03X17H14M3 Stainless Steel in India — Russian Metals
INTRODUCTION OF 03X17H14M3
03X17H14M3, also known as the Russian GOST grade 03Х17Н14М3 or 03KH17N14M3, is a high-performance austenitic stainless steel specifically engineered for environments where both strength and corrosion resistance are critical. It retains its structural integrity even under severe cryogenic temperatures, which makes it highly dependable for industries requiring durability at -100°C and below. The alloy is also valued for its excellent weldability and ability to maintain toughness without becoming brittle, unlike many conventional grades of stainless steel.
