Our company has established strategic cooperative partnerships with many large-scale domestic and overseas iron and steel enterprises; the H13 mandrel semi-finished products are jointly produced, while the finished products are heat-treated (quenched and tempered) by our company using heat treatment furnaces. As per customer’s requirements, a high-performance material welding layer can be added to the surface of the H13 mandrel, which can extend the service life of the mandrel and thus greatly save the rolling cost.
