Yaman Steel, a prominent manufacturer and supplier based in Mumbai, India, specializes in precision-engineered Stainless Steel 420 Stud Bolts that are celebrated for their durability, strength, and wear resistance. Crafted from martensitic stainless steel with a high carbon content, these stud bolts are perfect for fastening applications that require exceptional hardness and reliable performance under pressure. Yaman Steel is committed to strict quality control and follows international standards, ensuring that their SS 420 Stud Bolts provide a long service life even in tough industrial settings. They are widely trusted across various sectors, including engineering, petrochemical, construction, marine, and heavy machinery.
These Stainless Steel 420 Stud Bolts contain 12–14% chromium and a minimum of 0.15% carbon, which gives them impressive mechanical strength and wear resistance. Thanks to their martensitic structure, they can be heat-treated to boost hardness, tensile strength, and dimensional stability. These features make SS 420 Stud Bolts highly resistant to abrasion and capable of performing well in both high-pressure and moderately corrosive environments.
