The Chrome Plated ST52 Tube is a non-heat-treated hollow piston rod made from ST52 seamless steel tube, known for excellent weldability and balanced mechanical properties. 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 200-hour salt spray rating 9. Ideal for lightweight, fluid-passage or welded hydraulic cylinders, it offers full customization of dimensions, wall thickness, heat treatment and surface finishing.

The Nitrocarburized ST52 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 ST52 steel with excellent weldability, this chrome-free, dimensionally stable rod provides superior wear and corrosion resistance for welded hydraulic cylinders and outdoor equipment, with full customization supported.

The Chrome Plated ST52 Rod (Quenched & Tempered) combines ST52's excellent weldability with enhanced core strength through Q&T treatment, achieving 200–280 HB hardness. Available in φ6–300 mm diameters and lengths up to 8000 mm, it features ISO f7 tolerance and a hard chrome layer of 850–1150 HV. With 200-hour salt spray rating 9, it is ideal for medium-to-high-pressure welded hydraulic cylinders. Full customization of dimensions, heat treatment and surface finishing is supported.

The Chrome Plated ST52 Rod is a non-heat-treated precision piston rod made from ST52 carbon-manganese steel, known for its excellent weldability and balanced strength-toughness combination. Available in diameters φ6–300 mm and lengths up to 8000 mm, it features ISO f7 tolerance and a hard chrome layer of 850–1150 HV. With 96-hour salt spray rating 9, it is a cost-effective choice for medium-duty hydraulic cylinders, construction and agricultural machinery. Full customization of dimensions, heat treatment and surface finishing is supported.
