The Chrome Plated EN8 Tube is a non-heat-treated hollow piston rod made from EN8 seamless steel tube, offering balanced strength and toughness. Available in OD φ25–300 mm, up to 8000 mm long, it features ISO f7 tolerance, a hard chrome layer of 850–1150 HV, and 96-hour salt spray rating 9. Ideal for lightweight, fluid-passage hydraulic cylinders, it supports full customization of dimensions, wall thickness, heat treatment and surface finishing.

The Nitrocarburized EN8 Rod features a QPQ-treated surface (diffusion zone 0.30–0.40 mm, white layer ≥25 µm) delivering ≥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 EN8 steel with balanced strength and toughness, this chrome-free rod provides excellent wear and corrosion resistance for hydraulic cylinders and outdoor equipment, with full customization supported.

The Chrome Plated EN8 Rod (Q&T + I.H.) combines a quenched & tempered core (220–310 HB) with an induction-hardened surface (50–60 HRC, depth 0.5–3.5 mm) and hard chrome plating (850–1150 HV). Available in φ6–300 mm, up to 8000 mm long, it meets ISO f7 tolerance and 96-hour salt spray rating 9. Designed for heavy-duty hydraulic cylinders, it offers a balanced combination of core toughness and surface wear resistance, with full customization supported.

The Chrome Plated EN8 Rod (Induction Hardened) features a non-hardened core with a high-hardness surface layer of 50–60 HRC, hardened to a depth of 0.5–3.5 mm. Available in φ6–300 mm diameters and lengths up to 8000 mm, it meets ISO f7 tolerance with an 850–1150 HV hard chrome finish and 96-hour salt spray rating 9. Ideal for wear-intensive hydraulic cylinders, it offers full customization of dimensions, hardening depth, and surface treatments.

The Chrome Plated EN8 Rod (Quenched & Tempered) features a Q&T treated core of 220–310 HB, offering balanced strength and toughness. Available in φ6–300 mm, up to 8000 mm long, it meets ISO f7 tolerance and a hard chrome layer of 850–1150 HV. With 96-hour salt spray rating 9, it is a reliable choice for medium-to-high-pressure hydraulic cylinders. Full customization of dimensions, heat treatment and surface finishing is supported.
