32CrNi2MoTiA A-8 aviation protection steel

32CrNi2MoTiA belongs to aviation steel A-8 series protective steel plate.
The protective steel plate implements the standard GJB 3019A-2008. This standard specifies conventional specifications such as material properties, composition, use and thickness requirements.

32CrNi2MoTiA A-8 protective steel surface hardened steel, after carburizing or carbonitriding and quenching, cold treatment and low temperature tempering, has good elastic resistance, good pressure processing and cutting performance. It is used for various aircraft protective structures, such as helmets, backrests, instrument panels, etc.
