Why Choose EN 10028-7 1.4571 316Ti?
1. Designed for Pressure Equipment Applications
EN 10028-7 provides requirements for stainless steel flat products intended for pressure equipment applications. This makes it particularly relevant when purchasing stainless steel sheet or plate for pressure-related industrial equipment.
2. Titanium-Stabilized Structure
The addition of titanium (Ti) stabilizes carbon in the steel and helps reduce the risk of chromium carbide precipitation during certain elevated-temperature exposures.
This makes 316Ti attractive for selected applications involving prolonged service at elevated temperatures.
3. Excellent Corrosion Resistance
The combination of chromium, nickel and molybdenum provides excellent general corrosion resistance.
Molybdenum also improves resistance to localized corrosion such as:
Pitting corrosion
Crevice corrosion
Chloride-related corrosion
4. Good Elevated-Temperature Performance
316Ti is frequently selected for industrial equipment exposed to elevated temperatures, particularly where corrosion resistance and structural stability are both important.

Frequently Asked Questions (FAQ)
What is EN 10028-7 1.4571?
EN 10028-7 1.4571 refers to a stainless steel flat product grade for pressure equipment, with material number 1.4571 and commonly known as 316Ti. Its EN designation is X6CrNiMoTi17-12-2.
Is 1.4571 the same as 316Ti?
Yes. EN 1.4571 is commonly designated as AISI 316Ti, with UNS S31635 as the corresponding UNS designation.
What is the difference between 316Ti and 316L?
316Ti is titanium stabilized, while 316L is a low-carbon stainless steel. 316Ti is particularly considered for selected elevated-temperature applications, whereas 316L is widely used for welded corrosion-resistant equipment.
Is 1.4571 suitable for pressure vessels?
Yes, 1.4571 / 316Ti can be used for selected pressure equipment applications when it meets the applicable material, design, fabrication and certification requirements.
What does 1D surface mean?
1D is a common hot-rolled stainless steel surface condition. It is generally associated with annealing and pickling, producing a matte and non-reflective industrial surface.
Is 316Ti corrosion resistant?
Yes. 316Ti provides excellent general corrosion resistance and good resistance to pitting and crevice corrosion due to its chromium, nickel and molybdenum alloying system.
Can 316Ti stainless steel be welded?
Yes. 1.4571 / 316Ti can be welded using common stainless steel welding processes. The welding procedure should be selected according to material thickness, service conditions and applicable fabrication requirements.
Is 316Ti better than 316L?
Neither grade is universally "better." 316L is generally preferred for many welded applications because of its low carbon content, while 316Ti may be preferred for certain applications involving prolonged elevated-temperature exposure.
What sizes are available for 1.4571 stainless steel sheet?
Thickness, width and length can be supplied according to the applicable standard, mill capability and customer requirements. Custom sizes can also be available for project orders.
