Material Specifications:

• Alloy: UNS S32101 (21.5Cr-5Ni-1.6Mo-0.3N)

• Standards: ASTM A790 / EN 10216-5 (PED 2014/68/EU Optional)

• PREN Value: ≥26 (Superior to 304/316L)

• Density: 7.8 g/cm³ | Melting Range: 1420-1465°C

 

Key Advantages vs 316L:

 50% Higher Strength

• Yield Strength: 400 MPa (vs 170 MPa for 316L) → Thinner walls, 20% weight savings

 Cost Savings

• Lower nickel content (5% vs 10-12%) → 30% cheaper than 316L at equal performance

 Enhanced Corrosion Resistance

• Resists chloride stress corrosion cracking (SCC) better than 300-series stainless

• Ideal for brackish water, mild acids, and urban environments

 Sustainable Choice

• Reduced nickel content lowers carbon footprint vs traditional austenitics

 

Technical Parameters:

Property	Value	Test Standard
Tensile Strength	600-800 MPa	ASTM A370
Pitting Temperature	>25°C (3% NaCl)	ASTM G48
Hardness	290 HB Max	ASTM E10
