What are the specific application ranges of super ferritic stainless steel?

 　　Ferritic stainless steel has been widely used in kitchen equipment, household appliances, building decoration, automobiles, environmental protection, municipal construction, and almost in various fields closely related to people's lives. In applications such as automobiles and kitchen equipment, its production and consumption still exceed that of chromium nickel austenitic stainless steel.

　　With the development of modern ferritic stainless steel, its weldability and corrosion resistance have been greatly improved compared to ordinary ferritic products, thus expanding its application fields. Especially in the production of products such as washing machine barrels, water heater liners, and automotive exhaust pipes, modern ferritic stainless steel can only be used.

　　400 series ferritic stainless steel refers to stainless steel with a chromium content between 11% and 30%. The basic structure of the steel at high temperature and room temperature is a body centered cubic crystal structure, and it is mainly ferrite in use. Ferritic stainless steel has the following characteristics and advantages: it does not contain precious metal nickel, has low cost, and is called economic stainless steel; It has broad application prospects and can be used in household appliances, automobiles, kitchen utensils, and decoration industries; Excellent stress corrosion resistance; Work hardening tendency is small, easy to cold heading and cutting; High thermal conductivity (1.5 times that of austenitic steel), making it very suitable for heat exchange purposes; The coefficient of linear expansion is small (60% of that of austenitic steel), suitable for use under thermal cycling conditions; Excellent magnetic conductivity.

Japanese Standard (1)

 　　In the grades of Japanese steel (JIS series), ordinary structural steel mainly consists of three parts to represent the material. 　　For example, S (Steel) represents steel, F (Ferrim) represents iron; The second part represents different shapes, types, and uses, such as P (Plate) for plates, T (Tube) for tubes, and K (Kogu) for tools; The third part represents the characteristic number, which is generally the tensile strength. For example, SS400 represents Steel, the second S represents Structure, 400 represents the lower limit tensile strength of 400MPa, and the overall represents ordinary structural steel with a tensile strength of 400MPa.

National Standard Properties of 304 Stainless Steel Plate

　　 304 stainless steel plate tensile strength (Mpa) 520 　　Yield strength of 304 stainless steel plate (Mpa) 205-210 　　Elongation rate of 304 stainless steel plate (%) 40% 　　304 stainless steel plate hardness HB187 HRB90 HV200 　　The density of 304 stainless steel is 7.93 g/cm3. Austenitic stainless steel generally uses this value. The chromium content (%) of 304 is 17.00 to 19.00, and the nickel content (%) is 8.00 to 10.00304, which is equivalent to 0Cr19Ni9 (0Cr18Ni9) stainless steel in China 　　304 stainless steel is a versatile stainless steel material with stronger rust resistance than the 200 series stainless steel material. It also has good resistance to high temperatures. 　　304 stainless steel has excellent rust resistance and good intergranular corrosion resistance. 　　For oxidizing acids, it was found in experiments that 304 stainless steel has strong corrosion resistance in nitric acid below boiling temperature with a concentration of ≤ 65%. It also has good cor...

Similarities and Differences in Performance between N08367 and N08926

 　　Today, let's talk about the similarities between the two. UNS N08367 and 1.4529 (N08926) materials are both super austenitic stainless steel. High Cr, high Mo, high corrosion resistance, and excellent corrosion resistance in harsh environments such as high-temperature seawater or smoke exhaust desulfurization devices. Under certain conditions, it has corrosion resistance comparable to Hastelloy and pure titanium, making it a cost-effective stainless steel. 　　If the performance is similar, the components must be very similar. 　　I'll show you the ingredient list and you'll know. 　　Except for the Cu element, which has a smaller intersection (0.5-0.75%), all other elements have a larger space, which means that other components can be completely identical. 　　So the two are basically the same and can to some extent replace each other. 　　The commonly used pitting resistance index (PRE) for stainless steel expresses the degree of corrosion resistance. 　　The calcul...
