Steel EN31/ 52100
Dongguan Songshun Mould Steel Co., Ltd. manufactures round bar made from high‑carbon chromium alloy steel EN31, equivalent to AISI 52100. The bars are supplied in diameters ranging from 20 mm to 800 mm and lengths between 3000 mm and 9000 mm. Each bar conforms to ISO‑based quality management standards and is intended for bearing and gear applications. The supplier’s catalogue lists a flexible minimum order quantity, to be confirmed directly.
EN31/52100 steel contains high carbon and chromium, delivering typical hardness values of 58 - 65 HRC after heat treatment and tensile strengths around 1900 - 2100 MPa. Standard heat‑treatment options include annealing, carburising and quenching, allowing buyers to tailor surface hardness. Dimensional tolerance is generally ±0.05 mm on diameter, and surface roughness is usually Ra 0.8 µm (typical). The material is recognised for excellent wear resistance and machinability in precision engineering.
The round bars are widely used by automotive, aerospace and heavy‑machinery manufacturers for bearings, shafts and high‑stress components. Orders are packaged in wooden pallets or steel drums and can be shipped under FOB or CIF incoterms as agreed. Prospective importers should confirm the exact grade, heat‑treatment state and request ISO certificates before finalising the contract.

Sourcing Steel EN31/ 52100 from Dongguan Songshun Mould Steel Co., Ltd. - China Import Guide
Importers should request the material test report showing carbon and chromium percentages, as well as the hardness profile after heat treatment, to ensure the EN31/52100 grade meets the design requirements. Verifying the ISO certification will also confirm the supplier’s quality system.
Typical shipping arrangements are FOB from the Port of Shenzhen or CIF to the buyer’s port, with lead times depending on order size and any heat‑treatment processing. Payment is commonly made by T/T against a pro‑forma invoice, but the exact terms should be negotiated.
A third‑party inspection before loading can verify dimensions, surface finish and hardness. Retaining the inspection certificate and the supplier’s test report will aid customs clearance and downstream quality control.
