Introduction to the Properties of GH2136 (GH136) Precipitation Hardening Deformation High Temperature Alloy

 　　GH2136 (GH136) precipitation hardening deformation high-temperature alloy

　　GH2136 is a Fe Ni Cr based precipitation hardening deformation high-temperature alloy, used at temperatures below 700 ℃. This alloy is developed on the basis of GH2132 alloy, which reduces the manganese and silicon content and appropriately increases the titanium, boron, and carbon content. In long-term use, this alloy reduces the G phase σ The precipitation tendency of equal brittle phases improves the stability of the alloy's microstructure and properties during long-term use. The alloy has good comprehensive properties, stable microstructure after long-term use, good oxidation resistance, small linear expansion coefficient, and is easy to weld and form. The main products include bars and forgings.

　　Alloys have been used to produce turbine discs and other high-temperature components for aircraft engines operating at 650 ℃ -700 ℃.

　　After long-term aging at 600 ℃ -700 ℃ for 1000h-3000h, the γ‘ Gradually moving towards η Phase transformation and reduction of creep and endurance limits. Cellular form η The phase forms at around 800 ℃ and appears in the form of flakes or Weinsteinite at higher temperatures, reducing the impact toughness and plasticity of the alloy.

　　Heat treatment system

　　Hot rolled bars, forged bars, forgings: fixed at 980 ℃ for 1 hour, water cooled, aged at 720 ℃ for 16 hours, air cooled

　　Density: 8.03

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...
