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.

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...

How are seamless steel pipes made? What are the theoretical weight specifications of seamless steel pipes?

图片
 　　A steel pipe made of a whole piece of metal with no seams on the surface is called a seamless steel pipe . Seamless steel pipes have a hollow cross-section and are widely used as pipelines for conveying fluids, such as pipelines for conveying oil, natural gas, coal gas, water and certain solid materials. According to the cross-sectional shape, seamless steel pipes are divided into round and special-shaped ones. Special-shaped pipes have square, oval, triangle, hexagon, melon seed, star, winged pipes and many other complex shapes. The following is a complete table of theoretical weights of seamless steel pipes, seamless steel pipe sizes and allowable deviation tables. 　　How are seamless steel pipes made? 　　1. Main production process of hot-rolled seamless steel pipes (△ Main inspection process): 　　Pipe blank preparation and inspection△→Pipe blank heating→Pipe perforation→Pipe rolling→Steel pipe reheating→Sizing (reducing) diameter→Heat treatment△→Finished pipe strai...
