Differences between 201 and 304 stainless steel plates

 　　1. Specification: Commonly used stainless steel plates are divided into two types: 201 and 304. In fact, the components are different. 304 has better quality, but the price is expensive. 201 has some differences. 304 is an imported stainless steel plate, and 201 is a domestic stainless steel plate.

　　2. 17CR-4.5Ni6Mn-N composed of 201 is nickel steel, which is a substitute for 301 steel. Magnetic materials can be used in railway vehicles after cold processing.

　　3. The 18CR-9Ni304 composed of 304 is the most widely used stainless steel and heat-resistant steel. Used in food production equipment, Sidon chemical equipment, nuclear energy, etc.

　　4. 201 has a high manganese content, a dark and bright surface, high manganese content, and is not easy to rust. 304 contains a lot of chromium, making the surface appear dull and non rusting. Compare the two. Most importantly, its corrosion resistance varies. 201 has poor corrosion resistance and is much cheaper in price. Meanwhile, due to the low nickel content and lower price of 201 compared to 304, its corrosion resistance cannot reach 304.

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...
