The product is High Hardenability Characteristic AISI O2 Steel, an oil‑hardening cold‑work tool steel identified by the standards AISI O2, DIN 1.2842 and JIS SKS31. It is supplied from Dongguan Songshun Mould Steel Co., Ltd., located at No.4 Dongda Street, Sha Tou Dongguan 523850, China. The alloy contains elevated levels of carbon, chromium and tungsten, which give it greater hardenability than the comparable O1 grade. The steel is offered as round or flat bars that can be cut to customer‑specified dimensions.
In the tool‑steel market the O2 grade typically achieves a hardness of 58‑62 HRC after oil‑quenching, providing superior wear resistance for cutting tools and dies. The presence of vanadium refines the grain structure, reducing overheating sensitivity and producing a uniform carbide distribution. Standard industry practice treats O2 steel as a low‑alloy tool steel, suitable for applications where high tensile strength and dimensional stability are required. Typical tolerances for bar dimensions are ±0.1 mm, and heat‑treatment specifications follow ISO 6507 for Rockwell hardness testing.
Buyers such as die‑makers, punch manufacturers and precision machining shops commonly source this steel for components that experience repeated impact. Dongguan Songshun can provide custom cutting, packaging on pallets, and trade terms such as FOB or CIF upon request. The exact MOQ, lead time and payment conditions are not listed and should be confirmed directly with the supplier. Requesting a mill test certificate will verify the chemical composition and mechanical properties before shipment.

Before ordering, request a mill test certificate that details the exact chemical composition and mechanical properties of the steel. Verify the supplier’s trade registration and confirm that the "harbor" trust tier aligns with your internal risk criteria. It is also prudent to ask for recent factory photographs or video tours to ensure production capacity matches your volume requirements.
Logistics for this product typically involve FOB or CIF terms from major Chinese ports such as Shenzhen or Shanghai. Lead times for custom‑cut bars are usually four to six weeks, but the precise schedule should be confirmed with the supplier. Payment terms often follow a 30 % T/T deposit with the balance payable against shipping documents, though you should negotiate terms that suit your cash‑flow policy.
Quality assurance should include a pre‑shipment inspection by a third‑party agency, focusing on hardness testing, dimensional verification and surface condition. Ensure that the supplier provides the test reports, a certificate of conformity and any applicable ISO or SGS documentation. Retaining a copy of the inspection report will support customs clearance and downstream quality control.
