X2CrNi12 CK201 RDSO Spec Coils are ferritic stainless steel coils manufactured according to RDSO specifications, primarily for Indian Railways and infrastructure projects. Their efficiency depends on a chromium-rich composition that forms a protective oxide layer upon air exposure. This protects structural integrity and ensures dimensional stability while offering balanced corrosion resistance and exceptional flexibility for rail coach and industrial components.
Each chemical element plays a functional role in ensuring the longevity and structural safety of RDSO grade steel.
