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

A2/1.2363 Tool Steel from Huangshi Better International Trade Co., Ltd is an air-hardening cold work tool steel conforming to AISI A2 and DIN 1.2363 (EN X37CrMoV5-1) specifications, characterised by a 5% chromium content that delivers balanced wear resistance and toughness. The material achieves hardness up to 60-62 HRC after appropriate heat treatment, with the supplier noting excellent dimensional stability during hardening, a critical property for precision tooling applications. Chromium provides moderate corrosion resistance and deep-hardening capability, while molybdenum and vanadium contribute to carbide formation and secondary hardening during tempering. The steel is supplied in standard mill forms including round bars, flat bars, and plates, with custom dimensions available subject to mill capacity and minimum order requirements.

The chemical composition of A2/1.2363 follows established industry norms: approximately 0.95-1.05% carbon, 4.80-5.50% chromium, 0.90-1.20% molybdenum, and 0.25-0.35% vanadium, with balance iron and controlled impurities. This alloy design prioritises air-hardening response, meaning full hardness is achieved with slower cooling rates than oil-hardening grades, reducing distortion risk in complex geometries. Typical annealed hardness is 200-250 HB, permitting conventional machining before heat treatment. The material exhibits good grindability relative to higher-vanadium tool steels, though users should verify specific surface finish requirements for fine-blanking and precision punching applications. Compared to D2 tool steel, A2 offers superior toughness with somewhat lower abrasion resistance, making it preferable for tools subject to impact or shock loading.

Primary applications include blanking and piercing dies, forming rolls, shear blades, and cold-heading tooling where a balance of wear life and structural integrity is essential. The automotive and general manufacturing sectors represent the largest demand segments, with particular utility in medium-run stamping operations and press tooling. Huangshi Better International Trade Co., Ltd sources this material from mills in the Hubei province region, leveraging proximity to major Chinese special steel producers. Buyers should confirm heat treatment condition as-supplied (annealed, pre-hardened, or quenched and tempered), exact dimensional tolerances per ISO 4957 or equivalent, and any ultrasonic testing certification. Payment terms, minimum order quantities, and lead times are not specified in the source data and require direct negotiation with the supplier.

Huangshi Better International Trade Co., Ltd is headquartered in Huangshi, Hubei Province, China, with postal code 435000, placing it within one of China's established industrial corridors with access to Yangtze River logistics and Wuhan's steel distribution networks. The company operates under a 'harbor' trust tier with a 0.00% response rate and zero recorded average response hours in the available data, indicating limited or untracked communication history through the platform. No information about company founding year, employee count, annual turnover, or manufacturing versus pure trading status is provided in the source profile. The supplier's business scope appears focused on international trade of special steels rather than primary mill production.

The listing emphasises export-ready tool steel with consistent hardenability and machinability for high-volume tooling production, suggesting Huangshi Better positions itself as a sourcing intermediary or distributor with mill relationships rather than an integrated manufacturer. The supplier's custom specification text demonstrates technical familiarity with A2 grade applications, referencing specific tooling types and performance requirements. No client references, project case studies, or domestic Chinese certifications such as GB standards are disclosed. Buyers should conduct independent due diligence including business licence verification through the Hubei Provincial Administration for Market Regulation, and request mill test certificates with full chemical analysis and mechanical property data traceable to the producing steelworks.
