ASME SA 516 GR.70 NACE Steel Plates – Engineered to Withstand Corrosive Conditions
Conquest Steel & Alloys is a trusted supplier of ASME SA 516 GR.70 NACE Steel Plates, designed for use in highly corrosive and sour service conditions. The plates are engineered to be in accordance with NACE MR0175 and MR0103 standards and are suitable for hydrogen sulfide (H₂S) service where resistance to sulfide stress corrosion and hydrogen-induced cracking (HIC) is important.
These pressure vessel-Grade plates are characterized by high tensile strength and excellent weldability, which makes them the first choice for fabricators undertaking critical pressure-containing equipment. SA 516 GR.70 NACE plates are delivered in a normalized state, which ensures higher toughness and ductility even under unfavorable operating conditions.
Key Features:
- Conforms to NACE MR0175 / MR0103
- HIC and SSC tested for sour gas service
- High tensile strength and impact resistance
- Excellent formability and weldability
- Supplied with Mill Test Certificates and third-party inspections
Supported by industry standards and in custom sizes, these plates are apt for pressure vessels, separators, boilers, and heat exchangers.
