ASME SA 516 GR.60/70N Dual Certified Plates refer to specific types of carbon steel plates used in pressure vessel and boiler applications. Here’s a breakdown of the term:
ASME: This stands for the American Society of Mechanical Engineers, which is a professional organization that establishes codes and standards for various engineering applications. ASME codes are widely used in the design and construction of pressure vessels and boilers.
SA 516: ASME SA 516 is a specification that sets the requirements for carbon steel plates used in pressure vessel applications. It outlines the standards and specifications for these plates to ensure their suitability for use in high-pressure and varying-temperature environments.
GR.60/70N: These are different grades of carbon steel. SA 516 GR.60 and SA 516 GR.70N are two distinct grades, each with its own set of mechanical properties. GR.60 is typically used for lower-temperature applications, while GR.70N is used for higher-temperature applications. The “N” in GR.70N stands for normalized, indicating that it has undergone a specific heat treatment to improve its properties.
Dual Certified: The term “dual certified” indicates that these plates meet the specifications and standards for both GR.60 and GR.70N grades. This means that they are designed to be versatile and suitable for a range of temperature and pressure conditions. Dual certification allows for more flexibility in selecting the appropriate plate for a given application.
>> Equivalent Grade ASME SA 516 GR.60/70N DUAL CERTIFIED PLATES
Equivalent grades for ASME SA 516 GR.60/70N Dual Certified Plates in other international standards are typically used to ensure that the same material specifications can be met outside of the United States. Equivalent grades may have slightly different designations and terminology but have similar chemical and mechanical properties. It’s essential to consult with your materials engineer or refer to specific standards and codes to determine the exact equivalent grades for your application. However, here are some commonly used equivalent grades:
EN10028-3 P275N/P275NH/P275NL1/P275NL2: These European standard grades are often considered equivalent to ASME SA 516 GR.60. EN10028-3 is used for pressure vessel applications in European countries.
EN10028-3 P355N/P355NH/P355NL1/P355NL2: These European standard grades are often considered equivalent to ASME SA 516 GR.70N. EN10028-3 is also used for pressure vessel applications in European countries.
DIN 17155 HII/HII P265GH: These are German standards for pressure vessel steel and are equivalent to ASME SA 516 GR.60.
DIN 17155 17Mn4/19Mn6: These German standards are equivalent to ASME SA 516 GR.70N.
BS 1501 161-430A/161-430B: These British standards are often considered as equivalents to ASME SA 516 GR.60 and GR.70, respectively.
JIS G3115 SPV235/SPV355: These Japanese Industrial Standards (JIS) are used for pressure vessels and can be considered as equivalents to ASME SA 516 GR.60 and GR.70, respectively.

Testing was done-
Mill Test Certificate (MTC) or Material Test Report (MTR): This document provides detailed information about the chemical composition, mechanical properties, and other material specifications of the plates. It is issued by the manufacturer and serves as evidence that the material meets the required standards.
Certificates and documentation-
Certificate of Conformance: This is a document that certifies that the supplied plates conform to the relevant ASME SA 516 specifications. It confirms that the materials meet the requirements of the ASME code.
Dual Certification Statement: As the plates are dual certified (GR.60 and GR.70N), a statement or certificate should explicitly indicate this dual certification. It confirms that the plates meet the requirements of both grades.
Heat Treatment Records: If the plates have undergone specific heat treatments, such as normalizing for GR.70N, records of these treatments should be included to verify that they were conducted correctly.
Material Traceability: Documentation should provide information about the source of the materials, including details about the steel manufacturer and the specific batch or lot of plates.
Wrapping is done-
In the context of materials and steel plates, the term “wrapping” typically refers to the packaging and protection of the plates for shipping and storage. When ASME SA 516 GR.60/70N Dual Certified Plates are prepared for transport or storage, they are typically wrapped or packaged to protect them from environmental factors and physical damage during handling and shipping.
