The Chrome Plated 38MnVS6 Tube is a non-heat-treated hollow piston rod made from 38MnVS6 micro-alloyed seamless steel tube, featuring high base strength and good machinability. Available in OD φ25–300 mm, up to 8000 mm long, it meets ISO f7 tolerance, an 850–1150 HV hard chrome layer, and 96-hour salt spray rating 9. Ideal for heavy-duty, lightweight or fluid-passage hydraulic cylinders, it supports full customization of dimensions, wall thickness, heat treatment and surface finishing.

The Nitrocarburized 38MnVS6 Rod features a QPQ-treated surface (diffusion zone 0.30–0.40 mm, white layer ≥25 µm) achieving ≥600 HV hardness without chrome plating. Available in φ6–300 mm, up to 8000 mm long, it meets ISO f7 tolerance and 200-hour salt spray rating 9. Built on high-strength 38MnVS6 micro-alloyed steel, this chrome-free rod provides excellent wear and corrosion resistance for heavy-duty hydraulic cylinders. Full customization supported.

The Chrome Plated 38MnVS6 Rod (Q&T + I.H.) combines a quenched & tempered core (260–330 HB) with an induction-hardened surface (55–62 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. Designed for heavy-duty cylinders, it offers high core strength and superior surface wear resistance, with full customization supported.

The Chrome Plated 38MnVS6 Rod (Induction Hardened) features a high-strength non-treated core (≤290 HB) with an induction-hardened surface of 55–62 HRC, depth 0.5–3.5 mm. Available in φ6–300 mm, up to 8000 mm long, it meets ISO f7 tolerance and an 850–1150 HV hard chrome finish with 96-hour salt spray rating 9. Its superior wear resistance is ideal for heavy-duty hydraulic cylinders. Full customization of dimensions, hardening depth, and surface treatments is supported.

The Chrome Plated 38MnVS6 Rod (Quenched & Tempered) features a micro-alloyed steel core treated to 260–330 HB, offering high strength and fatigue resistance. Available in φ6–300 mm, up to 8000 mm long, it meets ISO f7 tolerance and an 850–1150 HV hard chrome finish with 96-hour salt spray rating 9. Ideal for heavy-duty, high-pressure hydraulic cylinders, it supports full customization of dimensions, heat treatment and surface finishing.
