Product Applications

  • Round Bars

    General-purpose choice for shafts, pins, and fasteners. Bright-drawn rounds ensure dimensional accuracy for precision machining, while hot-rolled rounds are ideal for further processing.

  • Hex Bars

    Across-flats 4–50 mm, widely used for fasteners, valves, and precision parts. 316L hex bars can be electropolished to meet strict medical and marine requirements.

  • Square Bars

    10–100 mm square stainless steel bars serve structural applications, fixtures, and OEM parts. Duplex 2205 square bars provide higher yield strength and excellent resistance to chloride pitting.

Services & Processing

  • Cut-to-size: Saw cutting, chamfering, deburring.
  • Heat Treatment: Annealing, solution treatment, quenching & tempering, PH aging.
  • Surface Finishes: Bright draw, polished, electropolished, passivated.
  • Testing & Reports: Chemistry and mechanical data, ultrasonic inspection, salt-spray testing, ASTM A262 IGC.

Applications of Stainless Steel Bars

FAQs

Which stainless steel bars are best for marine or chloride environments?
316L and duplex 2205 provide strong resistance; 904L is ideal for acids.
Can bars be cut to custom length?
Yes. Standard tolerance is ±3–5 mm, tighter on request for small diameters.
What surface finishes are available?
Hot-rolled black, cold-drawn bright, polished Ra≤0.8 μm, passivated, and electropolished.
Do you provide certificates?
Each order includes an MTC and ISO 9001 compliance; third-party inspections are available.
What's the difference between 410 and 420J2 bars?
410 offers good machinability with moderate hardness; 420J2 reaches HRC 50–55 for cutting tools and wear parts.
