Description 1.5736 Alloy steel supplier, Round bar 1.5736 Inventory Steelmaking, Hot forging, rolling, Heat treatment, Cold working.
TECHNICAL DATA SHEET - W-Nr 1.5736
MATERIAL CATEGORY - Hardened and tempered 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.
