Description

1.4550 (X6CrNiNb1810) is an austenitic grade of stainless steel stabilised with niobium to prevent carbide precipitation and inter-granular corrosion, especially in welded fabrications. It resists oxidation and scaling and is used up to 900°C for aerospace applications including aircraft exhaust manifolds and other elevated temperature applications. The weldability of S130 is excellent, and with no post-weld heat treatment required it is particularly suitable for welded structures. It shows the following features and properties:


  • High strength and toughness
  • Good oxidation resistance up to 900°C
  • High corrosion resistance
  • Related Standards
