Cast Iron
, however, some analysis requirements may also be specified. Patternmaking is no longer a necessary step in manufacturing cast-iron parts. Many gray, ductile, and alloy-iron components can be machined directly from bar that is continuously cast to near-net shape. Not only does this "parts-without-patterns

Carbon Steel
of rimmed steels is practically free from carbon and is very ductile. For these reasons, rimmed steels are often specified for cold-forming applications. Rimmed steels are often available in grades with less than 0.25% C and 0.60% Mn. Segregation -- a nonuniform variation in internal characteristics

Refractory Metals
inert atmospheres; and by electron-beam welding in vacuum. The best welds are produced by inertia (friction) welding and electron-beam welding; welds produced by the other techniques are less ductile. Generally, arc-cast metal develops better welds than do powder-metallurgy products. Heavy sections

or stainless-steel 414 (free-machining grade). Both are supplied in the low 200BHN scale (Brinell hardness number), which usually means a special melt (and a special order) from the foundry. 200 BHN is considered medium-soft and suitable for machining. It is ductile and generates long stringers when

hot-forging lines and an expanded plant totaling about 200,000 ft2. Each line makes more than 10,000 PF connecting rods daily. Hoeganaes Corp. introduced five binder-treated powders. Three of them target high-performance P/M parts designed to replace malleable and ductile irons. The other two are said
