TECHNICAL DATA SHEET - WS 1.5415
 
MATERIAL CATEGORY: High temperature structural steel 
PRODUCT DESCRIPTION
The alloy is usually produced by EAF / VD / LF followed by electroslag refining (ESR) if necessary for special purpose. Bars and, where applicable, forgings are subjected to ultrasonic examination based on the different level according to the buyers' requirements.
Bars are usually supplied bright in the annealed condition.
Final heat treatment - Quenched and tempered.
