Ooru Itoju fun A387 Chrom Moly Alloy Irin Awo

Chrome moly alloy irin awo labẹ ASTM A387 li ao pa irin, pẹlu thermally mu boya nipa annealing, normarlizing ati tempering. Tabi ni ọran ti o gba nipasẹ olura, itutu agbaiye lati iwọn otutu austenitizing nipasẹ fifun afẹfẹ tabi pipa omi, atẹle nipasẹ iwọn otutu, awọn iwọn otutu iwọn otutu yoo jẹ bi tabili ni isalẹ:

Ipele	Iwọn otutu, °F [°C]
