The Chrome Plated C50 Tube is a non-heat-treated hollow piston rod made from C50 high-carbon seamless steel tube, offering higher core strength and superior hardenability. 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 72-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 C50 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 120-hour salt spray rating 9. Built on C50 high-carbon steel with superior core strength, this chrome-free rod provides excellent wear and corrosion resistance for demanding hydraulic cylinders and outdoor equipment, with full customization supported.

The Chrome Plated C50 Rod (Q&T + I.H.) combines a quenched & tempered core (240–370 HB) with an induction-hardened surface (55–64 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 72-hour salt spray rating 9. Designed for the most demanding heavy-duty cylinders, it offers maximum core strength and extreme surface wear resistance. Full customization is supported.

The Chrome Plated C50 Rod (Induction Hardened) combines a non-hardened core with a high-hardness induction-hardened surface of 55–64 HRC, depth 0.5–3.5 mm. Available in φ6–300 mm and lengths up to 8000 mm, it meets ISO f7 tolerance and features an 850–1150 HV hard chrome finish with 72-hour salt spray rating 9. Its ultra-wear-resistant surface is ideal for heavy-duty hydraulic cylinders in severe environments. Full customization of dimensions, hardening depth, and surface treatments is supported.

The Chrome Plated C50 Rod (Quenched & Tempered) features a high-carbon steel core treated to 230–370 HB for superior strength and deformation resistance. 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 72-hour salt spray rating 9, it is ideal for heavy-duty, high-pressure hydraulic cylinders requiring maximum core strength and wear performance. Full customization of dimensions, heat treatment and surface finishing is supported.
