| 0.38-0.45 | ≤0.40 | 0.60-0.90 | ≤0.035 | ≤0.035 | 0.90-1.20 | 0.15-0.30 | |
| Specification of forged SCM440 steel bar | Hot Rolled: Dia.(mm)*L(mm)=14-200*2000-6000 | ||||||
| Forged: Dia.(mm)*L(mm)=210-800*2000-6000 | |||||||
| Application of forged SCM440 steel bar | (1) Commonly used for manufacturing 35CrMo higher than the required strength, large parts of the important sectional dimensions, such as axis, gear, connecting rod, transmission gears, the supercharger gear, engine cylinder, spring, spring clamps, 12-2000mm oil pipe fittings, fishing tools and instead of containing nickel steel high. (2) For main shaft of steamer,boly for 400 °C. Hummar shank. | ||||||
| Characteristic of forged SCM440 steel bar | (1) Chromium molybdenum high tensile steel with yield strength of 550N/mm2. (2) Chromium renders steel oil hardenable and increase hardenability. (3) Weldability suffers with increasing chromium content. (4) High temperature strength and high pressure hydrogenation properties are promoted by chromium and molybdenum. (5) Molybdenum significantly reduces temper brittleness. | ||||||
