum, and the precipitation of carbides may cause intergranular corrosion (welding corrosion) of stainless steel in some environments.


  316/316L White steel The corrosion resistance of the pipe is better than that of the pipe three hundred and four White steel Tube It has good corrosion resistance in the production of pulp and paper. Due to the addition of Mo , corrosion resistance, especially Excellent pitting resistance High temperature strength is also good; Excellent work hardening ( Weak magnetism after processing ) The solution state is non-magnetic. There are also Good resistance to chloride attack, so it is usually used for marine environment Or coastal construction projects


  three hundred and twenty-one White steel pipe is pipe Ni-Cr-Ti Type a austenitic stainless steel, its properties and three hundred and four It is very similar, but because of the addition of titanium, it has Better grain boundary corrosion resistance and high temperature strength Due to the addition of titanium, the formation of chromium carbide is effectively controlled. three hundred and twenty-one Stainless steel has excellent high temperature stress rupture (Stress Rupture) Properties and creep resistance at high temperature (Creep Resistance) The stress mechanical properties are better than three hundred and four White steel pipe. three hundred and twenty-one White steel pipe Ti As a stabilizing element , But it is also a heat-resistant steel , Compared with high temperature 316L Much better. It has good wear resistance in organic and inorganic acids with different concentrations and temperatures, especially in oxidizing media , It is used to make lining and pipeline of wear-resistant acid container and wear-resistant equipment. It has certain high temperature resistance seven hundred It is often used in power plants. It is used in the field open-air machines of chemical, coal and petroleum industries with high requirements of grain boundary corrosion resistance, heat-resistant parts of building materials and parts with difficult heat treatment.


  310S White steel pipe : The most widely used anti-oxidation, corrosion resistance, high-temperature stainless steel pipe. Common use: furnace material, automobile purification device material. 310S Stainless steel white steel pipe is austenitic chromium nickel stainless steel, with excellent high temperature oxidation resistance, acid and alkali resistance, corrosion resistance, because of the high content of chromium (Cr) And nickel (Ni) So that it has much better creep strength, can work continuously at high temperature, has good high temperature resistance, and the temperature exceeds eight hundred The allowable stress began to decrease continuously, Maximum service temperature one thousand and two hundred C, continuous service temperature one thousand one hundred and fifty High temperature resistant steel pipe is specially used in the manufacture of electric furnace tubes. After increasing carbon content in austenitic stainless steel, its strength is improved due to its solid solution strengthening effect. The chemical composition of austenitic stainless steel is based on chromium and nickel, and molybdenum, tungsten, niobium and titanium are added. Because its structure is face centered cubic structure, it has high strength and creep strength at high temperature.
