Technical Specifications of 316 Stainless Steel Bar

316 Stainless Steel Bar - ASTM A276/A484 Round, Flat, Hex Shapes

316 stainless steel bar represents a molybdenum-bearing austenitic grade that delivers exceptional corrosion resistance in chloride environments and elevated temperature applications. This premium-grade material serves critical roles in marine engineering, chemical processing, pharmaceutical equipment, and food production facilities where conventional austenitic grades prove inadequate. Manufactured to stringent ASTM A276 and A484 specifications, our 316 bars are available in round, flat, hexagonal, and square profiles with precise dimensional tolerances and certified chemical composition.

What is 316 Stainless Steel Bar?

316 stainless steel bar is an austenitic chromium-nickel-molybdenum alloy containing 16-18% chromium, 10-14% nickel, and 2-3% molybdenum per ASTM A240 chemical requirements. The molybdenum addition significantly enhances resistance to pitting and crevice corrosion in chloride-containing environments, while maintaining excellent formability and weldability characteristics. This grade exhibits a minimum tensile strength of 515 MPa and yield strength of 205 MPa in annealed condition, with density of 8.00 g/cm³ at 20°C.

316 Stainless Steel Bar Technical Specifications

Our 316 bars comply with ASTM A276/A276M-17 for hot-finished and cold-finished bars and ASTM A484/A484M-18 for general requirements. Chemical composition meets Section 6 requirements with carbon content limited to 0.08% maximum, ensuring optimal weldability without carbide precipitation. Available surface finishes include hot-rolled, cold-drawn, centerless ground, and precision-turned conditions with surface roughness Ra values ranging from 3.2 to 12.5 micrometers depending on finish specification.

Why Choose Our 316 Stainless Steel Bars

We maintain extensive inventory of 316 bars in diameters from 6mm to 300mm for round sections, and thickness ranges of 10mm to 100mm for flat bars. All material ships with EN 10204 Type 3.1 mill test certificates documenting chemical analysis, mechanical properties, and heat treatment records. Our manufacturing facility holds ISO 9001:2015 certification and operates advanced spectroscopic testing equipment to verify composition compliance prior to shipment. Mill-direct pricing structures provide cost-effective solutions for both prototype quantities and production volumes.

Frequently Asked Questions

What is the minimum order quantity (MOQ)?

Our standard MOQ is 500 kilograms for stock sizes in round, flat, and hex configurations. Custom profiles and non-standard dimensions require 1,000 kilogram minimum orders. We accommodate smaller quantities for sampling purposes at premium pricing, with orders processed within 3-5 business days for in-stock materials.

Do you provide material test certificates?

Yes, all shipments include EN 10204 Type 3.1 mill certificates issued by our ASTM-approved testing laboratory. Certificates document chemical composition via optical emission spectrometry, tensile testing results per ASTM E8, and hardness verification. Third-party inspection services from SGS, TÜV, or Bureau Veritas can be arranged at customer request with 5-7 day lead time extension.

What is the typical delivery time?

Stock sizes in standard lengths ship within 7-10 business days from order confirmation for domestic deliveries. Custom cutting, precision machining, or special surface treatments extend lead times to 15-20 business days. International shipments require additional 10-15 days for documentation processing and freight consolidation, with FOB, CIF, and DDP Incoterms available.

Can you cut to custom sizes?

Our precision cutting services accommodate tolerances of ±0.5mm for lengths and ±0.1mm for diameter specifications using advanced bandsaw and CNC turning equipment. We provide cut-to-length services for bars up to 6 meters, chamfering and deburring operations, and surface grinding to achieve Ra 1.6 micrometers finish. Custom machining includes threading, drilling, and milling operations with engineering drawing review prior to production.
