A516Gr55 A516Gr60 Vessel Plate
ASTM A516 Grade 55 and Grade 60 are carbon steel plates for moderate- and lower-temperature pressure vessel service, governed by the ASTM A516/A516M standard. Both grades exhibit excellent notch toughness, weldability, and fatigue resistance.
Grade 60 offers higher strength compared to Grade 55 and is ideally suited for petrochemical equipment, reactors, and heat exchangers operating in moderate- or low-temperature pressure environments. In terms of mechanical properties, Gr55 has a tensile strength of approximately 380–515 MPa, while Gr60 ranges from 415–550 MPa.

Technical Provisions for Heat Treatment: ASTM A516 (Gr 55, 60, 65, 70)
Thickness ≤1.5 in. (40 mm):Plates of ASTM A516 Grades 55, 60, 65, and 70 are typically furnished in the as-rolled condition. However, these plates may also be ordered as normalized, stress-relieved, or normalized plus stress-relieved at the purchaser's option.
Thickness >1.5in. (40 mm):
Plates exceeding 1.5 in. (40 mm) in thickness shall be normalized.
Notch Toughness Requirements:
Unless otherwise specified by the purchaser, plates with a thickness≤1.5 in. (40 mm) shall be normalized when notch toughness requirements are mandated.

SA516 GR60, GR65,GR70N HIC Resistant Pressure Vessel Steel Plate
Hydrogen Induced Crack (HIC) Pressure Vessel Plate & Sheet supplier in China
ASTM A516 GR. 70 HIC (Hydrogen-Induced Cracking) plates are high-strength steel engineered to withstand hostile environments. They conform to the standardized specifications of the American Society for Testing and Materials (ASTM), ensuring their optimal performance, quality, and safety.
These plates are designed to work under severe sour service conditions where the steel is susceptible to hydrogen-induced cracking due to corrosive wet hydrogen sulfide. Hydrogen embrittlement, if unchecked, can lead to unexpected equipment failure, making HIC-resistant plates a crucial component in constructing pressure vessels and boilers.
Applications of A516 HIC Plates
These versatile plates are suitable for a wide array of applications, including:
Pressure Vessels
Boilers
Storage Tanks
Heat Exchangers
Their application is not limited to the oil and gas industry alone. Any sector confronting corrosive environments or requiring high-strength, HIC-resistant material can benefit from using ASTM A516 GR. 70 HIC plates.
