The company prides itself on precision engineering and a commitment to excellence, providing corrosion-resistant nuts that align with global industrial performance standards. With a strong emphasis on customer satisfaction and reliability, Kyaw Stainless delivers Stainless Steel 321H Nuts that are perfect for high-temperature settings and demanding applications. Their products are well-regarded for their sturdy construction, impressive finish, and compliance with international specifications, making them a trusted option across various industries in Myanmar and beyond.
Stainless Steel 321H Nuts are primarily made up of chromium (17–19%), nickel (9–12%), and titanium, with a touch of carbon to boost high-temperature strength. This material offers remarkable resistance to oxidation, intergranular corrosion, and scaling at temperatures up to 900°C. In terms of mechanical properties, these nuts boast a tensile strength of around 515 MPa, a yield strength of 205 MPa, and a hardness of about 95 HRB. Their high creep and stress-rupture strength make them perfect for elevated temperature environments where mechanical stability and durability are essential.
