🔹 About DIN 1.4571 Steel

DIN 1.4571 (X6CrNiMoTi17-12-2), also known as AISI 316Ti / UNS S31635, is a titanium-stabilized austenitic stainless steel. The titanium prevents carbide precipitation during welding and high-temperature use, improving resistance to intergranular corrosion. It is widely used in chemical processing, refineries, marine, and power industries.

❓ Frequently Asked Questions (FAQ)

Q1: What is DIN 1.4571 stainless steel equivalent to internationally?
A: DIN 1.4571 is equivalent to AISI 316Ti, UNS S31635, BS 320S31, JIS SUS 316Ti, and other global standards.

Q2: What makes 1.4571 different from standard 316 stainless steel?
A: 1.4571 is titanium-stabilized, giving it higher resistance to intergranular corrosion and better high-temperature performance.

Q3: What are the main applications of DIN 1.4571?
A: It is used in chemical plants, refineries, marine structures, exhaust manifolds, boilers, and heat exchangers.

Q4: Is DIN 1.4571 weldable?
A: Yes, it has excellent weldability. Titanium prevents carbide precipitation, reducing the risk of weld decay.

Q5: What is the maximum service temperature of DIN 1.4571?
A: It can be used continuously at 800–900 °C and intermittently up to ~925 °C.

Q6: What standards cover DIN 1.4571 pipes and fittings?
A: Pipes are covered under ASTM A312/ASME SA312; fittings under ASTM A403/ASME SA403.

Q7: Does DIN 1.4571 resist chloride attack?
A: Yes, it has good resistance to chloride pitting and crevice corrosion, better than 304 but slightly below duplex grades.

Q8: What mechanical properties does DIN 1.4571 have?
A: Tensile strength is 515–690 MPa, yield strength 205–310 MPa, with elongation ≥40%.

Q9: Which industries commonly use DIN 1.4571?
A: Oil & gas, petrochemical, chemical processing, marine engineering, power plants, and food processing.

Q10: Do you provide third-party inspection and certification?
