Ganpat Metal Pvt. Ltd. handles Carbon Steel Instrumentation Valves requirements for industrial process lines, pressure measurement systems, fluid control equipment and plant instrumentation. Carbon steel valves are selected for their material strength, pressure-containing design and compatibility with the operating medium and service conditions.
The product specification can include ASTM A216 cast carbon steel and ASTM A694 forged carbon or alloy steel, depending on the valve construction and required service. These standards cover different product forms and must be matched to the specified valve design.
For forged carbon steel requirements under ASTM A105, see our A105 Instrumentation Valves page.

Material selection: ASTM A216 covers carbon steel castings for valves and other pressure-containing parts. ASTM A694 covers carbon and alloy steel forgings for high-pressure transmission service. The grade must be specified alongside the standard because chemical composition and mechanical properties differ between grades.
Chemical composition depends on the specified grade. The following table gives the principal composition limits for ASTM A216 Grade WCB cast carbon steel. ASTM A694 forgings have grade-specific chemical requirements and should not be inferred from the WCB casting table.
| Element | ASTM A216 Grade WCB |
|---|---|
| Carbon (C), max. | 0.30% |
| Manganese (Mn), max. | 1.00% |
| Silicon (Si), max. | 0.60% |
| Phosphorus (P), max. | 0.040% |
| Sulfur (S), max. | 0.045% |
The following are the principal tensile requirements for ASTM A216 Grade WCB cast carbon steel. Mechanical requirements for ASTM A694 depend on the selected F-grade.
| Mechanical Property | ASTM A216 Grade WCB |
|---|---|
| Tensile Strength, min. | 70,000 psi (485 MPa) |
| Yield Strength, min. | 36,000 psi (250 MPa) |
| Elongation in 2 in. (50 mm), min. | 22% |
For example, ASTM A694 F52 specifies a minimum yield strength of 52 ksi (360 MPa), a minimum tensile strength of 66 ksi (455 MPa) and a minimum elongation of 20%. The material grade, product form and heat-treatment condition must match the purchase specification.
The equivalent-grade designation depends on the material specification and product form. The following table identifies the commonly used designations for ASTM A105 forged carbon steel.
| Standard | Grade / Designation | UNS | Werkstoff Number |
|---|---|---|---|
| ASTM / ASME | A105 / SA105 | K03504 | 1.0460 |
UNS K03504 and Werkstoff No. 1.0460 are commonly associated with ASTM A105 carbon steel forgings. They should not be used as universal equivalents for ASTM A216 castings or all ASTM A694 grades. For ASTM A216 cast valves, specify the required casting grade (e.g. WCB). For ASTM A694 forgings, identify the required F-grade designation.
| Connection Type | Description |
|---|---|
| NPT | National Pipe Taper thread |
| BSPT | British Standard Pipe Taper thread |
| Screwed Parallel | Parallel-threaded connection |
| Screwed Taper | Taper-threaded connection |
| Socket Weld | Welded connection for compatible pipe and valve designs |
| Flanged End | Flanged connection defined by the applicable dimensional standard |
NPT, BSPT and parallel-thread connections have different geometries. The enquiry should identify the exact thread designation, connection size and male or female arrangement.
| ASME Pressure Class | Designation |
|---|---|
| Class 150 | 150 |
| Class 300 | 300 |
| Class 600 | 600 |
| Class 900 | 900 |
| Class 1500 | 1500 |
| Class 2500 | 2500 |
These are nominal ASME pressure-class designations, not direct working-pressure values in psi. The allowable working pressure depends on the valve design, material group and operating temperature under the applicable standard.
For quotation accuracy, provide the material standard/grade, valve type, size, pressure class, end connection, quantity and any inspection requirements. These details determine the applicable manufacturing and documentation requirements.

Carbon steel instrumentation valves are selected according to the required flow function, instrument connection and pressure-containing design.
Also available: Carbon Steel Bleed and Vent Valves for releasing trapped pressure or venting an instrument line according to the valve design. The required valve function should be stated in the enquiry.
Inspection requirements should address both the material supplied and the completed valve. Typical documentation includes chemical composition analysis, tensile and yield strength testing, Material Test Certificate, heat-treatment records where required, dimensional and visual inspection, pressure testing, seat-leakage testing, non-destructive examination when specified, material traceability records and third-party inspection report when required.
The material grade should be selected according to the process medium, operating pressure, temperature and relevant piping or equipment specification. Carbon steel is not suitable for every corrosive medium, so the material selection must account for the actual service conditions.
