Stainless Steel Grades & Applications
We stock and process various stainless steel grades, including Austenitic, Ferritic, Duplex, and Super Duplex classes, to provide optimal resistance to acids, chemicals, and extreme temperatures.
| Grade Family | Common Grades | Key Features & Applications |
|---|---|---|
| Austenitic (Standard) | SS 304 / 304L, SS 316 / 316L | High corrosion resistance, excellent formability. Used in food processing, chemical piping, and general construction. |
| High Temperature | SS 321 / 321H, SS 347 / 347H, SS 310S / 310H | Stabilized with Titanium/Niobium or high Chromium-Nickel. Excellent creep strength at high temperatures. Used in heat exchangers and boiler pipes. |
| Super Austenitic | SS 904L, SMO 254 (UNS S31254) | High resistance to chloride stress corrosion cracking and pitting. Used in paper pulp, sulfuric acid processing, and marine applications. |
| Duplex & Super Duplex | Duplex 2205 (S32205), Super Duplex 2507 (S32750) | Combining austenitic and ferritic structures for double the strength of standard grades. Extreme resistance to localized corrosion. Used in oil exploration and marine piping. |

Quality Assurance & Testing
At Grevinox Overseas, quality is our foremost priority. Every pipe and tube undergoes rigorous inspection and testing to conform to industrial and structural requirements before dispatch. We provide Mill Test Certificates (MTC) according to EN 10204 3.1 standards with all supplies.
- Hydrostatic Test: Verifies the pressure-retaining capacity of pipes and checks for any leakages under high pressure.
- Eddy Current & Ultrasonic Test: Non-destructive testing (NDT) to inspect sub-surface cracks, flaws, and defects.
- Positive Material Identification (PMI): Spectro testing to analyze and confirm the exact chemical composition of alloys.
- Mechanical Testing: Includes Tensile, Yield strength, Elongation, Flattening, and Hardness tests to verify structural strength.
- Visual & Dimensional Check: Checks length, straightness, outer diameter, wall thickness, and surface finishes.
- Third-Party Inspection (TPI): We welcome TPI from reputed global agencies such as TUV, DNV, Bureau Veritas, SGS, LLOYDS, etc.
