Import Alloy Steel Round Bar — Buy in wholesale FOB from Supplier in Taiwan

Power Vision supplies SCM440 (AISI 4140) chromium-molybdenum alloy steel round bar from Taiwan, with hot-rolled diameters from 50mm to 300mm and hot-forged diameters from 300mm to 900mm. This grade is a standardised medium-carbon alloy containing approximately 0.85-1.15% chromium and 0.15-0.25% molybdenum, delivering high fatigue strength, abrasion resistance, and toughness in the quenched and tempered condition. The stated diameter range covers both general engineering stock sizes and heavy-forged blanks for large shafting applications. JIS G4105 compliance is cited, with equivalent ASTM standards applicable for cross-reference to A193, A322, or A29 specifications.

The material is engineered for high-stress mechanical and structural service, with typical applications in automotive transmission shafts, axles, gears, and studs, plus oil and gas drilling equipment, hydraulic machinery rams, and heavy equipment pivot pins. SCM440 in the annealed condition machines readily with conventional high-speed or carbide tooling, though chip control and adequate coolant flow are important given the alloy's tendency to work-harden. Forged diameters above 300mm are typically supplied with generous machining allowance and proof-machined test pieces to verify internal soundness. The product is positioned as a staple in global industrial supply chains, indicating established export documentation and repeat-order reliability for fabrication workshops.

Buyers for this product category include tier-one automotive manufacturing subcontractors, oilfield services companies, industrial machinery rebuilders, and heavy equipment aftermarket parts producers. The source indicates flexible MOQ, though no specific tonnage or piece count is stated. Power Vision's location in Kaohsiung suggests shipment through one of Taiwan's major container ports, with established sea lanes to Southeast Asia, North America, and Europe. Response rate is recorded at 0.00 percent, so direct enquiry with full technical specifications is recommended to obtain accurate availability, current lead time, and pricing. Certification beyond the mentioned ISO standard should be requested explicitly if your project requires specific material test report formats.

Power Vision is based in Kaohsiung, Taiwan, a major industrial port city with established steel processing and maritime logistics infrastructure. The supplier is classified as imported tier with harbor trust level, indicating the profile derives from external data sources rather than direct platform engagement. Response rate is 0.00 percent with zero average response hours, so no inference about communication reliability can be drawn from platform metrics alone. The address in Kaohsiung 833 places the supplier within the southern Taiwan manufacturing belt, though no facility size, production equipment, or workforce details are disclosed in the available profile.

The company name 'Power Vision' does not indicate corporate structure, year of establishment, or capitalisation in the source data. No client list, export volume, revenue figure, or quality system certificate number is provided. The listing focuses on SCM440/AISI 4140 round bar as a core product, suggesting specialisation in this grade rather than broad alloy steel distribution. Buyers should independently verify whether Power Vision is a mill, a processor, or a trading company, as this distinction affects traceability, certificate authority, and recourse in case of material non-conformance. Direct site visit or third-party audit may be warranted for initial qualification given the absence of platform-mediated verification signals.
