Hard Chrome Plated Around Bar
The hard chrome plated around bar offered by Wuxi Hengtong Petrolic Machinery Co., Ltd. is a precision‑ground carbon‑steel bar that receives a 20‑30 µm chrome plating. The plating delivers a surface roughness of Ra 0.2 µm and the bar diameter conforms to ISO f7 tolerance, with ovality limited to half of that tolerance. Straightness is controlled to 0.2 mm per metre and the surface hardness lies between 850 HV and 1150 HV (Vickers 100 g). The bar passes a thermal‑shock test at 300 °C followed by water quench without cracking or delamination.
In the metal‑working industry, such hard‑chrome bars are classified as wear‑resistant precision components, typically produced from carbon‑steel grades containing 0.2‑0.5 % carbon and 0.8‑1.2 % chromium. Standard practice calls for ISO f6‑f8 diameter tolerance and surface finish around Ra 0.2 µm, matching the supplier’s specifications. The coating thickness of 20‑30 µm provides corrosion protection comparable to the typical 15‑35 µm range used in hydraulic cylinder rods. Buyers often verify porosity and corrosion ratings according to ISO 4540, where the listed bar scores 8‑10 for porosity and 7‑10 for salt‑spray resistance.
These bars are commonly sourced for hydraulic cylinders, shock absorbers and textile‑machine spindles, making them attractive to automotive OEMs, heavy‑equipment manufacturers and industrial equipment assemblers. The supplier ships each rod with an anti‑rust oil coating and a paper sleeve, suitable for bulk handling. Trade inquiries should confirm the minimum order quantity, packaging details and the preferred Incoterm such as FOB or CIF, as these are not disclosed in the listing. Potential buyers are advised to request test certificates for hardness, coating thickness and corrosion performance before finalising purchase.

Sourcing Hard Chrome Plated Around Bar from Wuxi Hengtong Petrolic Machinery Co., Ltd. - China Import Guide
Before confirming a purchase, importers should obtain the supplier’s test certificates for chrome thickness, surface hardness and corrosion rating, and compare them with the listed values of 20‑30 µm, 850‑1150 HV and ISO 4540 rating 7‑10. Request a dimensional inspection report confirming ISO f7 tolerance and straightness of 0.2 mm/m. Verifying the anti‑rust oil application and paper‑sleeve packaging will also prevent damage during transport.
The supplier mentions shipment in bulk with each rod coated in anti‑rust oil and enclosed in a paper sleeve. Buyers need to agree on an Incoterm such as FOB Wuxi port or CIF Shanghai, and clarify the expected lead time, which is not disclosed in the listing. Payment terms should be negotiated and documented, typically via T/T or LC, before the goods are dispatched.
On arrival, a third‑party inspection can verify coating integrity, hardness and dimensional compliance using portable Vickers testers and calibrated micrometers. Request the original ISO 1456/1458 porosity report and the ASTM B117 salt‑spray certificate to ensure the bar meets the advertised ratings. Proper documentation, including a mill test report and packing list, will streamline customs clearance.
