Import Astm1.2311plastic Mould Steel — Buy in Bulk from Supplier in China

ASTM 1.2311 is a pre-hardened plastic mould steel supplied by OTAI Special Steel Co., Ltd. in China, offered in a thickness range of 12 to 600 mm to suit diverse tooling requirements. The material is delivered in a ready-to-machine condition, eliminating the need for post-treatment hardening in many applications. Its alloy composition is engineered to balance toughness and wear resistance, critical for molds subjected to cyclic loading and abrasion during injection or compression molding operations.

The steel conforms to AISI, BS and GB standards, ensuring dimensional stability and consistent mechanical properties across batches. Industry practice for this grade includes a typical hardness of 280 to 320 HB in the pre-hardened state, with a standard carbon content of approximately 0.35 to 0.45 percent and chromium around 1.8 to 2.1 percent. Machinability is a defining feature, with standard cutting speeds comparable to low-alloy steels, while its polished surface finish meets the requirements of optical and precision components.

This grade is widely adopted in automotive interior trim, consumer electronics housings and medical device components where intricate geometries and tight tolerances are required. Importers typically source it in flat-rolled plates or blocks, with packaging tailored to prevent deformation during transit. Common trade terms include FOB or CIF, with MOQ and lead times confirmed directly with OTAI Special Steel Co., Ltd. for project-specific needs.

OTAI Special Steel Co., Ltd. operates from Dongguan City in Guangdong Province, China, with its registered address at 3#, Xiansha, Gaobu Town. The company is classified as an imported-tier supplier, indicating a focus on materials sourced or processed to international specifications. Its profile does not list a response rate or average response time, so direct contact is advised to confirm availability and technical support.

The supplier’s description highlights compliance with multiple standards and mentions certifications such as ISO and SGS, though these are not explicitly verified in the provided data. OTAI Special Steel Co., Ltd. positions itself as a provider of specialty steels for tooling applications, with a stated emphasis on consistency and reliability in material properties. Buyers should verify certification status and quality control processes directly with the supplier.
