Process for producing a clad moulded body

In a process for producing a clad, in particular roll-bonding clad, moulded body consisting of a base material and at least one high- alloy, rustproof cladding material, the cladding material consists of 0.001 to 0.1% by weight of C, 0.001 to 2.0% by weight of Si, 0.01 to 5.0% by weight of Mn, 0.5 t...

Zusammenfassung:	In a process for producing a clad, in particular roll-bonding clad, moulded body consisting of a base material and at least one high- alloy, rustproof cladding material, the cladding material consists of 0.001 to 0.1% by weight of C, 0.001 to 2.0% by weight of Si, 0.01 to 5.0% by weight of Mn, 0.5 to 40.0% by weight of Cr, 35.0 to 80.0% by weight of Ni, 7.0 to 30.0% by weight of Mo, up to 5.0% by weight of Cu, up to 1.0% by weight of Ti, up to 1.0% by weight of Nb, up to 0.04% by weight of P, up to 5.0% by weight of W, up to 0.025% by weight of S, and the remainder of iron and impurities due to melting. After the cladding, the materials are heated to a temperature of between 1,000 and 1,150 DEG C, then quenched to a temperature of between 700 and 450 DEG C, preferably between 620 and 550 DEG C, at a cooling rate of between 10 DEG C/s and 1 DEG C/s and subsequently cooled using still air at a cooling rate of between 15 DEG C/min and 5 DEG C/min.
