Abstract
A seamless steel vessel, such as a tube having extreme ductility and softness in the hotformed state is made from the alloy described in the parent Specification by hot-forming at a temperature in excess of 1000 DEG C. but below the melting point of the alloy and then rapidly cooling. Before the vessel is rapidly cooled it may be annealed by heating at a temperature above 750 DEG C. but below the melting point of the alloy, e.g. between 850 and 950 DEG C. for a time between two minutes and two hours. The alloy may contain up to 2 per cent of molybdenum, up to 3 per cent of tungsten and aso small amounts not exceeding 2 per cent of manganese, silicon aluminium and zirconium.
