ASTM 904L & C-276 Corrosion Resistant Plate with Laser Cutting for Malaysian Oil & Gas Equipment Manufacturer
게시일: June 3, 2026
Project Background
A Malaysian oil and gas equipment fabricator serving offshore platforms in the South China Sea required high-performance corrosion-resistant plates for heat exchangers, pressure vessels, and chemical injection skids. The operating environment included exposure to sour gas (H2S), chlorides, and acidic process fluids.
Challenge
- Severe corrosion conditions: H2S, CO2, chlorides, and organic acids
- High-pressure equipment requiring thick-gauge plates with guaranteed mechanical properties
- Complex flange and nozzle cutouts demanding precision laser cutting
- Full material traceability and NDT documentation required
- Urgent project timeline with penalty clauses for late delivery
Solution
| Parameter | Specification |
|---|---|
| Materials | ASTM 904L (UNS N08904), C-276 (UNS N10276) |
| Form | Hot Rolled Plate |
| Thickness | 5mm - 60mm |
| Processing | CNC Laser Cutting + Edge Preparation |
| Standards | ASTM B575 (C-276), ASTM A240 (904L), NACE MR0175 |
| Certification | ISO 9001, SGS, TUV, BV + PMI Testing |
| Delivery | 16 days after deposit (expedited) |
904L super austenitic stainless steel was specified for chloride-rich process environments, while C-276 nickel alloy was selected for the most aggressive H2S and acid service conditions. All plates underwent Positive Material Identification (PMI) testing before shipment. Laser cutting was performed to tolerances of ±0.2mm with NDT edge inspection.
Results
- Expedited delivery in 16 days — 4 days ahead of committed schedule
- 100% PMI pass rate with full chemical verification
- Zero material non-conformance reports from client QC inspection
- Supplier approved for inclusion in client approved vendor list for exotic alloys
