Buy & Import Custom Sus420 Wafer Ring from Donghongxin - Wholesale Supply

The product is a custom‑made SUS420 stainless‑steel wafer ring supplied by Donghongxin in Shenzhen, China. The ring’s thickness is not fixed; it is calculated from the depth of the film tray of the buyer’s equipment. The supplier requires the buyer to provide that depth so that the appropriate ring thickness can be machined. The material grade SUS420 is a martensitic stainless steel commonly used for wear‑resistant components.

In the metal‑working sector SUS420 rings are usually heat‑treated to achieve a hardness between 45 and 55 HRC. Typical tensile strength after treatment lies in the 450‑650 MPa range. Surface finishes such as ground or polished are offered with dimensional tolerances of ±0.05 mm. Standard inner diameters run from 10 mm to 200 mm and outer diameters from 20 mm to 400 mm, allowing the part to fit a wide variety of machines.

The rings are used in semiconductor equipment, precision optics holders and other automation fixtures that require a reliable, corrosion‑resistant interface. Buyers are typically OEMs or contract manufacturers who need a bespoke size and may order in low to medium volumes. Donghongxin does not list a minimum order quantity or lead time, so the importer should request those details directly. Payment and incoterm terms are negotiated per transaction, and the supplier’s “harbor” verification indicates a basic level of platform trust.

Frequently Asked Questions About Custom Sus420 Wafer Ring from Donghongxin
The ring is fabricated from SUS420 stainless steel, a martensitic grade that offers good wear resistance and moderate corrosion resistance.

Sourcing Custom Sus420 Wafer Ring from Donghongxin - China Import Guide

Before placing an order with Donghongxin, verify that the material grade, SUS420, meets your project specifications by requesting a mill test certificate or a recent hardness report. Confirm the exact depth of the film‑tray of your equipment, as this value defines the custom thickness of the wafer ring. Ask the supplier to provide a detailed drawing or CAD file of the proposed ring to avoid dimensional misunderstandings.

Discuss the preferred shipping terms early; most Chinese manufacturers quote FOB Shenzhen, but you may negotiate CIF or EXW depending on your logistics network. Clarify the payment schedule, such as a 30 % advance by telegraphic transfer followed by the balance against documents. Because the supplier’s response rate is currently zero, ensure you have an alternative communication channel, for example a direct email or phone line, before finalising the contract.

Arrange for a third‑party inspection either before shipment or at the loading port to confirm dimensional tolerance, surface finish and hardness. Request that Donghongxin supply a final inspection report and a certificate of conformity that references the agreed specifications. If you require additional testing, such as corrosion resistance or fatigue life, include those requirements in the purchase agreement so the supplier can schedule the appropriate laboratory analyses.
