Import 303 Stainless Steel Six Angles — Buy in wholesale FOB from Supplier in China

303 stainless steel six angles, or hexagonal bar, is a free-machining austenitic stainless steel shaped product supplied by Wuxi Hao Yao metal materials Co., Ltd. from Jiangsu Province, China. The grade contains deliberate sulfur and phosphorus additions that break chip formation during high-speed machining, a distinguishing feature from the more common 304 grade. Hexagonal profiles range from H2 to S55mm across flats, with round bar equivalents from 0.7mm to 300mm diameter available from the same supplier line. The material maintains the characteristic 18-8 chromium-nickel austenitic matrix, with sulfur levels typically 0.15% minimum to ensure machinability ratings superior to standard austenitic grades.

The sulfur and phosphorus content in 303 creates manganese sulfide inclusions that lubricate cutting tools and extend tool life, though this slightly reduces corrosion resistance compared to 304 and 316 grades. Typical applications demand environments where moderate corrosion resistance suffices, such as indoor industrial equipment, non-marine atmospheric exposure, or chemically mild process streams. Surface finishes include polished, ground, black (hot-rolled), wire-drawn, knurled, and decorative patterned finishes. The company notes capability for non-standard custom dimensions, indicating rolling mill flexibility for small-batch specialized orders. Mechanical properties typical for solution-annealed 303 include yield strength around 205 MPa, tensile strength 515-620 MPa, and elongation 40% minimum, though buyers should request mill test certificates for specific heat confirmation.

Buyers of 303 stainless hex bar span precision machining shops, fastener manufacturers, pump and valve component producers, and marine equipment fabricators requiring machined structural elements. The product ships with standard mill test certificates and export documentation for international trade. Packaging is not detailed in the source data; confirm protective wrapping and bundling specifications with Wuxi Hao Yao directly. Lead times, minimum order quantities, and specific Incoterms require direct supplier negotiation, as these transactional details are not stated in the available listing information.

Wuxi Hao Yao metal materials Co., Ltd. operates from Dongfang Steel City in Wuxi, Jiangsu Province, China, postal code 214000. The supplier maintains a harbor trust tier with a 0.00% response rate and zero recorded average response hours, which signals extremely limited engagement data rather than verified non-response. The listing presents a broad stainless steel long product portfolio spanning round bar, hexagonal bar, square bar, ground rod, half-round, oval bar, flat bar, and angle iron across multiple austenitic, martensitic, and precipitation-hardening grades including 316 series, 304 series, 309S, 310S, 321, 630, 631, 420, 430, 416, and carbon steels 1214, 1215, 45#, 1045, and A3.

The company emphasizes custom non-standard production capability and lists surface finishing options including polishing, grinding, black rod, wire drawing, knurling, and decorative patterning. Application markets cited span domestic appliances, kitchen equipment, food processing, medical devices, metal hose, shipping, computer and mobile phone components, machinery manufacturing, automotive parts, and construction. The source description frames a customer-oriented service philosophy but provides no verified production capacity, employee count, revenue figures, quality system certifications, or named client references. Buyers should independently verify mill compliance, export licensing, and quality management system registration before placing trial orders.
