scope:

This specification covers requirements for general applications of carbon and alloy cold finished steel bars. Whenever applicable the specification should be used in conjunction with MPAPS A-0, Part II, Navistar System of Steel Classification. Unless otherwise specified, the appropriate ASTM Specifications shall apply to this specification.

Requirements for cold finished steel bars not included in this specification are in the following Corporate Engineering Materials Specifications:

Wrought Corrosion and Heat Resisting Steel MPAPS A-37

HSLA Grade 50 or similar Materials MPAPS A-43

Restricted Chemical Substances

All product supplied to the requirements of this specification must comply with the requirements of the MPAPS B-50 specification.

APPLICATION

Cold finished bars are free from scale, have closer dimensional tolerances, better machinability, and offer improved mechanical properties. They are also more expensive than hot rolled bar products.
