Grades of Stainless Steel Square Bars

SS 304 Square Bars

  • General-purpose, austenitic stainless steel
  • Excellent corrosion resistance, great for food-grade and industrial applications

SS 316 Square Bars

  • Molybdenum-altered for even greater pitting resistance
  • Recommended for marine, chemical, and pharmaceutical industries

Alloy Steel & Carbon Steel Bars

  • High tensile strength, automotive and heavy engineering

Nickel Alloy & Duplex Bars

  • Heat-resistant, corrosion-proof, aerospace and offshore structures

Mild Steel Square Bars

  • Affordable, weldable — perfect for construction

Titanium Square Bars

  • Light as a feather, corrosion-resistant, for medical and aerospace

Square Bar Sizes, Finishes & Standards

Size Range Length Finish Types Standards
6mm – 150mm 3m to 6m Bright, Black, Cold Drawn ASTM A276 / A484
  • Tolerances available as per h11 / k12
