Kyaw Stainless, a Naypyidaw, Myanmar-based company, is a well-known provider of top–grade stainless steel products, which include a comprehensive assortment of fasteners, tubes, sheets, and plates used in numerous industrial processes. Among the products offered by them, Stainless Steel 201 Fasteners are most prized for their durability, strength, and affordability. Made in Grade 201, these fasteners are produced in various shapes, such as bolts, nuts, washers, and screws, to suit a range of fastening requirements. Constructed from austenitic stainless steel, they have a balanced mix of chromium, nickel, and manganese that makes them perfect for use in construction, automobile, and manufacturing sectors.
Stainless Steel 201 Fasteners have a composition of Chromium (16-18%), Nickel (3.5-5.5%), Manganese (5.5-7.5%), Carbon (≤0.15%), and Silicon (≤1%), ensuring high strength and moderate corrosion resistance. Their mechanical properties include a tensile strength of ≥515 MPa, yield strength of ≥275 MPa, and elongation of ≥40%, providing durability and reliability. The physical properties include a density of 7.8 g/cm³, thermal conductivity of 16.3 W/m·K, and a melting point of 1400-1455°C. These properties make 201 fasteners suitable for structural, automotive, and industrial applications requiring strength, toughness, and resistance to wear.
