Definitions

  • Ti acts in a grain-refining manner as a carbide forming agent, whereby at the same time the strength, toughness and expansion properties are improved and the inter-crystalline corrosion is reduced. Contents of Ti of more than 2 wt. % impair the expansion properties for which reason a maximum content of 2 wt. % is set.
