Stainless steel is marked with and , martensitic stainless steel is marked with and C, duplex (austenite ferrite), stainless steel, precipitation hardening stainless steel and high alloy with iron content less than % are usually named by patent name or trademark.Alloy elements. Chromium is the basic element for stainless steel to obtain corrosion resistance. When the chromium content in the steel reaches about %, which can prevent the further corrosion of the steel matrix. In addition to chromium common compoundIan,Stainless steel is mainly used in the exhaust system, accounting for more than % of the total consumption of automotive stainless steel, and % is ferritic stainless steel. The exhaust gas produced by the automobile engine is discharged from the intake pipe, front pipe, hose, converter and central pipe. The commonly used steel types of exhaust system areThin plate (.mm-mm), medium plate (mm-mm) thick plate (mm-mm) extra thick plate according to the production of hot-rolled steel plate, cold-rolled steel plate according to the surface characteristics, the outline of the manufacturing method of surface characteristics, silver white matte, hot rolled to the specified thicknessMegara, weldability and thermal strength. h stainless steel is used for large boiler superheater, reheater, steam pipeline and petrochemical heat exchanger pipe fittings.For cars with high safety and long service life, such frames can be recycled for secondary use. It can not only save costs, but also save resources. And the auto parts of some other parts are also made of stainless steel. Stainless steel has a great potential market in the whole automobile industry!After fine tuning the molten steel temperature in the argon blowing station, it is lifted to the Ladle Turntable for continuous casting.

In particular, wire drawing board or frosted board has better wear resistance than other surface texture states.However, some people will still communicate online or by telephone to ask whether our stainless steel pipe can be used as water pipe.For example, like , which is common in the market, the raw material difference of the three materials lies in more than yuan per ton.Variable cost, stainless steel pipe and ferritic stainless steel according to the matrix structure. Chromium content % ~ %. Its corrosion resistance, toughness and weldability increase with the increase of chromium content, and its chloride stress corrosion resistance is better than other kinds of stainless steel.It can be found that the finite element model can well predict the failure mode of stainless steel square pipe string after high temperature. In order to make the outer surface roughness of cold processed precision stainless steel pipe meet the product quality requirements, an intelligent polishing equipment for the outer surface of precision stainless steel pipe is developed. The equipment adopts selfThere is also a spectrometer detection method, which is a relatively simple and fast way.

In austenite and then rapidly cooled. For thin-walled parts, air cooling can be adopted, and water cooling is generally adopted.demand,Since the beginning of last year, foreign countries have frequently carried out & ldquo; Double reverse & rdquo; This has a great impact on China's stainless steel casting industry. Export is a large part of the development of China's stainless steel industry and occupies a huge market share in its industrial development,Objective to improve the existing connection mode of the braking system pipe system of railway freight cars, so as to obtain the forged joint with better mechanical properties. According to the connection mode of the original pipe system and the plastic forming characteristics of steel pipe,Ian403 high quality stainless steel plate, the method of multi-step upsetting and extrusion at the end of stainless steel pipe is put forwardThe product quality advantage of continuous casting billet of stainless steel pipe fittings is mainly reflected in the fact that the non grinding rate of the outer surface of the billet except the head and tail section has reached more than %, and the total surface grinding yield has reached %. In order to achieve this goal, it is necessary to refine the molten steel, achieve low oxygen and sulfur content, and do a good job in ladle andIan, the steel resistant to weak corrosion medium is often called stainless steel, while the steel resistant to chemical medium is called acid resistant steel. Due to the difference in chemical composition between the two the former is not necessarily resistant to chemical medium corrosion, while the latter is generally stainless. The corrosion resistance of stainless steel depends on the content in the steelIt will react with the atmosphere to repair itself, re form this passive film and continue its protective effect.There are ba surface, b surface, (white skin), D surface, (frosted), HL (wire drawing), K surface and other surfaces with good quality and brightness.
