These fasteners are celebrated for their remarkable strength and durability, designed to meet the rigorous demands of industrial, marine, and mechanical applications. Emilio Stainless offers precision-engineered 440C stud bolts that guarantee outstanding performance even in high-stress and corrosive environments. With a strong commitment to quality, reliability, and customer satisfaction, the company ensures that its products meet international standards, making them perfect for both local and global projects.
Stainless Steel 440C Stud Bolts are primarily made of iron, containing about 16–18% chromium, 0.95–1.20% carbon, along with trace amounts of manganese, molybdenum, and silicon. This martensitic stainless steel grade is known for its high hardness, strength, and wear resistance after heat treatment. Mechanically, 440C boasts a tensile strength of up to 760 MPa and excellent corrosion resistance, especially against mild acids and water. Its ability to maintain strength and dimensional stability at elevated temperatures makes it a top choice for precision fastening applications.
