SCM420 is a low-carbon chromium-molybdenum alloy structural steel. Characterized primarily by its suitability for carburizing and quenching—combined with high toughness—it is widely utilized in load-bearing and wear-resistant components such as gears, shafts, fasteners, and mold inserts.
vacuum oil quenching of 4140 steel (AISI/SAE 4140) is the standard process for achieving high hardness, high strength, low distortion, and freedom from oxidation and decarburization.
In advanced vacuum metallurgy, the precision of gas delivery systems determines the consistency of finished products and the repeatability of complex thermochemical cycles.
