GJB 1220A Specification for Alloy Structure Steel Bar for Artillery Parts 35CrMnSiA Stock Available Round bar, Flat bar, Tube 35CrMnSiA Forgings
MATERIAL STANDARD DATASHEET - GB 35CrMnSiA
MATERIAL CATEGORY - Specification for Alloy Structure Steel Bar for Artillery Parts,
PRODUCT DESCRIPTION
The alloy is usually produced by EAF + VD + LF / BEF 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.
Stock Available: Round bar diam. 16 ~ 200mm
