Yaman Steel, a trusted manufacturer and supplier in Mumbai, India, offers high-performance Stainless Steel 440B Stud Bolts, crafted for industries that demand strength, precision, and durability. Made from high-carbon martensitic stainless steel, these stud bolts provide exceptional hardness, tensile strength, and resistance to wear. They are widely used in sectors where secure fastening and reliability under stress are crucial. At Yaman Steel, every SS 440B Stud Bolt is manufactured with strict quality standards, ensuring long service life, consistency, and reliable performance in demanding industrial applications, making them a preferred choice across engineering and heavy-duty environments.
Stainless Steel 440B Stud Bolts are composed of 16–18% chromium, high carbon content, and trace elements like manganese, silicon, and molybdenum. This composition offers superior hardness and strength while maintaining moderate corrosion resistance. After heat treatment, SS 440B achieves high Rockwell hardness and excellent tensile strength, making it highly resistant to wear and abrasion. These mechanical properties ensure the stud bolts perform effectively in extreme load-bearing applications. Their toughness, durability, and stability make them reliable for use in heavy-duty and high-temperature environments.
