一、前言 603钢是我国自行研制的无镍稀土轧制装甲钢,主要用于制造中型坦克车体等防护装甲零件。 抗弹性能是评定装甲防护指标的首要标准。装甲抗弹性能具体是指:抗贯穿、抗开裂、抗崩落和抗低温破坏的能力。目前各国都在尽量采用非射击的试验方法,但最终都 I. Introduction 603 steel is our own research and development of nickel-free rare-earth rolling armored steel, mainly used in the manufacture of medium-sized tanks and other protective body armor parts. Anti-ballistic performance rating is the most important indicator of armor protection. Armor anti-balling performance specifically refers to: anti-penetration, anti-cracking, anti-collapse and anti-low temperature damage ability. At present, all countries are trying their best to adopt non-shooting test methods, but in the end all
