Inox Steel India is a manufacturer, supplier, and exporter of hex bars for valves and fittings, supplying high-integrity hexagonal bar stock for forged and machined valve components, pipe fittings, connectors, and pressure parts across India, GCC countries, the Middle East, Africa, Europe, and the Americas.
Hex bars used for valves and fittings are selected and processed to meet pressure-service requirements, with emphasis on internal soundness, metallurgical consistency, and machinability. These bars are commonly used for manufacturing valve bodies, bonnets, plugs, stems, forged fittings, and special pressure components.
Inox Steel India supplies valve-grade hex bars across carbon steel, alloy steel, stainless steel, duplex, super duplex, tool steel, and nickel alloy grades, conforming to applicable ASTM, ASME, EN, DIN, and IS standards.
Hex bars for valves and fittings are solid hexagonal bars used as raw material for forging or machining pressure-retaining components. Compared to general-purpose hex bars, valve-grade hex bars focus on clean internal structure, controlled chemistry, and suitability for pressure equipment standards.
These hex bars are typically supplied in forged, hot rolled, or bright condition, depending on the size, pressure class, and component design.
Hex bars are converted into valve and fitting components through forging and machining processes, followed by heat treatment and final inspection.
Typical Processing Route:
These characteristics ensure reliable performance, leak integrity, and long service life in valve applications.
Hex bars for valve and fitting applications are supplied in materials such as:
Material selection depends on pressure rating, operating temperature, corrosion resistance, and service media.
When selecting hex bars for forged or machined valve parts, the following parameters should be evaluated:
Correct selection ensures safe operation and regulatory compliance.
In India, valve-grade hex bars are widely used by industrial valve manufacturers, forged fitting producers, and pressure equipment fabricators, particularly in sectors such as oil & gas, power, petrochemical, and process industries.
Export demand is driven by API, ASME, and EN standard valve projects requiring traceable and certified raw material.
Valve-grade hex bars supplied by Inox Steel India are engineered for pressure-retaining forged and machined components where internal soundness, controlled chemistry, and reliable machinability are critical. These hex bars are used across valve types and fitting categories operating under pressure, temperature, and corrosive service.
Hex bars for valves and fittings are supplied to support forging allowance and precision machining.
(Refer to standard hex bar sizes in mm PDF and hex bar size chart in mm India for nominal AF dimensions.)
Weights are calculated on nominal AF size and vary with forging allowance and material density.
| AF Size (mm) | Indicative Weight (kg/m)* |
|---|---|
| 20 | 2.72 |
| 30 | 6.11 |
| 40 | 10.86 |
| 60 | 24.60 |
| 80 | ~43.70 |
| 100 | ~68.20 |
*Indicative only; actual weights depend on allowance and grade.
Pricing depends on:
Valve-grade processing typically carries a premium over general-purpose hex bars due to testing and quality controls.
