Strategically located in the nation’s capital of Naypyidaw, Kyaw Stainless has built a strong reputation as a trusted manufacturer and supplier of high-grade stainless steel fasteners. We take particular pride in our Stainless Steel 301 Bolts, which are engineered for demanding situations. Our commitment lies in providing local industries with reliable, durable components that meet rigorous standards, ensuring your projects benefit from both superior material quality and the convenience of a dependable domestic source.
The strength of our 301 bolts comes from their specific composition, primarily a blend of chromium and nickel, which gives them a notable ability to work-harden rapidly. This means they become stronger and more resilient when shaped or used under stress. This results in bolts that offer an excellent combination of high tensile strength and good corrosion resistance, making them tougher than many common stainless grades while still maintaining the essential protective qualities needed for long-term performance.
