High Strength Stainless Steel A325 Structural Bolts For Heavy Structure

Product Overview

Our High-Strength Stainless Steel A325 Structural Bolts are engineered for heavy-load structural applications demanding both extreme tensile strength and corrosion resistance. Combining the mechanical properties of ASTM A325 with the durability of stainless steel, these bolts are ideal for bridges, skyscrapers, offshore platforms, and industrial facilities where harsh environments and structural integrity are critical.

Key Features

✅ A325 Equivalent Strength in Stainless Steel

Tensile Strength: 120 ksi (830 MPa) minimum, matching ASTM A325 performance.
Material: Custom-forged 316 (A4) or 304 (A2) stainless steel, heat-treated for high strength.

✅ Corrosion Resistance

Marine-Grade Durability: 316 stainless steel withstands saltwater, chlorides, and industrial chemicals.
Passivated Finish: Enhanced oxide layer for long-term protection against oxidation and pitting.

✅ Structural Compliance

ASTM F593 (Stainless Steel Bolts) / AISC 360 / RCSC Specifications compliant.
Certified Traceability: Mill Test Reports (MTRs) provided for material and mechanical properties.

✅ Heavy-Duty Design

Full Thread or Partial Thread: ASTM-compliant thread lengths for shear or tension connections.
Hot-Dip Galvanized Nuts (Optional): Pair with ASTM A563 DH or Grade 8 nuts for galvanic compatibility.
