Bulk Tool Steel Supply With Full QC and Traceability
We supply tool steel round bars, flat bars, plates, and forged blocks in annealed or agreed condition to distributors, stockists, importers, and manufacturers worldwide, with every order backed by MTC, heat number traceability, and pre-shipment inspection.
Who we are. Aobo Steel began in 2003 as a tool steel forging and processing operation in Huangshi, China. In 2017 we established Aobo Steel for international supply, and today we focus on sourcing, quality control, and export, backed by the full mill and supply-chain network built over two decades. We currently serve buyers across the Czech Republic, Brazil, the Philippines, India, and other markets.
Tool Steel Grades, Forms, and Delivery Condition
Our scope covers cold work, hot work, shock-resisting, plastic mold, bearing, and high-speed tool steels, supplied as raw material for machining, stocking, resale, and later heat treatment. Rings and discs are individually forged to near-net shape, not cut from bar or plate, giving continuous grain flow and stronger performance for high-load tooling.
