Super Alloy Steel Pipe Precipitation Harding Alloy 41 Untuk Komponen Mesin
Alloy Steel Pipe Alloy 41 precipitation hardening Nickel-Base Superalloy
Alloy41 adalah Superalloy Nickel-Base yang mengeraskan precipitasi, dan memiliki kekuatan tarik dan merangkak yang lebih tinggi dan ketahanan oksidasi yang baik dalam kisaran suhu 650 ~ 950 °C.Karena paduan aluminium, titanium, kandungan molibdenum tinggi, bunga ingot lebih sulit, tetapi bahan setelah deformasi memiliki ductility yang baik,yang membuatnya lebih mudah terbentuk dingin atau dilas dalam keadaan annealedNamun, bagian yang dilas mudah rentan terhadap retakan dan penuaan saat diobati panas.dan cocok untuk pembuatan di bawah 870 °C dengan kekuatan tinggi dan di bawah 980 °C oksidasi suhu tinggi dari komponen mesin penerbangan dan aeroangkasa.
