58SiMn steel square bar for shell bodies manufacturing

The 58SiMn steel square bar is used for fragmentation shell bodies . Made in china. So the quality requirements are even higher.
Its alloy element content is lower than the other similar grade steel.
It has good hardenability and stable mechanical properties.

The 83-type 122-mm grenade manufactured with it has undergone multiple shooting range power and strength tests. The results show that: under the condition of unchanged projectile structure and explosives, the effective fragment number of 58SiMn steel is increased by 38.3% compared with D60 steel Kill area increased by 52.8%
At present. 58SiMn steel square bar has not only been successfully used in the manufacture of 83-type 122-mm grenade. But also under the heat treatment conditions, on the higher-bore pressure 120-mm grenade, it has also reached the design and finalization stage, and it has broad prospects for other types of projectiles. The comprehensive performance of the steel has reached the advanced level of similar international steel.
