Import A2 Mould Steel 1.2363 Tool Steel Sheets — Buy in wholesale FOB from Supplier in China

A2 Mould Steel 1.2363 Tool Steel Sheets from Dongguan Songshun Mould Steel Co., Ltd. are air-hardening cold work tool steel supplied in flat sheet form, designated under the European grade X100CrMoV5. This material contains approximately 0.95-1.05% carbon, 4.80-5.50% chromium, 1.20-1.50% molybdenum, and 0.15-0.35% vanadium, giving it a balanced combination of wear resistance and toughness after proper heat treatment. The sheets are typically supplied in the annealed condition with a hardness of approximately 207-241 HB, ready for machining before final hardening to 58-62 HRC. Standard sheet thicknesses range from 10mm to 150mm, with widths and lengths cut to customer requirements from mill stock.

The 1.2363 grade belongs to the cold work tool steel family that hardens in air or controlled atmosphere, minimising distortion compared to oil-hardening grades. Its metallurgical design prioritises carbide volume for abrasion resistance while retaining sufficient matrix toughness to resist cracking in interrupted cutting or punching operations. Typical delivery condition is soft-annealed to spheroidised carbide structure, enabling complex machining before the final austenitising, quenching, and multiple tempering cycles. Surface condition is usually black/scaled or ground, depending on thickness and customer specification. The grade conforms to DIN EN ISO 4957 and finds equivalents in AISI A2 and JIS SKD12 classifications.

Buyers of this steel include tool rooms, die-making shops, automotive stamping operations, and precision engineering firms that manufacture blanking dies, forming dies, punches, gauges, and trimming tools. The material suits medium to high production volume applications where tool life between regrinds determines manufacturing economics. Sourcing from Dongguan Songshun involves confirming sheet dimensions, surface finish, and whether mill test certificates with chemical composition and hardness verification are provided. Heat treatment guidance, dimensional tolerances to ISO 18286 for tool steel plate, and any edge preparation requirements should be clarified before order confirmation.

Dongguan Songshun Mould Steel Co., Ltd. is based at No.4 Dongda Street, Sha Tou, Dongguan 523850, in Guangdong Province, China. The company operates as an imported-tier supplier within the platform classification, indicating it sources or trades material rather than manufacturing primary steel. Its trust tier is rated harbour, and both response rate and average response time show zero recorded activity, meaning buyers should expect to initiate contact and allow time for reply. No verification of factory ownership, export licence, or quality management certification is stated in the available profile data.

#/company

The listing presents A2 Mould Steel 1.2363 Tool Steel Sheets without specifying mill origin, stockholding capacity, or processing capabilities such as sawing, grinding, or heat treatment services. Buyers should verify whether Dongguan Songshun holds inventory locally in Dongguan or brokers mill-direct shipments, what documentation accompanies delivery (mill certificates, third-party inspection reports), and whether the company offers cut-to-size processing or delivers only full sheets. The absence of stated client references, annual turnover, or years in operation means due diligence on business registration and trade history becomes essential before committing to volume orders.
