Introduction of 304 stainless steel
304 stainless steel is a common material in stainless steel with a density of 7.93 g/cm3, also known as 18/8 stainless steel in the industry. High temperature resistance of 800 degrees, has the characteristics of good processing performance and high toughness, and is widely used in industrial and furniture decoration industries and food and medical industries.
The common marking methods in the market include 06Cr19Ni10 and SUS304, of which 06Cr19Ni10 generally means national standard production, 304 generally means ASTM standard production, and SUS 304 means Japanese standard production.
304 is a general-purpose stainless steel, generally made into coils or plates, which is widely used to make equipment and parts that require good comprehensive performance (corrosion resistance and formability). To maintain the inherent corrosion resistance of stainless steel, the steel must contain more than 18% chromium and more than 8% nickel. 304 stainless steel is a grade of stainless steel produced according to the American ASTM standard.
Application of 304 stainless steel
304 stainless steel coil has beautiful surface and diversified use possibilities; good corrosion resistance; longer durability than ordinary steel; good corrosion resistance; high temperature oxidation resistance and high strength, so it can resist fire; good plasticity and good welding performance. It has excellent corrosion resistance of stainless steel, and 304 stainless steel coil also has good resistance to intergranular corrosion and good processing performance. Due to the above advantages, 304 stainless steel coil is widely used to make equipment and parts that require good comprehensive performance (corrosion resistance and formability), such as food production equipment, tableware, Xitong chemical equipment, nuclear energy, exterior materials, construction Materials, auto parts (semi-trailer tank body), medical equipment, fiber industry and ship parts, etc.
304 stainless steel is the most widely used chromium-nickel stainless steel. As a widely used steel, 304 stainless steel has good corrosion resistance, heat resistance, low temperature strength and mechanical properties. Good hot workability such as stamping and bending, no heat treatment hardening phenomenon (use temperature -196°C ~ 800°C). Corrosion resistance in the atmosphere, if it is an industrial atmosphere or heavily polluted area, 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 exchangers, bellows, household items (1 and 2 tableware, cabinets, indoor pipelines, water heaters, boilers, bathtubs), auto parts (windshield wipers, mufflers, molded products), medical appliances, building materials, chemicals, food industry , agriculture, ship parts, etc. 304 stainless steel is an internationally recognized food-grade stainless steel.
Most of the usage requirements are to maintain the original appearance of the building for a long time. When determining the type of stainless steel to choose, the main considerations are the required aesthetic standards, the corrosiveness of the local atmosphere, and the cleaning system to be used. However, more and more of its prospective applications simply seek structural integrity or water impermeability. For example, the roof 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 reasonably well in dry indoor environments. However, to maintain its appearance outdoors in rural and urban areas, frequent cleaning is required. In heavily polluted industrial areas and coastal areas, the surface can be very dirty and even rust. However, for an aesthetic effect in an outdoor environment, nickel-containing stainless steel is required. Therefore, 304 stainless steel is widely used in curtain walls, side walls, roofs and other architectural purposes, but in severe corrosive industrial or marine atmospheres, 316 stainless steel is best used. Stainless steel sliding doors, people have fully recognized
Recognized the advantages of using stainless steel in structural applications. 304 and 316 stainless steels are included in several design guidelines. Because the "duplex" stainless steel 2205 combines good atmospheric corrosion resistance with high tensile and elastic strengths, this steel is also included in European guidelines. Product Shapes In fact, stainless steel is manufactured in full standard metal shapes and sizes, and many special shapes are available. The most commonly used products are made from sheet and strip, but special products are also produced from plate, such as raw shovel hot-rolled structural steel and extruded structural steel. There are also round, oval, shaped, rectangular and hexagonal welded or seamless steel pipes and other forms of products, including profiles, bars, wires and castings. The price of 304 stainless steel is relatively moderate and cost-effective. So it is widely used in our production and life.
Width and thickness of 304 stainless steel
Commonly used 304 stainless steel coil widths are generally 1 meter, 1.22 meters, 1.5 meters, and 1.8 meters. The thickness is generally 0.3-3.0.
Types of 304 Stainless Steel
304 stainless steel coils are divided into austenitic stainless steel cold-rolled coils and stainless steel hot-rolled coils.
304 stainless steel coil price
Different types of 304 stainless steel coil have different prices. Their price is also related to width and thickness. The thinner the thickness, the more expensive the price. In general, the price range of 304 stainless steel coil is between $1,000.00-$1,875.00 / ton.
