OD 6-300mm Super Austenitic Stainless Steel Bar

Product Description
654SMO (S32654, 1.4652) Stainless Steel Bar Bright Black Rod
Material Overview

UNS S32652 (654SMO) is a super austenitic stainless steel grade 1.4652 / X1CrNiMOCUN24-22-8, offering superior corrosion resistance compared to standard austenitic steels. This high-performance alloy contains 23% nickel, 25% chromium, and 7% molybdenum, making it suitable for demanding industrial applications.

Manufacturing Process

654SMO's high molybdenum content presents manufacturing challenges during seamless pipe perforation. Our specialized process involves center perforation of round steel followed by cold rolling or cold drawing, ensuring high success rates and quality consistency despite increased production costs.

Performance Advantages
  • Exceptional local corrosion resistance in seawater, aeration, and crevice conditions
  • Superior pitting and stress corrosion resistance
  • Excellent mechanical properties with high yield strength
  • Good processability and workability
  • Superior to 904L and 254SMO in high-temperature and corrosive environments
  • Cost-effective alternative to nickel-based alloys and titanium
Standards & Specifications
  • ASTM A312 - Seamless and Welded Austenitic Stainless Steel Pipe
  • ASTM A269 - Seamless and Welded Austenitic Stainless Steel Pipe for General Equipment
  • ASTM B673, B674, B677, B675, B676, B690

Welded Pipe/Tube: Gas tungsten arc welding, Plasma arc welding (PAW), Submerged arc welding (SAW)

Surface Finish
  • Annealed & pickled
  • Bright annealing
  • Polished
End Preparation
  • Beveled or plain end
  • Square cut, burr free
  • Plastic cap protection at both ends
Packaging Options
  • Bare packing
  • Bundle packing with woven bag
  • Wooden or steel frame crate packing
  • Plastic cap protection
  • Sea-worthy delivery protection
  • Custom packaging available
Quality Assurance & Testing
  • 100% PMI and Spectro Chemical Analysis for raw material
  • 100% Dimension & Visual Examination
  • Mechanical Properties Testing (Tension, Flaring, Flange, Hardness, Reversed Flattening)
  • 100% Hydrostatic Test or 100% NON-DESTRUCTIVE Test (ET or UT)
  • Radiographic Test for welded pipe
  • Optional Tests: Straightness, Roughness, Intergranular Corrosion, Impact, Grain Size Determination

All test and inspection results are documented in comprehensive reports according to standard specifications.
