SS304 Stainless Steel Fasteners

Premium Grade A2-70 (18/8 Chromium-Nickel) industrial fasteners, bolts, nuts, and washers.

SS304 Material Specifications

Grade 304 (equivalent to A2 stainless steel) is the standard and most versatile fastener alloy, offering excellent corrosion resistance under typical atmospheric conditions, water exposure, and mild chemical contact.

Composition Tensile Strength Yield Strength Hardness
18% Cr, 8% Ni 500-700 MPa 210 MPa (Min) 85 HRB (Max)

Applications & Inventory Range

SS304 fasteners are ideal for food processing machinery, kitchen equipment, architectural panels, fresh-water plumbing, automotive trim, and general sheet metal fabrication.

SS316 Marine Grade Fasteners

Premium Grade A4-70 (Molybdenum-alloyed) fasteners for extreme acid and chloride resistance.

SS316 Molybdenum Advantage

Grade 316 (equivalent to A4 stainless steel) contains 2-3% Molybdenum. This chemical inclusion increases resistance to localized pitting corrosion and stress cracking in marine, saline, and highly acidic industrial environments.

Composition Tensile Strength Yield Strength Corrosion Rating
16% Cr, 10% Ni, 2% Mo 500-750 MPa 210 MPa (Min) Superior (Chloride/Acid)

Crucial for Chemical & Marine Industries

SS316 fasteners are widely utilized in pharmaceutical packaging, coastal constructions, marine vessels and shipyards, wastewater treatment plants, and petrochemical engineering pipelines.

  • ⚓ SS316 Heavy Hex Anchor Bolts: Structural foundations (A4-70/A4-80)
  • ⚓ SS316 Self-Tapping Screws: High-resistance sheet metal fastening
  • ⚓ SS316 Double-End Studs: Flange coupling joints (DIN 2510)
  • ⚓ Quality Compliance: Supplied with certified Material Test Certificates (MTC)

SS304 vs SS316 Fasteners: What is the Difference?

A comprehensive engineering comparison guide for selecting industrial fastener alloys.

1. Chemical Composition Analysis

The fundamental difference between SS304 and SS316 lies in their chemical makeup. While both are chromium-nickel alloys, their corrosion-resistance capabilities differ due to the presence of a key element: Molybdenum.

  • Grade 304 (A2 Stainless): Contains approximately 18% Chromium and 8% Nickel. It offers excellent general-purpose corrosion protection under typical atmospheric conditions.
  • Grade 316 (A4 Stainless): Contains approximately 16% Chromium, 10% Nickel, and 2-3% Molybdenum. The addition of molybdenum is the primary differentiator, giving the alloy superior resistance to chloride-induced pitting, stress cracking, and industrial acids.

2. Mechanical Properties Breakdown

Both grades share similar mechanical properties, particularly tensile strength when cold worked to class 70 specifications (A2-70 or A4-70).

Property SS304 (A2-70) SS316 (A4-70)
Chromium (Cr) % 18.0 - 20.0% 16.0 - 18.0%
Nickel (Ni) % 8.0 - 10.5% 10.0 - 14.0%
Molybdenum (Mo) % None 2.0 - 3.0%
Tensile Strength (MPa) 500 - 700 500 - 750
Pitting Resistance (PREN) ~18 ~23 (Superior)

3. Practical Application Guidelines

Choose Grade SS304 (A2) for:

  • General factory manufacturing machines and assemblies.
  • Kitchen hardware and food processing structures.
  • Architectural framing and light poles.

Choose Grade SS316 (A4) for:

  • Marine applications, offshore installations, and coastal structures.
  • Chemical production lines and acid treatment machinery.
  • Pharmaceutical preparation equipment.
