Spring Steel Round Bar 55crmna
The Spring Steel Round Bar 55CrMnA offered by Wanfang Steel Group Co., Limited is a chromium‑manganese alloy steel bar designed for demanding industrial parts. It conforms to GB/T 1222 and is supplied hot‑rolled. Diameter options run from 16 mm up to 300 mm, and lengths can be cut to customer requirements.

Standard industry practice calls for chemical analysis and impact testing to verify compliance. Wanfang Steel’s production facilities are located in Shandong, China, and the company is classified as an imported‑tier supplier with a harbor‑level trust rating.
Typical buyers include automotive component manufacturers, heavy‑machinery fabricators and spring‑part producers who require material that resists deformation under cyclic loading. The supplier indicates flexible minimum order quantities and offers FOB or CIF shipping from Chinese ports, though exact terms should be confirmed directly. Prospective importers should request the mill test certificate and verify that the bar meets the required GB/T 1222 specifications before placing an order. Payment conditions and lead times are not disclosed in the listing and must be negotiated with Wanfang Steel.

Sourcing Spring Steel Round Bar 55CrMnA from Wanfang Steel Group Co., Limited - China Import Guide
Before placing an order, verify that the material conforms to GB/T 1222 and obtain the mill test certificate confirming chemical composition, tensile strength and hardness. Request a copy of the supplier’s business licence and any available quality‑system certificates to ensure the company’s credibility.
Shipping terms are typically offered as FOB or CIF from Chinese ports, but the exact incoterm, freight charges and payment schedule must be agreed with Wanfang Steel. Confirm whether the buyer or seller arranges inland transport and insurance, and negotiate payment methods such as T/T or LC based on mutual risk tolerance.
Quality control usually involves pre‑shipment inspection, dimensional checks and surface‑finish verification. Arrange for a third‑party inspection agency to audit the bar against the agreed specifications, and ensure that the supplier provides the test report, packing list and certificate of origin alongside the commercial invoice.
