Martensitic steel 1.4057 annealed round bar, flat bar, forgings X17CrNi16-2 ESR ingot in stock, hot forged, rolled, quenched and tempered condition
TECHNICAL DATA SHEET - 1.4057
MATERIAL CATEGORY: 16.0Cr - 2.0Ni martensitic type
PRODUCT DESCRIPTION
1.4057 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.
