1.2312 is a pre-hardened Cr-Mn-Mo alloy tool steel engineered for improved machinability through controlled sulfur addition (0.05-0.1%). Supplied by Shanghai Jiebao Metal Co., Ltd. from Shanghai, this grade arrives in a ready-to-machine condition at approximately 28-32 HRC (280-320 HB), eliminating the need for post-delivery heat treatment. The sulfur content is specifically calibrated to boost milling speeds by roughly 30% and drilling speeds by up to 300% compared to standard P20, making it a practical choice for high-volume mold shops where cycle time matters.
Available from Shanghai Jiebao in round bars (20-500 mm diameter), plates, and blocks (12-300 mm thickness, 200-2300 mm width), with stock plates in the 20-120 mm range held in pre-hardened condition. Surface options include black surface, roughly machined, or peeled and turned, depending on your finishing requirements. This steel is the sulfur-modified equivalent of ASTM P20+S and 40CrMnMoS8-6, widely specified for plastic injection molds, die casting dies, and tooling applications requiring stable dimensions and uniform hardness after machining.

Sourcing 1.2312 pre-hardened tool steel from Shanghai gives buyers access to one of China's most established metal supply hubs. Shanghai Jiebao Metal Co., Ltd. operates from Songjiang District, a region with a concentration of metals and machinery suppliers, which can simplify logistics for consolidated shipments. When importing, request full material test certificates and verify that the chemical composition and hardness match your specifications before confirming the order.
For international buyers, it is advisable to agree on inspection terms (such as third-party testing at the mill or at port) before shipment. Confirm packaging standards for heavy steel plates and bars to avoid transit damage, and clarify incoterms (FOB Shanghai, CIF, etc.) early in negotiations. Lead times for non-stock dimensions of 1.2312 steel may differ from in-stock plate sizes (20-120 mm), so factor this into your project timeline when placing orders with Shanghai Jiebao Metal.
