AISI 1045 Carbon steel flat steel hot rolled customized logo
It does not however respond satisfactorily to nitriding due to a
lack of suitable alloying elements. 1045 is used extensively by all
industry sectors for applications requiring more strength and wear
resistance than the low carbon mild steels can provide and the
higher strength of the low alloy high tensile steels is not
necessary, plus those applications requiring flame or induction
hardening. Flat steel refers to the steel 12-300mm wide, 3-60mm
thick, rectangular in section with a slightly blunt edge.Flat steel
can be finished steel, can also be used as blank for welded pipe
and thin slab for laminated sheet.Main use: flat steel as a forming
material can be used for making hoop iron, tools and mechanical
parts, used as structural parts of building frame, escalator.
Flat bar is usually a carbon steel alloy which has had the surface condition improved by drawing, peeling or grinding over the hot rolled finish supplied by the steel mill. Advantages achieved include improved machining, less wastage at component production stage, enhancement of physical and mechanical properties and improved dimensional tolerances and straightness.
1045 is a medium tensile low hardenability carbon steel generally
supplied in the black hot rolled or occasionally in the normalised
condition, with a typical tensile strength range 570 - 700 Mpa and
Brinell hardness range 170 - 210 in either condition.Characterised
by fairly good strength and impact properties, plus good
machinability and reasonable weldability in the hot rolled or
normalised condition.
1045 has a low through hardening capability with sections up to
around 60mm only generally recommended as suitable for through
hardening and tempering. It can however be successfully flame or
induction hardened in the as rolled or normalised condition
resulting in surface hardnesses of up to Rc 54 - Rc 60 depending
upon quenching medium employed, type of set up, section size etc.
Core strengths will remain as supplied.

Application:
Flat steel flat bar point to the the steel that the width is 12-300
mm, the thickness is 4-60mm m thick, and cross section is rectangle with the edge of a little
pure steel.
Main use: flat as timber can be used in the system of hoop iron
parts, tools and machinery.It also can be used as frame structure and escalator. Flat Bar is used for general fabrication, making structures and
frames. Mild Steel Flat Bar can be easily cut and drilled, and is
particularly suited to welding. Examples of its use include furniture making, machinery
manufacturing, shipbuilding, railway spare parts, iron towers, steel structures,
and boilers.
Cold drawn 1045 steel bar is a medium carbon steel grade with higher mechanical properties, fair weldability and limited formability. This grade is widely available and commonly stocked because of its excellent properties and cost. Eaton Steel Bar Company stocks several diameters of this grade to meet your demands quickly. All cold finished material is manufactured to meet ASTM A108 requirements. We also stock many sizes that are JDM QL-2 certified. Grade 1045 cold drawn steel bar provides greater dimensional control, improved straightness, and better surface condition to aid in machining. We commonly supply 1045 cold drawn steel bar to various industries like automotive, agriculture, ATV, and motorcycle.
Hot rolled 1045 steel bar is a medium carbon common steel grade with moderate weldability, higher strength, and impact properties for a variety of applications. 1045 steel is a common grade because of its cost and excellent properties. However, due to its lack of alloying content, this grade has limits on mechanical properties and options for heat treatments.
