Description
Es wurde gefunden, daß überraschenderweise hochlegierte Ti-stabilisierte Stähle des Types 18/10, bei denen der Kohlenstoffgehalt oder der Titangehalt oder der Aluminiumgehalt über dem in dem DD-WP 155434 angegebenen Maximalwerten liegt, eine verbesserte Kaltbildsamkeit aufweisen, wenn folgende Bedingungen erfüllt sind:It has surprisingly been found that high-alloy Ti-stabilized steels of the 18/10 type, in which the carbon content or the titanium content or the aluminum content is above the maximum values specified in DD-WP 155434, exhibit improved cold formability if the following conditions are met:
K1 = %C x %Ti x 10 + %AI S 0,6 und/oderK 1 =% C x% Ti x 10 +% Al S 0.6 and / or
K2 = %C x %Ti x %AI x 100 S 0,65.K 2 =% C x% Ti x% Al x 100 S 0.65.
Bei der Herstellung entsprechender Stähle muß somit nicht mehr der Gehalt aller drei die Kaltbildsamkeit beim Kaltpilgern beeinflussenden Elemente unter einem Maximalwert gesenkt werden, sondern es reicht aus, den Gehalt eines oder zweier Elemente entsprechend den genannten Bedingungen einzustellen. Das ermöglicht eine Vereinfachung des metallurgischen Prozesses.In the production of corresponding steels, therefore, it is no longer necessary to reduce the content of all three elements influencing the cold image formation during cold pilgering below a maximum value, but it is sufficient to set the content of one or two elements in accordance with the conditions mentioned. This allows a simplification of the metallurgical process.
Die Erfindung soll nachfolgend am Beispiel der Stahlmarke X 8 Cr Ni Ti 18.10 TGL 7143 näher erläutert werden.The invention will be explained in more detail below using the example of the steel brand X 8 Cr Ni Ti 18.10 TGL 7143.
Obwohl im I.Beispiel der Al-Gehalt, im 2.Beispiel der C-Gehalt und im 3.Beispiel der Ti-Gehalt über den im DD-WP 155434 angegebenen Maximalwerten liegen, war bei allen drei Schmelzchargen eine gute Kaltbildsamkeit beim Kaltpilgern zu verzeichnen.Although in the I example the Al content, in the 2nd example the C content and in the 3rd example the Ti content are above the maximum values given in DD-WP 155434, a good cold formability in cold pilgering was observed for all three hot melt batches ,
