The Chrome Plated AISI4130 Tube is a non-heat-treated hollow piston rod made from AISI 4130 Cr-Mo alloy steel seamless tube, offering higher strength and good 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 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 AISI4130 Rod features a QPQ-treated surface (diffusion zone 0.30–0.40 mm, white layer ≥25 µm) achieving ≥650 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 AISI 4130 Cr-Mo steel with excellent nitriding response, this chrome-free rod delivers exceptional wear and corrosion resistance for demanding hydraulic cylinders. Full customization supported.

The Chrome Plated AISI4130 Rod (Q&T + I.H.) combines a quenched & tempered core (260–330 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, ISO f7 tolerance, and 96-hour salt spray rating 9. Designed for heavy-duty hydraulic cylinders, it offers excellent core strength and surface wear resistance, with full customization supported.

The Chrome Plated AISI4130 Rod (Induction Hardened) combines a tough non-hardened core with an induction-hardened surface of 50–60 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 excellent wear resistance suits demanding hydraulic cylinders in construction, oil & gas, and aerospace applications. Full customization of dimensions, hardening depth, and surface treatments is supported.

The Chrome Plated AISI4130 Rod (Quenched & Tempered) features a Q&T treated chromium-molybdenum alloy steel core of 260–330 HB, delivering excellent strength and fatigue resistance. Available in φ6–300 mm, up to 8000 mm long, it meets ISO f7 tolerance with an 850–1150 HV hard chrome finish and 96-hour salt spray rating 9. Ideal for medium-to-high-pressure hydraulic cylinders, it supports full customization of dimensions, heat treatment and surface finishing.
