17CrNiMo6 ALLOY STEEL ROUND BARS
17CrNiMo6 steel round bars are high-performance case-hardening alloy steel products used for demanding engineering applications where superior toughness, high tensile strength, and excellent wear resistance are required. This grade — also specified under DIN 1.6587 and equivalent to 18CrNiMo7-6 in EN standards — is specially formulated with chromium, nickel, and molybdenum to enable deep hardening and strong core toughness after heat treatment. These round bars are widely used in manufacturing precision shafts, gears, spindles, and heavy machinery components that operate under high stress and cyclic loads.
17CrNiMo6 ALLOY STEEL FLAT BARS
17CrNiMo6 flat bars provide excellent structural strength combined with high surface hardness and core toughness. The material’s alloy composition and heat-treatable nature make it suitable for precision flat bar applications such as industrial tool frames, load-bearing parts, and heavy engineering equipment components. These flat bars can be carburized and tempered as per application requirements, delivering a balance of wear resistance and mechanical reliability for long-service performance.
17CrNiMo6 ALLOY STEEL BLOCKS
17CrNiMo6 steel blocks are solid sections used where large, robust steel shapes are needed before machining and finishing. These blocks have superior forgeability, good dimensional stability, and respond well to heat treatment cycles. They are ideal for producing large industrial parts such as heavy flanges, gear blanks, bearing housings, and structural components for machinery that require a tough core and high strength throughout the section.
