Punit Fasteners, a top-notch manufacturer and supplier based in Delhi, India, specializes in high-quality ASTM A193 B6X Stud Bolts. These bolts are designed for outstanding strength, durability, and performance, especially in high-temperature and corrosive settings. You’ll find them commonly used in industries like petrochemical, power generation, oil and gas, and industrial processing, where reliable fastening is a must, even under extreme conditions. Built to meet ASTM standards, these stud bolts boast impressive resistance to oxidation and scaling, along with solid mechanical strength. Punit Fasteners is committed to delivering precision-engineered products that consistently perform well in tough bolting situations.
The ASTM A193 B6X Stud Bolts are crafted from stainless steel akin to Grade 410, a martensitic stainless alloy that contains about 11.5–13.5% chromium, but with special treatments to boost heat and oxidation resistance. They undergo a quenching and tempering process to achieve a tensile strength of around 620 MPa and a yield strength of about 380 MPa, offering better toughness than standard B6 fasteners. While they provide moderate corrosion resistance, their standout features are excellent mechanical strength and thermal stability, making them perfect for high-stress bolting tasks in elevated temperature environments.
