ASTM A 516 GR.70 NACE Steel Plates – High Strength Boiler Quality Plates for Sour Service
Conquest Steel & Alloys supplies high-quality ASTM A 516 GR.70 NACE Steel Plates, which are well-suited for use in pressure vessels that will be operating in the presence of hydrogen sulfide (H₂S). The plates conform to the stringent specifications of NACE MR0175 and ISO 15156 and provide great resistance to sulfide stress cracking (SSC) under sour service conditions.
ASTM A516 GR.70 NACE plates are produced with controlled sulfur and are normalized for better toughness. Their high tensile strength and durability suit them for use in oil refineries, petrochemical industries, and offshore platforms.
Key Features:
- Compliance with NACE MR0175/ISO 15156
- Good weldability and notch toughness
- HIC and SSC tested
- Normalized condition with low sulfur
- Supplied with IBR, MTC, and third-party inspection reports
These plates are particularly ideal for conditions demanding extra protection against hydrogen-induced damage.
