ASTM Grade A612 Sheets Manufacturer, Supplier, Exporter & Stockist in india

ASTM Grade A612 Sheets are a type of high-strength, low-alloy carbon steel sheet commonly used in pressure vessel applications. These sheets are specifically designed to withstand elevated temperatures and high-pressure environments, making them suitable for a variety of industrial applications. The key mechanical properties of ASTM A612 sheets include a tensile strength ranging from 485 to 620 MPa (70 to 90 ksi) and a minimum yield strength of 275 MPa (40 ksi). These sheets typically exhibit an elongation of at least 23% in a 2-inch (50 mm) gauge length and a reduction of area of 40% or more. With a hardness level of 143 Brinell Hardness Number (BHN) maximum, they strike a balance between strength and formability.

In terms of chemical composition, ASTM A612 sheets typically contain carbon in the range of 0.20% to 0.25%, manganese between 1.00% and 1.50%, and silicon ranging from 0.15% to 0.50%. Phosphorus and sulfur content are limited to a maximum of 0.025% each, while nickel and chromium content are typically capped at 0.25% each. Molybdenum content is usually restricted to a maximum of 0.08%. This chemical composition, along with the heat treatment process of normalization, imparts the desired mechanical properties and high-temperature resistance to these sheets. It's important to note that the exact specifications for ASTM Grade A612 Sheets can vary depending on the manufacturer and the specific application requirements. Therefore, it's advisable to refer to the latest edition of the ASTM A612/A612M standard or consult with the supplier for detailed and up-to-date information on the product's properties and specifications.
