🔎 What is AISI 347 Stainless Steel?

AISI 347 is an austenitic chromium-nickel stainless steel stabilized with niobium (columbium).

• Provides excellent resistance to intergranular corrosion after welding or prolonged high-temperature exposure.

• Offers superior oxidation and creep resistance in the temperature range of 800–1500 °F (427–816 °C).

• Widely used in heat-resistant, chemical, and high-stress applications.

❓ Frequently Asked Questions (FAQs)

Q1: What makes AISI 347 different from AISI 321?
AISI 347 is stabilized with niobium (columbium), while AISI 321 uses titanium. AISI 347 offers better resistance to intergranular corrosion after welding.

Q2: What temperature range can AISI 347 handle?
AISI 347 resists oxidation and creep in continuous service up to 816°C (1500°F).

Q3: Is AISI 347 stainless steel weldable?
Yes, it offers good weldability, and niobium stabilization prevents carbide precipitation during welding.

Q4: Which industries use AISI 347 the most?
Aerospace, power generation, petrochemical, thermal equipment, and food processing industries.

Q5: Do you provide AISI 347 fasteners and valves?
Yes, we manufacture and supply AISI 347 fasteners and valves for industrial use.
