Carbon Steel Square Bars Supply to Maharashtra

We have large quantities of standard carbon grades, in a variety of section sizes, on stock as Carbon Steel Square Bars Suppliers in Maharashtra, and they can be machined or fabricated immediately, without going through the production schedule of a mill. Purchasing out of stock instead of out of a mill implies that the size you need is issued, but not bound to a complete heat run on a few standard sizes. Both black, and bright square bars are gripped, thus the condition of the surface can be correlated with a section passing straight to fabrication or to a machine shop.

Industries Using Carbon Steel Square Bars

The carbon steel square bar is defined where a component requires a flat-sided section to be machined, to be keyed or used structurally, over a wide range of industries:

• General engineering - machined blocks, keys, spacers, tool bodies.
• Auto parts - machined fittings, parts of a structure, brackets.
• Construction and fabrication - grilles, gates, structural framing.
• Equipment Agricultural Equipment - frame members, mounting brackets.
• Tool and furniture manufacturing - jig blocks, clamping bars, locating keys.
• Furniture and fittings- frames, legs, structural hardware.

Trusted Carbon Steel Square Bars Stockists in Maharashtra

Since we are an established Carbon Steel Square Bars Stockist in Maharashtra, we stock the available parts in the sizes of sections that fabricators and machine shops actually order, and part-quantities can be discharged without a wait until we meet mill tonnage requirements. Stocking in Mumbai, Pune, Nagpur, Nashik, Aurangabad, Kolhapur, Solapur, Thane, Navi Mumbai also implies continuity of heat through a production run, and the mechanical properties of a batch of components machined or formed of the same section can be the same.

Machining Allowance and Surface Condition

The most important decision on square bars is the amount of stock removal your process requires because either ordering an inappropriate surface condition wastes material or results in leaving surface defects behind. Black square bar has scale and surface decarburisation on all four faces, and therefore requires generous allowance to enable any face to be machined true. Bright square bar is delivered peeled or milled to near finished size on all sides, eliminating scale and decarburised layer, resulting in less material going to waste in facing cuts and a more uniform corner to corner squareness.

Selecting the Appropriate Grade

The choice of grade to use in square bar is reduced to what the section will actually become after machining or fabrication, which is free machining, overall strength, wear resistance or structural weldability each indicating a different grade:

• EN1A / EN1A Lead - free-cutting, low carbon alloys with sulphur added (EN1A Lead) to machine fast and clean; used in high volume parts that are turned and/or milled where the cycle time is more important than strength.
• EN3B - soft, low carbon, and weldable, structural frames, brackets and light stress structural fabrication.
• EN8 / C45 medium carbon, a working balance of strength and machinability: used in general engineering, machine bases and mounting components.
• EN8D - similar to EN8 with added sulphur to enhance machinability; used where large quantities of machining take precedence over a slight trade-off in weldability.
• EN9 - above carbon, stronger and more resistant to wear, however, machines wear more tools and are difficult to weld; used in load-bearing or wear-sensitive components.
• SAE 1018 - low carbon equivalent in international standards, behaving like EN3B; weldability and case-hardening; good behaviour.
• SAE 1045 - medium carbon equivalent to EN8/C45, specified by SAE where it is required in a US or export specification.
• ST50-2 / ST52-3 - low-carbon, fine-grain structural steels, whose strength is based on controlled rolling and not on carbon content; the material used when both weldability and structural strength are required simultaneously, like fabrication and structural framing.

Testing and Certification

Each batch is checked against tests that are selected based on what does in fact influence the results of machining and fabrication, not a standard mill check:

• Checking the chemical composition against the desired grade, to ensure that carbon and manganese concentration are within the range.
• Tensile strength testing, yield and elongation testing especially on grades that are employed in structural or bearing components.
• Checking of squareness and corner radius throughout the section, as out-of-square bar appears as soon as a face is machined.
• Scale, laps and rolled-in defects on all four surfaces: Scale, laps and rolled-in defects on all four surfaces: Surface inspection Scale, laps and rolled-in defects on all four surfaces.
• Check on section size versus slit or rolling tolerance with dimensions.
• On request inspection by a third party, TUV, SGS, BV or a nominated agency.

Best Carbon Steel Square Bars Exporters in Maharashtra

We are a known Carbon Steel Square Bars Exporters in Maharashtra and supply fabricators and production units in the Gulf, southeast Asia, Africa and Europe. All consignments are supported by mill test certificates and EN 10204 3.1 or 3.2 certification where needed and third party inspection is offered as TUV, SGS or BV. The bar is filled and braced so that it does not bend or damage the corners or corrode during long haulage paths, such that squareness and surface quality upon arrival are the same as when it went out of stock.

Why Choose Us

Some of the reasons why fabricators and machine shops are continuing to buy their carbon steel square bar with us:

• Both Black and bright bar conditions B both surface condition either machining or as-is fabrication use.
• Broad range of section sizes in stock - sizes issued at your specification rather than at the mill standard run.
• Heat-continuity of stock - the same properties throughout a complete batch of machined or formed parts.
• Part-quantities issued - no minimums in mill tonnes of part-quantities holding up smaller or specialised orders.
• All batches tested and inspected - chemical, mechanical and squareness inspection prior to release.
• Director-based grade selection - 14 years of practical experience that corresponds to grade and section and application.
