Outokumpu 1.4510

Família genérica: Steel - Wrought - Stainless - FerriticFornecido por: Outokumpu
Ferritic stabilized stainless steel
Type 17Cr-Ti stainless steel: EN 1.4510, AISI 439

Applications
  • Automotive exhaust system parts: mufflers, pipes, catalytic converters, support parts.
  • Domestic appliance internal parts

Welding
  • Conventional welding methods are applicable, austenitic 308L and ferritic 430LNb or 439 filler metals can be used.
  • Austenitic filler metal will result in more a ductile weld.
  • Ferritic filler metals are recommended to use in sulphuric environments and under thermal stresses.
  • Shielding gases should be based on Ar/He, mixed with maximum of 2 % oxygen or carbon dioxide to improve the arc stability. Hydrogen and nitrogen additions are forbidden.
  • Heat input should be minimized to reduce the grain coarsening effect in the heat-affected zone.
  • Titanium stabilization prevents sensitization effect in the heat-affected zone.
  • Adequate corrosion resistance in the welded joint is achieved using either mechanical descaling or pickling.

Fabrication
  • Grade 1.4510 can be formed using typical forming processes like folding, bending, drawing, etc.
  • It has higher minimum proof strength than standard austenitic stainless steel grade 1.4301 / AISI 304 in combination with lower work hardening behavior.
  • Due to the stabilization, the r-value is higher compared to the non-stabilized ferritic stainless steel such as 1.4016.
  • These characteristics mean excellent deep-drawability and other forming related properties.

Corrosion resistance
  • Outokumpu produces grade 1.4510 with a typical chromium content of 17 wt-%.
  • Titanium alloying reduces sensitivity for intergranular corrosion.
  • Oxidation resistance is good up to 950°C.
  • Relatively high chromium content improves resistance to crevice corrosion
  • Grade 1.4510 is not susceptible to chloride induced stress corrosion cracking.
  • The best material performance is reached usually with the help of adequate design and regular cleaning during use (if applicable)
