Why Metal Chemistry Matters: 

Stainless steel hooks failing within 5 years? Most contain sulfur levels up to 0.03% - creating microscopic corrosion sites when exposed to:  
- Coastal salt spray  
- Industrial pollution  
- Acid rain  
Our adjustable hooks (Material: SUS430) just passed rigorous SGS 
testing (Report: XMIN2505001404ML01_EN) with critical advantages:
  
Chemical Combatants
Element    Industry Max    FarSun    Advantage
S (Sulfur)    0.030%    0.005%    Kills corrosion initiation
C (Carbon)    0.120%    0.024%    Prevents intergranular rust
P (Phosphorus)    0.040%    0.026%    Boosts strength without brittlenes

Mechanical Mastery
Tensile Strength: 467 MPa (▲3.8% above ASTM A240)
Yield Strength: 336 MPa (▲64% beyond minimum)
Elongation Rate: 28% (Absorbs seismic movement)
Real-World Engineering Edge
"The 0.34% manganese content is our secret – it enhances workability for complex roof angles without sacrificing strength."
– FarSun Materials Lead

Certified Peace of Mind:
Every production batch undergoes the same as SGS-tested samples.
