With a strong commitment to precision engineering, durability, and customer satisfaction, the company offers top-notch bars that are perfect for demanding industrial settings. Their products are made using cutting-edge manufacturing techniques and rigorous quality control, ensuring outstanding strength, corrosion resistance, and performance even at high temperatures. Kyaw Stainless is all about providing reliable stainless steel solutions that meet international standards, making them a go-to choice for clients in the construction, chemical processing, and power generation sectors.
Stainless Steel 321H Bars are an austenitic stainless steel alloy primarily made up of iron, chromium (17–19%), nickel (9–12%), and titanium (0.7–1%). The inclusion of titanium boosts resistance to intergranular corrosion, while the higher carbon content enhances strength at elevated temperatures. These bars boast impressive mechanical properties, featuring a tensile strength of about 515 MPa, yield strength of 205 MPa, and an elongation of 40%. They maintain their structural integrity and resist oxidation even when continuously exposed to high temperatures up to 900°C, making them perfect for heat-intensive industrial applications.
