GJB 1951-94 Material Specification for Quality Structure Steel Bars for Aviation 15CrA Stock Available Round bar, Flat bar 15CrA Forgings
MATERIAL STANDARD DATASHEET - GJB 15CrA
MATERIAL CATEGORY - Specification for Quality Structure Steel Bars for Aviation.
MATERIAL CATEGORY - Specification for Quality Structure Steel Bars for Aviation.
PRODUCT DESCRIPTION
The alloy is usually produced by EAF + VD + LF / BEF / VIM 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, or bright annealing specially.
Final heat treatment - Quenched and tempered.
