QUALITY / MANUFACTURING PRACTICES of 1.5918 forged parts
Material furnished shall be commercially sound and free from external and internal defects that would make it
unsuitable for forging, machining or heat treating normally employed in processing. This includes seams,
laminations, cold shuts, incipient melting (""burning""), and excessive non-metallic inclusions. Surfaces shall be
free of high temperature scale."
Remnant as-case dendritic pattern or alloy segregation is undesirable in hot rolled or forged products. This
should not be found in critical stress areas due to reduced mechanical properties and can pose machinability
problems. Areas considered as critical may be indicated on the engineering drawing.
All material furnished must be fully killed. The material may be subsequently processed by vacuum degassing,
argon stirring, vacuum arc or electroslag remelting, controlled cooling, etc."
In cases not covered by specific standard practices, the product furnished shall be in accordance with
accepted trade practices.
