1. What is ASME SA240 Gr 444 (S44400)?

ASME SA240 Gr 444, also known as UNS S44400, is a ferritic stainless steel alloy with 17.0-20.0% chromium, 1.75-2.50% molybdenum, and columbium (niobium) plus tantalum stabilization (0.2+4xC-0.80%). The high molybdenum content and stabilization enhance its resistance to pitting, crevice corrosion, and stress corrosion cracking, while the low carbon content ensures excellent weldability. ASME SA240 Gr 444 material is ideal for applications requiring superior corrosion resistance in aggressive environments, such as water tanks, heat exchangers, and chemical processing equipment.

Compared to ASME SA240 Gr 439, ASME SA240 Gr 444 offers significantly better corrosion resistance due to higher molybdenum content, approaching the performance of austenitic grades like ASME SA240 Gr 316 in certain environments, while maintaining cost-effectiveness.

Gangsteel’s ASME SA240 Gr 444 stainless steel plate is engineered for industries seeking high-performance, corrosion-resistant solutions, offering a superior alternative to grades like ASME SA240 Gr 436 or ASME SA240 Gr 430.
