Lecong Stainless, a well-respected manufacturer and supplier based in Da Nang, Vietnam, specializes in high-quality Stainless Steel 348H Tubing, tailored for demanding industrial applications. Renowned for its precision in manufacturing and strict compliance with international quality standards, Lecong Stainless caters to industries like power generation, petrochemical, and chemical processing. This tubing is crafted for outstanding durability, thermal stability, and oxidation resistance, ensuring it performs reliably even in the harshest conditions. With a commitment to innovation and customer satisfaction, the company delivers stainless steel tubing solutions that meet the rigorous demands of both local and global markets.
Stainless Steel 348H Tubing is an austenitic stainless steel alloy primarily made up of iron, 18–20% chromium, 9–12% nickel, along with carefully controlled amounts of titanium, carbon, manganese, and silicon. This unique composition offers remarkable resistance to high-temperature oxidation and creep, making it ideal for use in elevated temperature settings. Typically, the tubing boasts a tensile strength of about 515 MPa, a yield strength ranging from 205 to 310 MPa, and impressive elongation properties. Its exceptional thermal and corrosion resistance guarantees longevity and structural integrity in critical applications, even when exposed to heat and corrosive environments for extended periods.
