Harsh Metalloys, Mumbai, India, is a reputed supplier and maker of Stainless Steel 440C Stud Bolts, designed for high-strength, wear-resistant, and corrosion-resistant fastening. Our 440C stud bolts are used extensively in demanding industrial environments where hardness and dimensional stability are needed. Produced to international standards, these bolts are suitable for mechanical assemblies subjected to stress, abrasion, and corrosive substances. 440C stud bolts are provided by Harsh Metalloys in a wide variety of lengths, diameters, and thread types for the aerospace, defense, marine, and precision engineering sectors with long-lasting and reliable fastening solutions.
Stainless Steel 440C Stud Bolts are produced using a high-carbon martensitic stainless steel alloy with around 16–18% chromium and 0.95–1.2% carbon content. This gives them superior hardness, wear resistance, and fair corrosion resistance. Upon heat treatment, 440C exhibits high tensile strength of as much as 760 MPa and Rockwell hardness of approximately 58–60 HRC. Although it possesses good dimensional stability, it is inferior in corrosion resistance when compared with austenitic grades. Harsh Metalloys produces every stud bolt with precise manufacturing and heat treatment for maximum mechanical performance in demanding load-bearing applications.
