Carbon Steel ASTM A516 Grade 70 Plates.
Everything you need to know about ASTM A 516 GR. 70 plates
Do you know why ASTM A516 GR.70 plates are popular among industrial application? If not, then this article is best for you as it entails you about the best quality and grade of plates in detail. These are medium carbon alloy plates that are mainly designed for boilers and pressure vessels. This grade of carbon alloy contains various elements and contents like phosphorus, sulfur, manganese, and silicon that are allowed by the ASTM grade in order to produce the hardest and strongest steel plates with ASTM specification.
Carbon steel is considered the high strength metal that is easily fabricated and easily welded into different forms. Well, if we talk about GR.70 plates they are considered best for their high tensile strength and good corrosion resistance. The trade name for the ASTM A516 GR.70 plates is PVQ plates and is highly popular among various industrial applications. These plates are also available in other grades like 60, 55 and 65. Furthermore, the plates are commonly used to fabricate the low-to-medium boilers, pressure vessels, and various processing equipment.
Well, if we talk about the Standard Specification for Pressure Vessel, Carbon Steel, for Moderate- and Lower-Temperature Service for these plates they are manufactured in accordance with both national and international standard and specification that includes ASTM A516 GR.70 grade. The thickness of these plates varies from 6mm to 120mm, whereas its width varies from 1000mm to 4500mm and above as per the requirement and demand of customers. These plates are often normalized from 1-1/2 form and size varies from ½ mm to 1mm. These plates are available in different forms and shapes that include boiler plates, hot rolled plates and pressure vessel plates.
There are various applications where these plates are used such as power generation, gas processing, oil drilling companies, heat exchangers, condensers, petrochemicals, and seawater equipment. These plates are manufactured with proper care and under the guidance of quality experts and using well-tested material which makes these plates to withstand easily in elevated environment and temperature.
ASTM A516 GR. 70 plates come across various tests and inspections that include raw material test, chemical analysis test, mechanical testing, hardness test, flattening test, high-temperature tension test, charpy V-notch impact test, pitting resistance test. On the other hand, when all these tests are over, manufacturers offer their customers various test documents and certification such as fumigation certificates, raw material test certificate, heat treatment charts, guarantee letter, quality assurance certificate, NABL approved lab certificate and third-party inspection report.

Well, the most important thing that is important and never ignored by both manufacturer and customer is packaging. Packaging plays a very role when it comes to choose a product. With it, complete marking about the product is done like size, length, and specification. This ASTM A516 GR. 70 plates are packed in best quality of plastic wrappers and then in wooden cases or boxes so as to prevent these plates from damage and rust until its last stage of production.
Supply Condition : As Rolled, Normalized Rolling, Furnace Normalizing, Vacuum Degassing, Simulated Post-Weld Heat Treatment or as per customer requirement.
Impact tested : -52° C
Tempering: Notch toughness can be improved by quenched cooling from hot rolling or normalizing by the supplier. If such a faster cooling rate is agreed upon between purchaser and supplier then the steel is also to be tempered at 1200 F.
Applications : Excellent choice for service in lower than ambient temperature applications, has excellent notch toughness and is used in both pressure vessels and industrial boilers.
Process of Manufacturing : Hot-Rolled (HR)
