Stainless Steel Round 303 - 1-1/8 Inches

This 1-1/8" diameter 303 Stainless Steel Round Bar is a free-machining austenitic grade engineered for high-speed automated production. Conforming to ASTM A582, it delivers 90,000 PSI tensile strength, good corrosion resistance, and superior machinability for complex machined components. In stock Los Angeles.

  • 303 Stainless Steel Construction
  • ASTM A582 Certified
  • 90,000 PSI Tensile Strength
  • Excellent Machinability (Free-Machining)
Overview|Specifications|Applications|Finish Options|How to Measure|Order Checklist

This 1-1/8" 303 round bar is an austenitic stainless steel specifically designed for superior machinability. An addition of sulfur to its composition acts as a chip breaker, reducing tool wear and allowing for higher cutting speeds. It provides 90,000 PSI tensile strength, good corrosion resistance in mild environments, and conforms to ASTM A582. This grade cannot be hardened by heat treatment.

As a medium-diameter bar, this 1-1/8" size is highly versatile for creating shafts, axles, bushings, spacers, and various machined components. Its dimensional stability is ideal for CNC lathes and screw machines, enabling the efficient production of parts with tight tolerances for industrial and manufacturing sectors.

Specifications

  • Material: 303 Stainless Steel
  • Standards: ASTM A582
  • Strength/Tensile: 90,000 PSI
  • Dimensions: 1-1/8" Diameter x 144" Length
  • Finish: Cold Drawn, Annealed
  • Certifications: MTR Available

Applications

  • Automated Machining: Shafts and axles - medium diameter provides strength for rotating parts.
  • Fasteners & Hardware: Custom bolts and standoffs - easily threaded and machined to precise dimensions.
  • Valves & Fittings: Valve bodies and stems - good corrosion resistance for non-marine fluid control.
  • Industrial Equipment: Bushings and spacers - excellent machinability for high-volume production runs.

Target Users

Machinists, fabricators, and CNC operators rely on 303 Round Bar for its excellent chip control and smooth finish in industrial and automotive applications throughout the Los Angeles area.

Finish Options

This product comes standard with a cold drawn finish, providing tight dimensional tolerances and a smooth, bright surface. For specific project requirements, other finishes such as centerless ground for even tighter tolerances may be available via special order. Contact our Los Angeles sales team for custom finish inquiries.

How to Measure

Round bar is measured by its diameter - the distance across the circular cross-section. Use calipers or a micrometer for an accurate measurement.

Example: To order this bar, specify "303 Stainless Round Bar, 1-1/8 inch diameter".

Order Checklist

  • Product name and required dimensions (1-1/8" x 144")
  • Material specification and quantity
  • Confirm grade (303) meets requirements
  • Surface finish requirements (Cold Drawn)
  • Certifications required (Mill Test Report)
  • Special handling or delivery requirements
