F316 is an austenitic stainless steel grade containing chromium, nickel and molybdenum.
The nominal alloy composition provides the material characteristics required for a wide range of industrial equipment applications. F316 is commonly specified for process equipment, piping components, valves, flanges and other fabricated or forged parts.
For products manufactured to ASME SA182 F316, chemical composition, mechanical properties and heat-treatment requirements shall comply with the applicable edition of ASME SA182 / ASTM A182 and the purchase specification.
Typical F316 chemical requirements under ASTM A182 are shown below:
| Element | F316 Requirement |
|---|---|
| C | ≤0.080% |
| Mn | ≤2.00% |
| Si | ≤1.00% |
| P | ≤0.045% |
| S | ≤0.030% |
| Cr | 16.0–18.0% |
| Ni | 10.0–14.0% |
| Mo | 2.0–3.0% |
| Fe | Balance |
The actual chemical composition shall be verified against the applicable ASME SA182 edition and material certificate for the supplied heat.
The mechanical properties of ASME SA182 F316 forgings shall meet the requirements of the applicable material specification.
| Property | Requirement |
|---|---|
| Tensile Strength | According to ASME SA182 F316 |
| Yield Strength | According to ASME SA182 F316 |
| Elongation | According to ASME SA182 F316 |
| Reduction of Area | According to Applicable Specification |
| Hardness | According to Applicable Specification |
| Heat Treatment | Solution Heat Treatment as Specified |
The final certified values should be taken from the MTC for the actual heat and product condition.
The sight glass frame flange is designed to provide a mechanical mounting and sealing interface for a sight glass assembly.
The typical structure consists of a circular forged body with a central viewing opening and mounting holes.
The internal opening is machined according to the required sight glass diameter and viewing area.
