Product Description
Mandrel bar
Seamless pipe manufacturing
Mandrel bar is the important parts in producing large diameter seamless pipe. In production the mandrel bar is under strong and complicate strength, compressing touching stress and high temperature cold-hot yield stress, so it strictly requires all the factors of steel, including chemical components, mechanical properties, no-metallic inclusion, grain size, microstructure, ultrasonic test, size precision, surface finish. The main material for the mandrel bar is H13(4Cr5MoSiV1)
Chemical component
AISI H13(4Cr5MoSiV1)
