K33X – 1.4513

K33X – 1.4513

Our KARA range. The “X” means that this molybdenum-containing, niobium-stabilised, 18% chromium Ferritic Stainless Steel is ideal for exhaust applications.

Main features

Excellent resistance to corrosion (in exhaust environments), pitting corrosion (similar to austenitic 1.4301), stress and intergranular corrosion, and oxidation (up to 850°C); easy to form and weld; low thermal expansion coefficient; high thermal conductivity (resulting in a homogenous aspect).

Applications

  • Exhaust system muffler (as a substitute to the 1.4301 grade, K33X increases a muffler’s life time).
  • Various after-treatment systems (particulate filter system, Urea SCR)
