Abstract
1. Steel 30Kh3NM3FTs can be used in place of steel 3Kh2V8F for parts of presses with sections as large as 200 mm that operate under static applied loads. 2. Due to the high stability of austenite resulting from the addition of nickel, steel 30Kh3NM3FTs can be air hardened. 3. The ultimate tensile strength at standard and elevated temperatures, red hardness, creep strength, and other properties of steel 30Kh3NM3FTs are very similar to those of steel 3Kh2V8F, while the ductility and fracture toughness are higher. 4. Production tests have shown that the resistance of tools made of steel 30Kh3NM3FTs is equal to that of tools made from steel 3Kh2V8F.
