Kangtao 316 stainless steel bar is a molybdenum-alloyed austenitic round rod engineered for superior corrosion resistance, high mechanical strength, and long-term durability in demanding industrial environments. Compliant with ASTM A479, ASTM A276, and GB/T 1220 standards, this round rod is purpose-built for precision manufacturing and heavy-duty construction applications, delivering reliable performance under high stress, chloride exposure, and extreme temperatures. As a trusted B2B stainless steel supplier, Kangtao Steel provides full custom capabilities, strict quality control, and on-time global delivery to support your production and project needs.
Enriched with 2.0–3.0% molybdenum, our 316 stainless steel round rod delivers exceptional resistance to pitting, crevice corrosion, and chloride attack, outperforming standard 304 grades in marine, chemical, and coastal environments.
With tensile strength ≥515 MPa and yield strength ≥205 MPa, this round rod maintains excellent mechanical properties at both room and elevated temperatures, ideal for load-bearing structural parts and high-wear components.
All products are manufactured to meet ASTM, JIS, EN, and GB standards, with ISO 9001, SGS, and Intertek certifications. Third-party inspections (BV, TÜV) are supported for full quality transparency.
Cold-finished and hot-rolled options with tight tolerance control (h8–h11) ensure consistent diameters, straightness, and surface quality, reducing your secondary processing costs and improving assembly efficiency.
Standard sizes are in stock for 7-day quick delivery, while custom diameters, lengths, and surface finishes are available to match your unique project specifications.
