What is X2CrTi24 Annealed?
X2CrTi24 Annealed is X2CrTi24 in the Annealed temper — standard stocked condition for sheet, strip and plate — best combination of formability, weldability and corrosion resistance. X2CrTi24 Annealed has a yield strength of 320 MPa (46.4 ksi) and a tensile strength of 520 MPa (75.4 ksi) — weaker than 60% of stainless steel grades. Elongation at break is 22% and the elastic modulus is 220 GPa (31.9 Msi). X2CrTi24 Annealed has a density of 7.7 g/cm³ (0.278 lb/in³), lighter than 83% of stainless steel grades. It melts at 1,450°C (2,642 °F).
Advantages

Working with X2CrTi24 Annealed
Is X2CrTi24 easy to machine?
Machines like 430/441 but tougher: rigid setup, sharp positive-rake carbide, heavy flood coolant, moderate speed and generous feed to avoid work-hardened glazing and stringy chips.
Can X2CrTi24 be welded?
GTAW/GMAW/laser with Ar or Ar+He (no CO2), low heat input and fast travel to limit HAZ grain growth; Ti stabilisation avoids sensitisation, and matching ferritic or 309L/duplex filler is used depending on joint ductility needs.
Can X2CrTi24 be formed, bent or molded?
Good deep-drawing and roll-forming behaviour with low springback compared with austenitics, but limited stretch formability — keep bend radii ≥1t transverse and avoid heavy multi-stage stretching.
What surface finishes work on X2CrTi24?
Pickle and passivate (ASTM A967) or electropolish after fabrication; 2R/BA surfaces take a good mechanical polish, and no anodising applies — paint/PVD only for cosmetic coatings.
X2CrTi24 chemical composition (wt %)
Limits by weight percent from the governing specification, written the way the spec states them — a single maximum for impurities, a range for alloying elements, and the base element as balance. Nominal is the typical mid-range value.

X2CrTi24 Annealed — frequently asked
What is X2CrTi24 Annealed used for?
X2CrTi24 Annealed is typically used for exhaust system components, high-temperature process equipment, chemical processing parts, architectural and structural cladding and heat shields. In short: highest-Cr Ti-stabilized ferritic; better corrosion than 1.4611; low springback roll forming.
What is the yield strength of X2CrTi24 Annealed?
X2CrTi24 Annealed has a typical yield strength of 320 MPa (46.4 ksi) and a tensile strength of 520 MPa (75.4 ksi) — weaker than 60% of stainless steel grades. Strength varies by condition: see the 3 listed tempers.
Is X2CrTi24 Annealed easy to machine?
Reasonably — machinability is rated fair (48/100, better than 88% of stainless steel grades). Machines like 430/441 but tougher: rigid setup, sharp positive-rake carbide, heavy flood coolant, moderate speed and generous feed to avoid work-hardened glazing and stringy chips.
Can X2CrTi24 Annealed be welded?
Yes — weldability is rated very good (70/100). GTAW/GMAW/laser with Ar or Ar+He (no CO2), low heat input and fast travel to limit HAZ grain growth; Ti stabilisation avoids sensitisation, and matching ferritic or 309L/duplex filler is used depending on joint ductility needs.
What surface finishes work on X2CrTi24 Annealed?
Pickle and passivate (ASTM A967) or electropolish after fabrication; 2R/BA surfaces take a good mechanical polish, and no anodising applies — paint/PVD only for cosmetic coatings.
Can X2CrTi24 Annealed be formed, bent or molded?
Good deep-drawing and roll-forming behaviour with low springback compared with austenitics, but limited stretch formability — keep bend radii ≥1t transverse and avoid heavy multi-stage stretching.
What is the maximum service temperature of X2CrTi24 Annealed?
X2CrTi24 Annealed is rated for continuous use to about 950°C (1,742 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
