1, Introduction to Grade 660:
Grade 660 is a precipitation hardening alloy with high mechanical properties. This alloy maintains good strength and yang resistance at temperatures up to approximately 1300 ° F (700 ºC). The high strength and excellent manufacturing characteristics of this alloy make it suitable for various components of aircraft and industrial gas turbines. Applications include blades, blades, shafts, tail cones, afterburner, springs, and fasteners. This stainless steel alloy is also used in automotive applications.
2, Grade 660 applications and features:
Characteristics and Application of Grade 660: Grade 660 has superior high-temperature strength to austenitic stainless steel below 700 ºC, and belongs to precipitation hardening heat-resistant stainless steel. Compared to 304, it has a higher Ni content and is supplemented with hardening elements such as Ti and Al. Therefore, through age hardening treatment, there will be γ' The precipitation of phase (fcc_Ni3 (Al, Ti)) will significantly improve the high-temperature strength.
Grade660 high-temperature alloy is a high-quality corrosion-resistant and high-temperature resistant material widely used in fields such as aerospace, marine engineering, and chemical engineering. It has characteristics such as high strength, heat resistance, corrosion resistance, and oxidation resistance, and can maintain stable performance in harsh environments such as high temperature, high pressure, acid and alkali. The application in industries such as automobiles, ships, and electricity is also becoming increasingly widespread. I believe that with the continuous progress of technology, the application of Grade660 high-temperature alloy in more fields will be further expanded and deepened.
GH660 alloy is a high-temperature alloy, whose chemical composition mainly includes nickel, chromium, molybdenum, iron, and other trace elements. Among them, nickel is the main component of GH660 alloy, and its content is usually above 50%. The content of chromium is usually between 15-25%, and the content of molybdenum is usually between 5-10%.
In addition, GH660 alloy also contains a small amount of elements such as copper, cobalt, titanium, zirconium, and aluminum. The addition of these elements can improve the corrosion resistance, heat resistance, and mechanical properties of GH660 alloy, enabling it to perform well in harsh environments such as high temperature, high pressure, and strong corrosion. GH660 alloy is widely used in aviation, aerospace, energy, chemical and other fields, and is an important high-performance material.
