Dang Steel, a top-notch manufacturer and supplier based in Da Nang, Vietnam, specializes in high-quality Alloy Steel T12 Tubing, crafted to meet ASTM/ASME standards. This tubing is designed to deliver outstanding high-temperature strength, corrosion resistance, and long-lasting durability, making it perfect for applications in power generation, petrochemicals, and refineries. Thanks to their advanced manufacturing techniques and rigorous quality control, Dang Steel guarantees precise dimensions, mechanical reliability, and consistent performance. Their T12 tubing is a popular choice in both domestic and international markets for piping systems that demand exceptional resistance to thermal stress, pressure, and oxidation.
Alloy Steel T12 Tubing is made from T12 alloy steel, which includes about 0.05–0.15% carbon, 1.0–1.5% chromium, and 0.44–0.65% molybdenum, along with carefully controlled amounts of manganese, silicon, phosphorus, and sulfur. This specific blend results in impressive tensile strength (415–585 MPa), a minimum yield strength of 205 MPa, and at least 30% elongation. The alloying elements boost creep resistance, high-temperature strength, and oxidation resistance, making T12 tubing ideal for extended use under high temperatures and pressures.
