Product Overview
15CrMo, A387 Gr12 CL1/CL2 and 13CrMo4-5 (1.7335) belong to Cr-Mo alloy steel coil, widely used for high temperature pressure parts. Cr and Mo alloy elements greatly improve high temperature strength, anti-oxidation and creep resistance.
These alloy steel coils are normally normalized + tempered heat treated. Suitable for boilers, steam pipelines, heat exchangers, petroleum & chemical high-temperature reactors. We can supply hot rolled alloy steel coil with customized width & thickness. MTC 3.1/3.2 certification can be offered. Each batch will be tested for chemical composition and mechanical properties before shipment.
