What standard is MA758?

MA758 is a nickel-based high-temperature alloy material standard classified as a high-performance superalloy.

Inconel MA758 is a special high-temperature nickel alloy that is a type of superalloy and is known for its excellent mechanical strength, creep resistance, good surface stability, and excellent corrosion and oxidation resistance. This alloy maintains good performance in high-temperature environments and is therefore widely used in demanding high-temperature fields. Here are some details about MA758 alloy:

Chemical composition: MA758 alloy contains elements such as chromium (Cr), nickel (Ni), aluminum (Al), titanium (Ti), iron (Fe) and yttrium trioxide (Y2O3). These elements together give the alloy its unique performance.
Physical properties: The alloy has a high density and high melting point, which indicates its ability to maintain a stable physical state at extreme temperatures.
Mechanical properties: MA758 alloy has high yield strength and tensile strength at room temperature, which makes it excellent in mechanical applications. For example, its rod yield strength is 560 MPa and tensile strength is 949 MPa; plate yield strength is 680 MPa and tensile strength is 1030 MPa.
Characteristics: MA758 alloy has good oxidation resistance and glass liquid resistance, making it suitable for applications in contact with high-temperature metals and alloys, such as aerospace engine blades, iron furnace components, etc.
Application areas: Due to its excellent properties, MA758 alloy is used in parts during heat treatment, diesel engine fuel atomization applications, and other areas with strict requirements for high temperature performance.
