Abstract

The powder for making the sintered object consists of a base material and an additive material, the base material amounting to at least 90% by weight of the finished powder. The base material consists of an austenitic steel with at least 12% of chromium, 6% of nickel, 1% of molybdenum, at most 1% of silicon and at most 0.05% of carbon. The additive material contains at least 55% of iron, 10 to 20% of phosphorus and 10 to 20% of molybdenum. This powder can be sintered under a pressing force of 500 to 800 MPa to give a pressed part and subsequently between 1,100 DEG C and 1,200 DEG C to give a shaped object which is corrosion-resistant, weldable and dense and can be inexpensively produced in a continuous process.
