Abstract

On at least the edge portion () of the lip portion () of a T-die (), a cladding layer () is provided. The cladding layer is formed by laser build-up welding to a base material with a powder of a corrosion resistant and wear resistant alloy comprising a nickel-based alloy or a cobalt-based alloy. The cladding layer has a metallographic structure in which metal borides are dispersed in a binder phase. The lip portion has high quality and has high durability. The manufacturing costs of the T-die can also be kept relatively low.
