444 Stainless Steel (UNS S44400, SUS444, 1.4521 / X2CrMoTi18-2)

444 is a ferritic stainless steel containing approximately 18% chromium and 2% molybdenum, with very low carbon and nitrogen content. The molybdenum addition gives 444 outstanding resistance to pitting corrosion and stress corrosion cracking — significantly better than 430 and comparable to 316L in many chloride environments.

Key Features

  • Excellent pitting and crevice corrosion resistance in chloride media
  • Superior stress corrosion cracking resistance versus austenitic grades
  • Good thermal conductivity and low thermal expansion
  • Attractive 2B, BA and polished surface finishes

Category: Ferritic stainless steel, ultra-low carbon & nitrogen, stabilized with Ti/Nb, 18Cr‑2Mo gradeATI

Chinese equivalent: S11972 (019Cr19Mo2NbTi)

1. Chemical Composition (wt%, ASTM A240 / UNS S44400)


Element Specification
C ≤0.025
Si ≤1.00
Mn ≤1.00
P ≤0.040
S ≤0.030
Cr 17.50 – 19.50
Mo 1.75 – 2.50
Ni ≤1.00
N ≤0.035
Ti + Nb ≥0.2 + 4×(C+N), max 0.80
Fe Balance

Notes:

  • Ultra-low C & N prevent intergranular corrosion after welding.
  • Molybdenum greatly improves resistance to pitting & crevice corrosion in chloride environments.
  • Ti/Nb stabilisation binds residual carbon and nitrogen, avoiding weld sensitizationATI.

2. Mechanical Properties (Annealed condition, room temperature, minimum values ASTM A240)


Property Metric Imperial
Ultimate Tensile Strength (Rm) ≥415 MPa ≥60 ksi
0.2% Offset Yield Strength (Rp0.2) ≥275 MPa ≥40 ksi
Elongation (A, 2 in gauge) ≥20 % ≥20 %
Hardness ≤217 HB ≤96 HRB

Physical & Metallurgical Properties

  • Density: ~7.70 g/cm³
  • Elastic Modulus: ~200 GPa
  • Thermal conductivity: ~26.8 W/(m·K) (higher than 304/316 austenitic stainless steel)
  • Coefficient of thermal expansion: ~10.5 ×10⁻⁶ /K (lower than austenitic grades)
  • Magnetic: Ferromagnetic
  • Not heat-treatable for hardening; strength can only be increased by cold working
  • Excellent resistance to chloride stress corrosion cracking (SCC) (big advantage over 304 / 316L)ATI

3. Corrosion Characteristics

  1. Good resistance to pitting, crevice corrosion in hot water and low-to-moderate chloride media.
  2. Virtually immune to chloride stress corrosion cracking, which is a common failure mode for 304/316L in hot chlorinated water.
  3. Stabilized chemistry → no intergranular corrosion after welding, no post-weld annealing required.
  4. Not suitable for strong oxidizing acids (e.g. concentrated nitric acid).

4. Applications

  • Water heater tanks, hot water storage vessels, geysers (the most typical application for 444)
  • Heat exchanger tubes, evaporators for water, steam & mild brine service
  • Food & beverage processing equipment: brewery, wine, dairy machinery (FDA / NSF compliant)
  • Solar thermal water system components
  • Automotive exhaust parts
  • Marine atmosphere architectural cladding, roofing (low chloride marine environment)
  • Water treatment equipment, desalination pre-treatment components
  • Sanitary piping for hot potable water systems

5. Fabrication Notes

  • Weldable by GTAW (TIG), GMAW; matching ferritic filler metals recommended.
  • Formability is moderate; better than high-alloy ferritic stainless steel, inferior to 304.
  • Avoid long time exposure at 400–500°C (475°C embrittlement risk for ferritic stainless steel).
  • Cost advantage: No expensive nickel, so generally cheaper than 316L for hot water & chloride SCC service.
