AISI 316

AISI 316 is an austenitic stainless steel with excellent corrosion resistancehigher than that of theAISI 304thanks to the presence of molybdenum (Mo).

Chemical composition

X2CrNiMo17-12-2

ISO Standard

1.4401

It is the ideal choice for precision mechanical small parts with diameters between 3 and 32 mm e lengths up to 250 mmintended for aggressive environmentssuch as marine, chemical or medical.

Why use AISI 316?

1
Maximum corrosion resistance
- Superior to theAISI 304especially against chlorides, salts and acids
- Ideal for applications in marine, chemical and pharmaceutical environments
2
Excellent mechanical and fatigue strength
- Tensile strength up to 600 MPa
- Maintains high durability even under stress and thermal cycling
3
Excellent resistance to high temperatures
- Maintains properties up to 800°C
- Ideal for components exposed to heat and temperature variations
4
Good workability and weldability
- Less machinable than theAISI 303but more resistant
- Perfect for components requiring welding and assembly
5
Suitable for food, medical and pharmaceutical use
- Biocompatibleperfect for surgical instruments and implants
- Certified for contact with food and corrosive liquids

When to avoid AISI 316?

If needed greater workability (better AISI 303)

In applications not exposed to intense corrosion (theAISI 304)

If cost is a critical factor (the 316 is more expensive than 304)
