Stainless Steel Bar - 304/316 Grade, Round/Square/Flat, ASTM A276 Certified

Technical Specifications of Stainless Steel Bar

Stainless Steel Bar - 304/316 Grade, Round/Square/Flat, ASTM A276 Certified

Stainless steel bar represents a fundamental structural component in modern manufacturing, offering exceptional mechanical properties and corrosion resistance across diverse industrial applications. These precision-engineered bars serve critical roles in construction, automotive, aerospace, and chemical processing industries where material integrity and long-term durability are non-negotiable requirements. Available in multiple grades and profiles, stainless steel bars provide engineers and fabricators with versatile solutions for components ranging from precision shafts to architectural support structures.

What is Stainless Steel Bar?

A stainless steel bar is a solid metal product manufactured through hot rolling or cold drawing processes, characterized by its chromium content of minimum 10.5% which forms a passive oxide layer preventing corrosion. These bars are produced in various cross-sectional geometries including round, square, hexagonal, and flat configurations, with dimensional tolerances conforming to ASTM A276/A276M standards for precision applications requiring strict diameter and straightness specifications.

Stainless Steel Bar Technical Specifications

Our stainless steel bars comply with ASTM A276/A276M-17 Section 6 for chemical composition and mechanical properties. Grade 304 bars exhibit tensile strength of 515 MPa minimum with 205 MPa yield strength, while 316L variants provide enhanced corrosion resistance through 2-3% molybdenum addition. Diameter range spans 6mm to 300mm for round bars, with length options up to 6 meters. Surface finishes include hot rolled, cold drawn, centerless ground, and polished conditions meeting Ra 0.8μm specifications per customer requirements.

Frequently Asked Questions

What is the minimum order quantity (MOQ)?

Our standard MOQ is 500 kilograms per specification, though we accommodate smaller quantities for premium grades or specialized profiles with adjusted pricing. Mixed-grade orders are accepted when total weight exceeds 1000 kilograms, allowing procurement flexibility for diverse project requirements.

Do you provide material test certificates?

Yes, we supply EN 10204 3.1 mill test certificates with every shipment, documenting chemical composition analysis, mechanical property test results, and heat treatment parameters. Additional third-party inspection certificates per ASTM A276 Supplementary Requirement S5 are available upon request for critical applications requiring independent verification.

What is the typical delivery time?

Stock items ship within 3-5 business days from order confirmation. Custom sizes requiring mill production follow 15-21 day lead times depending on specification complexity and current production schedules. Expedited processing is available for urgent requirements with 48-hour emergency service for select dimensions.

Can you cut to custom sizes?

Our precision cutting services accommodate tolerances of ±0.5mm for lengths up to 6 meters using CNC sawing equipment. We offer additional machining capabilities including centerless grinding, turning, and surface finishing to meet exact dimensional requirements. Custom profiles and non-standard cross-sections are produced through collaboration with specialized rolling mills for quantities exceeding 5000 kilograms.
