The O2 1.2842 mould hot rolled steel round bar supplied by Dongguan Songshun Mould Steel Co., Ltd. is an alloy tool steel designated as O2, 1.2842, SKS31 or 9Mn2V. It is a manganese‑vanadium alloy intended for cold‑work and mould applications and is hot rolled to diameters ranging from 10 mm to 600 mm. The steel conforms to AISI, ASTM, BS, DIN, GB and JIS standards, matching equivalents such as DIN 1.2842 and JIS SKS31. The product is offered in forged or hot‑rolled condition with surface options of black, peeled, polished or machined.
In the tool‑steel market the O2 grade typically contains 0.90‑1.05 % carbon, 1.0‑1.5 % manganese and 0.15‑0.25 % vanadium, delivering a hardness of 60‑62 HRC after quenching and tempering. Standard practice applies an annealing step followed by a Q+T heat treatment to achieve dimensional stability. Typical tolerances on the round bar diameter are ±0.1 mm for sizes up to 100 mm and ±0.2 mm for larger sections. The alloy’s wear resistance and toughness make it a standard choice for dies, punches and mould components.
Manufacturers of precision dies, extrusion punches and mould components in automotive, aerospace and general engineering sectors commonly source this steel. Dongguan Songshun offers bulk supply for international trade, provides free sample kits and maintains a 24‑hour online response capability. Buyers should confirm the required heat‑treatment condition, surface finish and certification (ISO or mill certificate) before placing an order. Trade can be arranged under common Incoterms such as FOB or CIF, with payment terms negotiable after verification of the supplier’s credentials.
