Stainless Steel Round Bar

Bright Bar

Bright bars are steel bars which are geometrically in precise shape and have tolerance which is tight dimensional. Its surface finish is smooth and shiny, which appears to be bright. Bright bar has good machining properties and are suitable for welding applications & can be case hardened also. Used in many engineering applications that requires less stress and mostly suitable for studs, bolts, shafts, threaded bars, spindles, axles and machinery parts.

Bright steel bar is a carbon steel alloy which has 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 & mechanical properties & improved dimensional tolerances & straightness.

Grades we Deal in:
Stainless Steel, Mild Steel, Alloy Steel & Carbon Steel.

Types of cold finished bars

Cold drawn bars are widely used in mass production of parts due to their excellent mechanical and dimensional properties, with machining characteristics in excess of the hot rolled bar condition. Round, hexagonal and square bars can be produced by cold drawing.

Turned and polished round bars have similar mechanical properties to those of equivalent hot rolled bar, but exhibit a smooth, bright surface finish and improved dimensional accuracy. They are widely used where a surface free of decarburisation is required, for example in induction hardening and when the surface must be free from surface defects, such as for use in cold forming.

Cold drawn and precision ground or turned and precision ground round bars, where very close dimensional tolerances and finishes are required, e.g. plating.

Cold rolled sizes up to 100mm wide and 7mm thick inclusive are produced by cold rolling to produce flat and some special shape sections to suitable tolerances and surface finishes.

Round Bar is a long, cylindrical metal bar stock that has many industrial and commercial applications. The most common application is shafts.
Standard diameters range from 1/4″ all the way up to 24″.
Other sizes may be available. Round Bar is available in many metal types including Hot-Rolled Steel, Cold-Rolled Steel, Peeled, Annelead, Ground Bar, Bright Bar, Black Bar in different grade such as Aluminum Bar, Stainless Steel Bar, Alloy Steel Bar, Carbon Steel Bar, Mild Steel Bar, Duplex Bar, Super Duplex Bar,  Monel Bar, Titanium Bar, Heat Treated Bar, Inconel Bar and more

Stainless steel grade 440A is a high carbon martensitic stainless steel that possesses good strength, moderate corrosion resistance, and excellent hardness and wear resistance. stainless steel grade 440A can be easily machined in the annealed condition. Carbide or ceramic tooling is recommended for performing machining. Chip breakers enable easy handling of tough stringy chips.

Equivalent materials to grade 440A stainless steel are given below.

AISI 440A             AMS 5631            AMS 5632            ASTM A276         ASTM A314

303 is a free machining chromium-nickel austenitic stainless steel with good strength and good corrosion resistance, as supplied in the annealed condition with a typical brinell hardness of 190.

Characterised by excellent machinablity and non galling properties due to its higher sulphur content, which has the effect of lowering slightly its corrosion resistance. It is however, fairly resistant to general atmospheric corrosion, general foodstuffs, sterilizing solutions, dyestuffs, most organic chemicals, plus some inorganic chemicals. But has very limited resistance to acids.

303 cannot be hardened by thermal treatment, but strength and hardness can be increased substantially by cold working, with susequent reduction in ductility.

It is used primarily for production runs involving extensive machining, or complex parts requiring excellent machinability.

Applications

Automatic screw machines

Conveyor systems

Architectural Components,

Food Processing Equipment,

 Dairy Equipment,

Dying Industry,

Hardware and Kitchenware manufacturing and allied industries.

Commonly used to manufacture Bolts and Nuts, Bushes, Gears, Shafts, Valve Bodies and Fittings etc.
