4J52 Expansion Alloy Corrosion Resistant Alloy Light Rod
KX 4J52 Corrosion Resistant Alloy Light Rod On Expansion Alloy
Product Description and Application
4J52 is something like Alloy 50
4J52 has excellent comprehensive properties in the temperature range from -253 ℃ to 700℃. The yield strength below 650℃ ranks the first among deformed superalloys, and has excellent performance, machining performance and welding performance. It can manufacture all kinds of parts with complex shapes, and has been widely used in aerospace, nuclear energy, petroleum industry and extrusion mold in the above temperature range.
