Chinese Factory Selling 304 Stainless Steel Material Splayed Blind Forging Process

              Figure 8 is a kind of pipe parts, mainly to facilitate maintenance, the specific shape you can paint the upper part of the "8" black to know. It's half blind and half iron. It is often used for pipeline flanges that need to change the process. The materials are mainly carbon steel, stainless steel, alloy, which can be selected according to the pressure level of the pipeline and the pipeline medium.

              The meaning of use is usually used in the pipeline with a large diameter, usually use one end of the flange to occupy the distance to keep the pipeline smooth, and change to the blind plate of the same thickness at the other end to cut the pipeline when necessary. Avoid forced expansion of the pipeline due to temporary replacement of other blind plates, which will affect the entire system.

               304 stainless steel is a common material in stainless steel, with a density of 7.93 g/cm³; The industry is also called 18/8 stainless steel, which means containing more than 18% chromium and more than 8% nickel; High temperature resistance 800℃, with good processing performance, high toughness characteristics, widely used in industrial and furniture decoration industry and food and medical industry. However, it should be noted that compared with ordinary 304 stainless steel, food-grade 304 stainless steel has a more stringent content index. For example, the international definition of 304 stainless steel is mainly chromium 18%-20% nickel 8%-10%, but food-grade 304 stainless steel is chromium 18% and nickel 8%, allowing a certain range of fluctuations, and limiting the content of various heavy metals. In other words, 304 stainless steel is not necessarily food-grade 304 stainless steel

Among the common marking methods on the market are 06Cr19Ni10 and SUS304, of which 06Cr19Ni10 generally indicates national standard production, 304 generally indicates ASTM standard production, and SUS304 indicates daily standard production.

304 is a versatile stainless steel, which is widely used in the production of equipment and parts requiring good comprehensive properties (corrosion resistance and formability). In order to maintain the inherent corrosion resistance of stainless steel, the steel must contain more than 18% chromium and more than 8% nickel content. 304 stainless steel is a grade of stainless steel produced according to ASTM standards in the United States

              304 Stainless steel is the most widely used chrome-nickel stainless steel, as a widely used steel, has good corrosion resistance, heat resistance, low temperature strength and mechanical properties; Stamping, bending and other hot processing good, no heat treatment hardening phenomenon (use temperature -196℃~800℃). Corrosion resistance in the atmosphere, if it is an industrial atmosphere or heavily polluted areas, it needs to be cleaned in time to avoid corrosion. Suitable for food processing, storage and transportation. It has good processability and weldability. Plate heat exchanger, bellows, household goods (1, 2 types of tableware, cabinets, indoor pipelines, water heaters, boilers, bathtub), auto parts (windshield wipers, mufflers, molding products), medical equipment, building materials, chemicals, food industry, agriculture, ship parts, etc. Among them, the content of 304 stainless steel is strictly controlled, which can also be called food-grade 304 stainless steel

Most of the use requirements are to maintain the original appearance of the building for a long time. When determining the type of stainless steel to be selected, the main consideration is the required aesthetic standards, the corrosiveness of the local atmosphere and the cleaning system to be used. However, other applications are increasingly simply seeking structural integrity or impermeability. For example, the roofs and side walls of industrial buildings. In these applications, the owner's construction cost may be more important than aesthetics, and the surface is not very clean. 304 stainless steel works quite well in dry indoor environments. However, in rural and urban areas, if you want to maintain its appearance outdoors, it needs to be cleaned frequently. In heavily polluted industrial areas and coastal areas, the surface will be very dirty and even rust.

However, to obtain the aesthetic effect in the outdoor environment, it is necessary to use nickel-containing stainless steel. Therefore, 304 stainless steel is widely used in curtain walls, side walls, roofs and other architectural purposes, but in the industrial or Marine atmosphere with serious erosion, it is best to use 316 stainless steel. Stainless steel doors, people have fully recognized the advantages of using stainless steel in structural applications. Several design guidelines include 304 and 316 stainless steel. Because "duplex" stainless steel 2205 has combined good atmospheric corrosion resistance with high tensile strength and elastic limit strength, this steel is also included in the European guidelines. In fact, stainless steel is manufactured in all standard metal shapes and sizes, and there are many special shapes. The most commonly used products are made of sheet and strip steel, and special products are also made of medium and thick plates, for example, the production of hot rolled structural steel and extruded structural steel. There are also round, oval, square, rectangular and hexagonal welded pipe or seamless steel pipe and other forms of products, including profiles, bars, wires and castings.
