11 Years Factory C45 Round Bar | AISI 1045 | DIN 1.1191 | JIS S45C Factory in New Orleans
Steel C45 Round Bar is an unalloyed medium carbon steel, which is also a general carbon engineering steel. C45 is a medium strength steel with good machinability and excellent tensile properties. C45 round steel is 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. It does not however respond satisfactorily to nitriding due to a lack of suita...

5. Forging of Carbon Steel C45 Round Bar
Hot forming temperature: 850-1200oC.
heat to 750 oC – 800 oC, then continue heating to 1100 oC – 1200 oC
maximum, hold until temperature is uniform throughout the section and
commence forging immediately. Forging is not workable below 850 oC.
Finished forgings could be air cooled.

8. Application of DIN Carbon Steel C45 Round Bar
C45 round bar steel material and steel plate C45, flats are widely used
in all industry for uses which require more strength and wear
resistance than the low carbon mild steel.
subsequently tempered steel for C45 steel grade round bar, steel plate,
flat and square is used for axles, bolts, forged connecting rods,
crankshafts, torsion bars, light gears, guide rods, screws, forgings,
wheel tyres, shafts, sickles, axes, knives, wood working drills,

Unless you know this, you’ll pull your hair out trying to hold tight tolerances on CRS. A must for machinists AND designers.
Mild steel is the common term for low carbon steel. Gas metal arc welding of mild steel is the most common form of welding.
In order to achieve a good weld:
-Make sure your work return lead has a clean surface and is secured firmly
-Make sure all plates are clean from rust, oil and grease
-Make sure there are no kinks in your hose for smooth wire transition
Parameter settings will vary depending on your application. Today, we’re welding 5mm thick carbon steel plate with an Alpha Q330 MIG machine, 1.2mm wire and ARGOSHIELD Light shielding gas which is an argon, oxygen and carbon dioxide mixture.
- Use a forehand welding technique at a 10 to 15 degree travel angle
- Keep electrode extension as short as possible and torch to work distance constant
- Ensure that your components are cleaned post weld before being put into service.
Remember that there is no universal set up when it comes to welding mild steel. Each machine may need to be specifically tuned by the operator based on the application and material being welded, the shielding gas mixture and wire being used, and any other unique requirements. Variations of heat input can be controlled by the voltage settings of the machine.
