HOT ROLLED STEEL BARSTO MEET EVERY NEED
HOT ROLLED:
ASTM A36 – General purpose structural quality steel offering a36,000 psi minimum yield point. Easily welded and fabricated. Usedfor general repairs, tie rods, machinery frames, brackets, etc.
CSA G40.2144W – Steels may be categorized as the “garden variety” steel for general welded construction in Canada. They areusually produced to a semi-killed steel-making practice. The controlof carbon and manganese contents is such that normal good fieldwelding procedures will give satisfactory results. This is the recom-mended steel type for normal building construction where shop andfield welding is to be used. Although not recommended for low tem-perature service, these steels are widely used in compressionmembers of bridges and similar structures and other applicationswhere the possibility of brittle fracture is remote.
CUT & STRAIGHTENED ROD – A soft grade of steel, about 1008 to 1010 carbon, produced from coils of wire. By passingthrough the straightening rolls a bright finish is obtained similar tocold finished bars. Uses are where severe bending is necessary,i.e., frames for purses and handbags, or for appearance such as filing cabinet rods.
AISI 1018/1020 – General purpose machinery steel of the lowcarbon grade. Can be formed and welded. Uses are bolts orhammer forgings especially when case hardening is required.
AISI 1045 – Medium carbon machinery steel offering higherstrength than low carbon in the as rolled condition. Can also beheat treated or induction hardened. – Uses include gears, axles,shafts, bolts, etc.
