Ananka Group is one of the best ASTM A320 Grade L7 Stud Bolts Manufacturer, Supplier & Stockists in India. ASTM A320 Grade L7 Fasteners are manufactured using High Tensile material, which is desirable to manufacture fastener products bolts, studs and nuts, that can be used at a varied range of elevated temperatures in bolting applications.
ASTM A320 Gr L7 is the most common grade of A320 bolts. Bolts made using this material are extremely resistant to corrosion and a varied range of environmental conditions.
To achieve the requisite mechanical qualities, the bolts are subjected to a heat treatment process. ASTM A320 L7 bolts are medium carbon alloy steel bolts that have been quenched and tempered and are suitable for use in low temperature service, down to -100°F (-73°C). Steel alloyed with chromium, manganese, and molybdenum are used to make ASTM A320 L7 STUD BOLTS.
ASTM A320 L7 bolts are made from a low carbon, alloy steel that is quenched and tempered to achieve a high tensile strength of 120,000 psi. They are also coated with a corrosion resistant finish to protect against rust and other forms of corrosion.
Ananka Group is one of the premier Quality ASTM B638 grade 660 stainless steel alloy exporter in India. Ananka Group has been a trusted vendor as a ASTM A320 L7 Stud Bolts distributor & dealer in your country.
All the ASTM B638 grade 660 stainless steel alloy are used in various industries and its usages such as Mechanical Industry, Chemical Industry, Petrochemical Industry, etc. They are manufactured to meet the mechanical and chemical requirements of ASTM A320 specification. Each ASTM A320 Gr L7 Stud Bolts has different ability to form different application as per the design requirements and application.
The “L7” in the name refers to the type of tempering (quenching and tempering) that the bolts undergo after they are hot-forged. This process increases the strength and toughness of the bolts, making them suitable for use in low temperature environments. ASTM A320 L7 bolts are marked with the letter “L” followed by the number “7” to indicate their strength and tempering properties. They may also be marked with the ASTM specification and grade, as well as the manufacturer’s name or trademark.
