With state-of-the-art manufacturing facilities and a strong dedication to quality, this company provides durable and corrosion-resistant fastening solutions that are perfect for both industrial and structural applications. Their Stainless Steel 446 Stud Bolts are engineered to endure extreme temperatures and tough environments, making them a great fit for chemical plants, power generation, and heat treatment industries. Kyaw Stainless prides itself on delivering superior performance, precision engineering, and compliance with international quality standards, serving both local and global markets with reliability and professionalism.
These Stainless Steel 446 Stud Bolts are primarily made up of iron and chromium (23–27%), along with small amounts of manganese, silicon, carbon, and molybdenum. This ferritic stainless steel grade is known for its outstanding oxidation resistance and thermal stability. The bolts boast high tensile strength, good hardness, and remarkable resistance to scaling at elevated temperatures of up to 1100°C. Thanks to their relatively low carbon content, they maintain their structural integrity without significant embrittlement. Their mechanical properties ensure they perform reliably over time, making them suitable for demanding high-temperature environments and corrosive industrial settings.
