Stainless Steel 317 Flanges Chemical Composition Mechanical Properties and Service Reliability
Metalica Forging Inc, the company that has developed high performance piping components in harsh industrial settings, is a credible Stainless Steel 317 Flanges Manufacturer that provides a solution to high level corrosions resistance and mechanical strength. Grade 317 stainless steel contains more molybdenum and is therefore particularly appropriate with aggressive chemical and marine applications as well as those in very high temperatures. These flanges are common in petrochemical plants, refineries, and process industries where acids and chloride resistance are very important. Spade flanges are mostly used to maintain the safe operations and control the flow of such systems in case of isolation and line-blanking needs.
The stainless steel 317 components were designed to be used in high-pressure and thermal conditions and offer good service life in harsh service environments. They come in many pressure classes, sizes and facing types to accommodate complicated piping arrangements and important installations. In pipelines with a large diameter and those with significant loads, Anchor flange designs are common to eliminate the occurrence of the axial movement and structural stability. As a combination, the flangle solutions make the difference to safe connections, working safety, and reliable performance in the heavy engineering and process-oriented industries.
Stainless Steel 317 Flanges – Technical & Material Grade Table
| Material | Grade | Standard | Pressure Class | Size Range | Facing Type | Temperature Capability | Typical Service Area |
|---|---|---|---|---|---|---|---|
| Stainless Steel | ASTM A182 F317 | ASME B16.5 | Class 150–600 | ½″ – 24″ | RF | Up to 600°C | Chemical processing |
| Stainless Steel | ASTM A182 F317L | ASME B16.5 | Class 150–600 | ½″ – 24″ | RF | Up to 600°C | Acidic & chloride media |
| Stainless Steel | ASTM A182 F317 | ASME B16.47 | Class 150–300 | 26″ – 48″ | RF | Up to 600°C | Large diameter pipelines |
| Stainless Steel | ASTM A182 F317L | ASME B16.5 | Class 150–900 | ½″ – 24″ | RTJ | High-pressure systems |
- Industrial Use: It is used in piping systems that deal with aggressive chemicals, chlorides and acidic media that exhibit premature corrosion in normal stainless grades.
- Quality Characteristics: More molybdenum content is better in resisting pitting and crevice corrosion and controlled forging is used to provide stable performance in the fluctuating temperatures.
- Grade Details: The material fabricated to conform to ASME B16.5 and B16.47 dimensional standards of pressure piping manufactured in ASTM A182 F317 / F317L.
- Other Considerations: Retains mechanical strength and surface stability in reducing and oxidizing environments and hence it is used in long cycle operations in industries.

Stainless Steel 317 flanges are chosen on the basis of harsh environments; where high amount of molybdenum is desired to resist pitting and chemical corrosion. They are also stable in their performance, which implies that they can be used in services that are aggressive and high temperature. In the process of evaluating the material, Titanium Gr 1 Flanges are occasionally used in the event that there is a necessity to reduce weight and substantial corrosion resistance is necessary. On a B2B Platform, such properly designed tables can assist the engineers and the buyers to evaluate grades, pressure ratings and service suitability conveniently to achieve long term system reliability.
