Products Description
ASTM A516 Gr70 is a standard developed by the American Society for Testing and Materials (ASTM) to regulate the material properties and mechanical properties of carbon steel plates. This standard specifies the chemical composition, mechanical properties, heat treatment requirements, hardness requirements, impact toughness requirements, and other aspects of ASTM A516 Gr 70 carbon steel plate.ASTM A516 Gr 70 specification is for a tensile strength of 485 - 620 MPa. yield strength of a minimum of 260 MPa.These parameters ensure consistent performance and reliable safety during use. Compliant ASTM A516 Gr 70 steel plates can be used in a variety of demanding work scenarios.

Product Advantages
High Pressure Resistance
A516 Gr 70 boasts the highest strength grade within the A516 series, capable of withstanding medium-to-high pressure conditions while maintaining long-term operational stability without deformation.
Superior Low-Temperature Toughness
Through normalizing treatment and other processing methods, the steel plate exhibits excellent resistance to brittle fracture at low temperatures, suitable for operating temperatures ranging from -30°C to 450°C.
Weldability
Designed with low carbon and impurity content, A516 Gr 70 plates accommodate mainstream welding processes like SMAW/SAW/GMAW with minimal cracking susceptibility.
International Compliance
Compliant with ASTM/ASME/API standards, enabling direct use in export equipment and overseas projects.
ASTM A516 Gr 70 steel plate delivery state
Thickness less than 40mm steel plate:
The thickness of steel plate less than 40mm default delivery in the hot rolled state. Hot rolled state refers to the steel plate in the hot rolling mill after high temperature heating and rolling. This steel plate has a certain degree of strength and toughness, applicable to the surface quality requirements are not high occasions.
Thickness greater than or equal to 40mm steel plate:
The thickness of the steel plate is greater than 40mm default delivery in normalised condition. Normalising is a heat treatment process by heating the steel plate above a critical temperature and then cooling it in air. This improves the overall mechanical properties of the steel plate, including strength, toughness and weldability.
FAQ
Q: How to ensure quality?
A: The factory test certificate is provided with the shipment. If necessary, a third-party inspection can be accepted.
Q: How about your after-sales service?
A: As a professional steel export company, we provide promotion and technical support for all questions and questions.
Q: What is pressure vessel plate?
A: PVQ steel plate is used for the production of pressure vessels, which are closed containers designed to hold gases or liquids at a pressure substantially different than the ambient pressure.
Q: What is a steel pressure vessel?
A: A stainless steel pressure vessel is a type of container designed to hold its contents at pressures above 15 psig (that's 15 pounds of force applied per square inch, relative to atmospheric pressure). Pressure vessels withstand high pressures, applied externally or internally, with a large factor of safety.
Q: What grade of steel plate is used in pressure vessels?
A: There are multiple grades of Pressure Vessel Plate like A537 is the most common grade. The lesser known grades would include TC128, ASTM A612, and ASTM A285. The main difference between Pressure Vessel Steel Plate and Corten Steel Plate is in their appearance.
Q: What is the standard steel for pressure vessels?
A: While there are multiple grades of PVQ steel, ASTM A516 and ASTM A537 are most commonly used for pressure vessel applications due to their balance of strength and ductility.
