The Stainless Steel L43 fastener is a popular choice for fastening a variety of materials, including stainless steel. Its low carbon content makes it suitable for use in high-pressure applications and is generally used in bolts and nuts for the Petrochemical industry. 


Available in metric and imperial sizes, and standard and thread rolling diameters, the fastener is suitable for various applications. In addition, the L43 grade has a minimum carbon content of 0.28 percent.


Stainless Steel L43 bolts and studs are manufactured to ASTM A320. Both types are made from AISI 4340 and can reach a diameter of B8F for stud bolts. In contrast, Grade L7 bolts are limited to two-and-half inches in diameter. They share the same strength and tensile properties as their L7 counterparts, but are less expensive and have a shorter lead time. Besides, they have excellent corrosion resistance.


The ASTM A320 Grade L43 Alloy Steel bolts and screws are available at a wide range of prices. Unlike conventional fasteners, ASTM A320 Grade L43 bolts are made from AISI 4340 alloy steel. They can be made in a variety of sizes and are available at a wide range of prices. 


Whether you need an ASTM A320 Grade L43 bolt for your project or just want a more durable, long-lasting and attractive fastener, ASTM A320 grade L43 bolts and screws will fit your needs perfectly.
