4130 Steel Forging Overview
AISI 4130 is a chromium-molybdenum alloy steel commonly selected for forged components requiring a practical combination of strength, toughness and reliable processing performance.
We supply custom 4130 steel forgings in the form of shafts, bars, rings, blocks and other industrial components according to customer drawings and technical specifications.
Production requirements are reviewed according to the required dimensions, unit weight, machining allowance, mechanical properties, testing scope and documentation requirements.
