This achievement underscores our commitment to standardized, streamlined, and professional manufacturing and inspection processes. Every product undergoes stringent quality checks to ensure optimal performance before delivery.
Introduction to 347 Stainless Steel
347 stainless steel is a niobium-stabilized austenitic stainless steel renowned for its exceptional resistance to high-temperature corrosion and oxidation. Its unique composition and stability make it ideal for demanding environments, particularly in aerospace, energy, and chemical processing sectors.
Key 347 Chemical Composition
The alloy’s corrosion resistance stems from a precisely balanced formula:
| Element | 347 | 347H |
| Cr | 17.0-24.0 | 17.0-24.0 |
| Ni | 9.0-13.0 | 9.0-13.0 |
| C | 0.08 max | 0.04-0.1 |
| Mn | 2.0 max | 2.0 max |
| P | 0.045 max | 0.045 max |
| S | 0.03 max | 0.03 max |
| Si | 0.75 max | 0.75 max |
| Co+Ta | 10 * (C + N) -1.00 | 8* (C + N) -1.00 |
347 Mechanical Properties
347 stainless steel delivers robust performance across temperatures:
| Material | Yield Strength (ksi) | Tensile Strength (ksi) | Tensile Strength (ksi) | Hardness HB |
| Alloy 347 Sheet (Sol Trtd) AMS 5512 | 25 | 70-105 | 40 | - |
347 Applications
347 stainless steel excels in high-stress, corrosive environments:
-
Aerospace: Jet engine exhaust systems and components (resists thermal cycling up to 925°C).
-
Petrochemical: Crackers, heat exchangers, and Pipelines (immune to chloride and acid attacks).
-
Energy: Boiler tubes and nuclear reactor parts (maintains integrity under prolonged heat).
Its weldability without post-treatment and superior intergranular corrosion resistance make it a cost-efficient, long-term solution.
