Import Astm B348 Gr2 Titanium Bar And Rod — Buy in Bulk from Supplier in China

Astm b348 gr2 titanium bar and rod from Baoji Goodtrust Nonferrous Metals Co., Ltd. are round-section mill products conforming to ASTM B348, the standard specification for titanium and titanium alloy bars and billets. Grade 2 (UNS R50400) is commercially pure titanium with moderate strength and excellent formability, making it the most widely specified unalloyed grade for industrial applications. The supplier offers diameters from 3 mm to 300 mm and lengths from 50 mm to 6000 mm, with supply condition annealed and surface finish polished.

Manufacture proceeds via vacuum arc remelting of titanium sponge, followed by forging or rolling to final round section. The 100% free ultrasonic test per bar and spectrometer test stated by the supplier represent standard quality control for aerospace and medical-grade titanium, though buyers should confirm test sensitivity levels and acceptance criteria. Typical mechanical properties for Grade 2 in the annealed condition include 0.2% offset yield strength of 275 MPa minimum, tensile strength of 345 MPa minimum, and elongation of 20% minimum in 50 mm gauge length. The polished surface reduces oxide contamination during subsequent welding or machining operations.

Primary applications include chemical process equipment shafts, marine hardware, automotive exhaust components, architectural fasteners, and medical device preforms where weldability and moderate strength suffice over the higher strength-to-weight ratio of Ti-6Al-4V. The broad diameter range accommodates both precision-turned small components and large forged pressure vessel flanges. Buyers should confirm exact diameter tolerance (typically h9 or h11 for ground bar, per ISO 286-2), straightness requirements, and whether the supplier provides material certifications to EN 10204 3.1 or 3.2 format. Third-party test acceptance is stated but specific agencies and scope require clarification.

Baoji Goodtrust Nonferrous Metals Co., Ltd. operates from No.22 Tiacheng Road, Baoji 721000, Shaanxi Province, China, within the Baoji titanium industrial cluster. The supplier carries imported tier and harbor trust tier designations with no recorded response metrics, indicating buyers must proactively establish communication channels and response expectations. The company name 'Goodtrust' appears as a brand identifier on their product labels, with model numbering system GTM-1025 for this product line.

The listing discloses specific quality control measures (100% ultrasonic, spectrometer verification) and ISO 9001:2008 certification, though the certificate registration number and accreditation body are not provided. The stated acceptance of third-party testing and broad size capability (3-300 mm diameter) suggest production flexibility, but buyers should verify whether this range represents in-house capacity or includes subcontracted items with potentially different quality systems. No information is provided about foundry source, melting practice (single, double, or triple VAR), or in-house versus outsourced forging and rolling operations.
