AISI 4317 (25CrMo4) Alloy Steel Round Bar & Forging Stock
Short Description:
AISI 4317 / 25CrMo4 (1.7218) is a chromium-molybdenum alloy steel known for its high strength, toughness, and good hardenability. It is widely used for forged components such as shafts, gears, and connecting rods in automotive and mechanical applications.
AISI 4317 Alloy Steel Round Bar:
AISI 4317, also known as 25CrMo4 or DIN 1.6582, is a low-alloy chromium-molybdenum steel offering excellent strength, toughness, and wear resistance. It is commonly used in the production of high-performance forged parts such as shafts, gears, crankshafts, and connecting rods. Supplied in hot rolled or forged condition, this steel grade is suitable for quenching and tempering to achieve high mechanical properties. Saky Steel provides round bars and custom forgings with precise dimensions and full traceability according to international standards.
