Kyaw Stainless is a well-respected manufacturer and supplier located in Naypyidaw, Myanmar, known for its top-notch Stainless Steel 317 Bolts. These bolts are crafted to perform exceptionally well in tough industrial settings where strength, resistance to corrosion, and durability are essential. Made from molybdenum-bearing austenitic stainless steel, Stainless Steel 317 boasts outstanding resistance to pitting, crevice corrosion, and chemical damage. At Kyaw Stainless, we ensure that each bolt adheres to strict quality standards and precise dimensions. Our 317 bolts are perfect for applications that face harsh chemicals, high temperatures, and corrosive environments, guaranteeing long-lasting reliability and impressive mechanical strength.
Stainless Steel 317 Bolts consist of chromium (18–20%), nickel (11–15%), and molybdenum (3–4%), with carbon capped at a maximum of 0.08%. This alloy provides a tensile strength of around 515 MPa and a yield strength of about 205 MPa, along with 35% elongation. Its hardness typically measures 85 HRB, ensuring remarkable durability and toughness. The addition of molybdenum significantly boosts corrosion resistance, particularly in chloride and acidic settings. These characteristics make Stainless Steel 317 Bolts highly resistant to pitting, oxidation, and stress corrosion cracking, even under demanding service conditions.
