Industrial Material
Why Specify ASTM A516 Grade 70 Boiler Plate Over General Carbon Steel?
In the fabrication of industrial boilers, gas storage systems, and pressure vessels, safety is paramount. Utilizing standard carbon steels (such as SS400 or A36) under high pressures and extreme temperature variations is a severe risk that fails to meet legal safety codes. Under high pressure, generic steel plates can suffer from fatigue and catastrophic failure.
ASTM A516 / ASME SA516 Grade 70 Boiler Plates are specifically engineered to eliminate these risks. Manufactured under strict chemical controls, these plates undergo precise heat treatments (such as Normalizing for thicker gauges) to deliver exceptional **notch toughness and high tensile strength**. This ensures the plate maintains its integrity at both elevated and low temperatures, guaranteeing maximum safety under pressure.
Guaranteed Quality with 100% Traceability (MTC)
For projects adhering to strict ASME Boiler and Pressure Vessel Codes, third-party inspection is a standard requirement. Trinity Dynamic supports your quality assurance with:
- Original Mill Test Certificates: Every boiler plate we supply is imported from world-class steel mills and is accompanied by its original Mill Test Certificate (MTC).
- Physical Heat Number Matching: The Heat Numbers stamped physically on the steel plates match the certificates perfectly, allowing inspectors and engineers to verify material compliance instantly.
Technical Specifications
Standard: ASTM A516 / ASME SA516 (Dual Certified to cover both structural and pressure-specific codes)
Primary Grade: Grade 70 (The industry standard in Thailand) and Grade 60
Delivery Condition: As Rolled / Normalized (Plates over 40 mm thick are normalized as standard)
Mechanical Properties (Typical ASTM A516)
| Grade | Tensile Strength (MPa) | Yield Strength (MPa) | Elongation (min %) |
|---|---|---|---|
| Grade 70 | 485 - 620 | ≥ 260 | 17 - 21% |
| Grade 60 | 415 - 550 | ≥ 220 | 21 - 25% |
*Note: Grade 70 is highly preferred in Thailand due to its superior tensile strength and higher pressure-bearing limits compared to Grade 60.
