GJB 3324A-2021 Specification for high strength steel plates for aerospace solid motor
1 Scope
This specification specifies the requirements for high strength steel plates for aerospace solid motor.
This standard is applicable to cold-rolled steel plates with a nominal thickness not exceeding 6mm and hot-rolled steel plates with a nominal thickness not exceeding 10mm (hereinafter referred to as "steel plates") for aerospace solid motor. After negotiation between the supplier and the purchaser, steel plates of other thickness specifications may also be supplied.
