WebThe corrosion behaviour of the two grades 1.4571 and 1.4404 is in general very similar. Only a few substantial differences are to mention: The titan-stabilized 1.4571 has a higher sensitivity for pitting corrosion. Therefore, the same grade is less consistent against (chloride-induced) stress corrosion cracking. WebDie casting tooling usually has a limited lifetime due to thermal fatigue cracking or ‘heat checking’ of the die surface, caused by high cyclical thermal loads. The surface of a die is exposed to a rapid increase in temperature as metal fills the die and the casting solidifies. http://badgermetal.com/ tallas schmutzwasserpumpe sa 60/3
