Bars

Merchant Bar products are comprised of Hot Rolled and Cold Finished Carbon types as well as a number of sub-categories of shapes.  Infra-Metals offers many different sizes, lengths and specifications for Merchant Bar.

Specifications

HOT ROLLED

Merchant Bar Quality – A group of commodity steel shapes that consist of rounds, squares, flats, strips, angles and channels, which fabricators, steel service centers and manufacturers cut, bend and shape into products.  Merchant products require more specialized processing than reinforcing bar.

M1020 – A low carbon, general purpose, merchant quality steel.  Suitable for forming and welding.

M1044 – Medium carbon bars that are used where greater strength is required. Due to higher carbon content this grade is easily heat treatable but does not weld easily.

ASTM – A588 – This specification covers high-strength low-alloy bars and is primarily intended for use in bridges and buildings where strength and corrosion resistance is a factor.

COLD FINISHED

Low Carbon -1018 – A low carbon steel with a medium manganese content.  Has good hardening properties, fair machinability and is excellent for cold bending and forming operations.  Readily brazed and welded.  Suitable for shafting and for applications that do not require the greater strength of high carbon and alloy steels.  Conforms to ASTM A-108 and AMS 5069.  (Not applicable to bars under 2-15/16 and sizes lighter than 29.34 lbs per foot).

Ground & Polished Shafting – Extreme size accuracy, straightness and concentricity to minimize wear in high speed applications.  Turned, ground and polished bars can be machined unsymmetrically, as in key-seating, with minimum distortion because cold drawing strains are not developed.  Drawn, ground & polished bars combine the strength advantages of cold drawn stock with extra accuracy and lustrous finish.  Conforms to ASTM A-108 and QQ-S-637.
