The Chrome Plated CK45 Tube is a non-heat-treated, hollow piston rod made from CK45 seamless steel tube. Available in OD φ25–300 mm and lengths up to 8000 mm, it features ISO f7 tolerance, a hard chrome layer of 850–1150 HV, and 96-hour salt spray rating 9. Ideal for weight-sensitive and fluid-passage hydraulic cylinders, it offers full customization of dimensions, wall thickness, heat treatment, and surface finishing for diverse industrial applications.

The Nitrocarburized CK45 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. This chrome-free, dimensionally stable rod provides excellent wear and corrosion resistance for hydraulic and general industrial cylinders, with full customization supported.

The Chrome Plated CK45 Rod (Q&T + I.H.) combines a quenched & tempered core (220–360 HB) with an induction-hardened surface (50–62 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 200-hour salt spray rating 9. Designed for extreme heavy-duty cylinders, it offers maximum core strength, surface wear resistance, and full customization.

The Chrome Plated CK45 Rod (Induction Hardened) features a non-hardened core with a high-hardness surface layer of 50–62 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 high-wear hydraulic cylinders, it offers full customization of dimensions, hardening depth, and surface treatments.

The Chrome Plated CK45 Rod (Quenched & Tempered) offers enhanced core strength and toughness, with a hardness of 220–360 HB. Sizes range from φ6–300 mm up to 8000 mm long, featuring f7 precision and a hard chrome layer of 850–1150 HV. It withstands 96-hour salt spray to rating 9. Ideal for medium-to-high-pressure hydraulic cylinders, it supports full customization of dimensions, heat treatment and surface finishing for demanding applications.

The Chrome Plated CK45 Rod is a cost-effective, non-heat-treated precision piston rod made from CK45 medium carbon steel. Available in diameters φ6–300 mm and lengths up to 8000 mm, it features tight straightness and f7/h7/h9 tolerance grades. The hard chrome layer (20–40 µm typical) reaches 850–1150 HV with excellent wear and corrosion resistance (96-hour salt spray rating 9). Ideal for standard hydraulic cylinders and general industrial applications, with full customization supported for dimensions, heat treatment, and surface finishing.
