304 stainless steel products
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 800 degrees, with good processing performance, high toughness characteristics, widely used in industrial and furniture decoration industry and food and medical industries.
The common marking methods in the market are 06Cr19Ni10, SUS304, of which 06Cr19Ni10 generally represents the national standard production, 304 generally represents the ASTM standard production, and SUS 304 represents the daily standard production.
304 is a versatile stainless steel that is widely used to make equipment and parts that require good overall performance (corrosion resistance and formability). In order to maintain the inherent corrosion resistance of stainless steel, steel must contain more than 18% of chromium, more than 8% of the nickel content. 304 stainless steel is a grade of stainless steel produced according to American ASTM standards. 304 is a versatile stainless steel that is widely used to make equipment and parts that require good overall performance (corrosion resistance and formability).
Chinese name 304 stainless steel Foreign name 304 stainless steel products Meaning Universal stainless steel Features Corrosion resistance and formability Phenomenon Work hardening phenomenon
301 stainless steel shows a significant work hardening phenomenon during deformation and is used in various applications requiring higher strength.
302 stainless steel is essentially a variant of 304 stainless steel with higher carbon content, which can be obtained by cold rolling.
302B is a kind of stainless steel with high silicon content. It has high resistance to high temperature oxidation.
303 and 303Se are free-cutting stainless steels that contain sulfur and selenium, respectively, and are used in applications where high lightness and high lightness are primarily required. 303Se stainless steel is also used to make parts that require hot boring because the stainless steel has good hot workability under these conditions.
304L is a variant of 304 stainless steel with a low carbon content and is used where welding is required. The lower carbon content minimizes the precipitation of carbides in the heat-affected zone near the weld, and the precipitation of carbides may result in intergranular corrosion of the stainless steel in some environments (weld erosion).
304N is a nitrogen-containing stainless steel that is added to improve the strength of the steel.
305 and 384 stainless steels contain high nickel and have a low work-hardening rate. They are suitable for a wide range of applications requiring high cold formability.
308 stainless steel is used to make the electrode.
309, 310, 314, and 330 Stainless steels have higher nickel and chromium contents to improve the oxidation resistance and creep strength of steel at high temperatures. The 30S5 and 310S are variants of the 309 and 310 stainless steels. The only difference is that the carbon content is low, in order to minimize the precipitation of carbides near the weld. 330 stainless steel has a particularly high resistance to carburization and thermal shock resistance.
Type 316 and 317 stainless steels contain aluminum, which greatly outperforms 304 stainless steels in marine and chemical industry environments. Among them, Type 316 stainless steel consists of variants including low-carbon stainless steel 316L, nitrogen-containing high-strength stainless steel 316N, and high sulfur-rich free-cutting stainless steel 316F.
321, 347, and 348 are stainless steels stabilized with titanium, niobium, tantalum, and niobium, respectively, and are suitable for use as welded components at high temperatures. 348 is a stainless steel suitable for the nuclear power industry. It has certain restrictions on the amount of helium and drill.
