AISI O1 steel, also designated as DIN 1.2510 and JIS SKS3, is an oil-hardening cold work tool steel supplied by Dongguan Songshun Mould Steel Co., Ltd. in round bar, sheet, and plate forms. The alloy’s high carbon, manganese, chromium, and tungsten content delivers superior hardness and wear resistance, making it ideal for precision tooling applications. After oil quenching, the material typically reaches a hardness of 62 HRC, eliminating the need for water quenching and reducing the risk of cracking.
The chemical composition of O1 steel includes approximately 0.90% carbon, 1.00% manganese, 0.50% chromium, and 0.50% tungsten, with trace amounts of silicon, phosphorus, and sulfur. This composition enhances its hardening ability and dimensional stability, which is critical for tools subjected to high stress and abrasion. Standard forms include round bars with diameters ranging from 5 mm to 500 mm, sheets, and plates, all of which can be customized to specific dimensions using the supplier’s in-house cutting and processing equipment.
O1 tool steel is widely used in the manufacturing of punches, dies, gauges, slitting cutters, and knife blades, particularly for short-run tooling in cold forming and blanking operations. Buyers in the precision tooling, automotive, and aerospace industries favor this material for its balance of toughness and wear resistance. Dongguan Songshun Mould Steel Co., Ltd. maintains a large stock of over 20,000 tons and offers competitive pricing, making it a reliable source for bulk and custom orders.

Before sourcing AISI O1 steel from Dongguan Songshun Mould Steel Co., Ltd., verify the material’s chemical composition and hardness to ensure it aligns with your tooling specifications. Request documentation such as mill test certificates (MTCs) and heat treatment records to confirm the steel meets AISI or DIN 1.2510 standards. Additionally, check the supplier’s ability to provide custom dimensions and finishes, as these may impact the material’s performance in your application.
Clarify logistics details such as lead time, packaging, and Incoterms (e.g., FOB, CIF) with the supplier, as these are not specified in the listing. For bulk orders, discuss packaging options like wooden crates or bundles to prevent damage during transit. Confirm whether the supplier offers staggered deliveries to accommodate your production schedule and storage limitations.
Conduct quality checks by performing hardness tests using a Rockwell or Brinell tester, dimensional inspections with calipers or micrometers, and visual examinations for surface defects. Request third-party inspection reports or arrange for an independent surveyor to validate the material’s condition before shipment. For critical applications, consider additional testing such as ultrasonic or magnetic particle inspection to detect internal flaws.
