HastelloyC-276 Material Introduction

　　HastellyC-276 (UNS N10276/7,. 2.4819) alloy exhibits excellent corrosion resistance to most corrosive media in both oxidation and reduction states. Excellent resistance to point corrosion, barrier corrosion, and stress corrosion cracking. Alloys are suitable for various chemical process industries containing oxidizing and reducing media. The high content of key and chromium makes the alloy resistant to chloride ion corrosion, and tungsten further improves its corrosion resistance. Hastellor-276 is one of the few materials that can withstand the corrosion of humid chlorine gas, hypochlorite, and complex solutions of dioxide. This alloy has significant corrosion resistance to high concentration complex salt solutions (such as iron chloride and copper chloride).

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.

　　 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

图片
 　　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...
