The Chrome Plated 42CrMo Tube is a non-heat-treated hollow piston rod made from 42CrMo chromium-molybdenum alloy steel seamless tube, delivering exceptional base strength and hardenability. Available in OD φ25–300 mm, up to 8000 mm long, it features ISO f7 tolerance, an 850–1150 HV hard chrome layer, and 96-hour salt spray rating 9. Ideal for ultra-heavy-duty, lightweight or fluid-passage hydraulic cylinders in extreme conditions, it supports full customization of dimensions, wall thickness, heat treatment and surface finishing.

The Nitrocarburized 42CrMo Rod features a QPQ-treated surface (diffusion zone 0.30–0.40 mm, white layer ≥25 µm) achieving ≥700 HV hardness without chrome plating. Available in φ6–300 mm, up to 8000 mm long, it meets ISO f7 tolerance and 300-hour salt spray rating 9. Built on 42CrMo chromium-molybdenum steel with superior nitriding response, this chrome-free rod provides exceptional wear and corrosion resistance for the most demanding hydraulic cylinders. Full customization supported.

The Chrome Plated 42CrMo Rod (Q&T + I.H.) combines a quenched & tempered core (260–340 HB) with an induction-hardened surface (55–65 HRC, depth 0.5–3.5 mm) and hard chrome plating (850–1150 HV). Available in φ6–300 mm, up to 8000 mm long, ISO f7 tolerance, and 96-hour salt spray rating 9. Engineered for the most severe ultra-high-pressure, heavy-load cylinders, it delivers unmatched core strength and extreme surface wear resistance. Full customization supported.

The Chrome Plated 42CrMo Rod (Induction Hardened) combines a tough non-hardened core with an induction-hardened surface of 55–65 HRC, depth 0.5–3.5 mm. Available in φ6–300 mm, up to 8000 mm long, it meets ISO f7 tolerance with an 850–1150 HV hard chrome finish and 96-hour salt spray rating 9. Its extreme wear resistance is ideal for heavily abrasive hydraulic cylinders in mining and heavy machinery. Full customization of dimensions, hardening depth, and surface treatments is supported.

The Chrome Plated 42CrMo Rod (Quenched & Tempered) features a Q&T treated chromium-molybdenum alloy steel core of 260–340 HB, delivering exceptional strength and fatigue resistance. Available in φ6–300 mm, up to 8000 mm long, it meets ISO f7 tolerance with an 850–1150 HV hard chrome finish and 96-hour salt spray rating 9. Engineered for extreme heavy-duty and ultra-high-pressure hydraulic cylinders, it supports full customization of dimensions, heat treatment and surface finishing.
