Martensitic Steel 1.4057 Round bar, flat bar, forgings X17CrNi16-2 ESR Hot forging, Hot rolling, Heat treatment, Cold working or machined.
MATERIAL TECHNICAL DATA SHEET - Grade W-Nr 1.4057
MATERIAL CATEGORY - Martensitic type
PRODUCT DESCRIPTION
The alloy is usually produced by AOD / VOD / BEF followed by electroslag refining (ESR) / VAR if necessary for special purpose. Bars and, where applicable, forgings are subjected to ultrasonic examination based on the different levels according to the buyers' requirements.
Bars are usually supplied black/bright in the annealed condition.
Final heat treatment - Quenched and tempered.
