Rolled homogeneous armour (RHA) is a type of vehicle armour made of a single steel composition hot-rolled to improve its material characteristics, as opposed to layered or cemented armour. Its first common application was in tanks.

軋壓均質裝甲（英文：Rolled Homogeneous Armor；德文：gewalzte homogene Panzerung），縮寫成「RHA」，又簡稱為均質裝甲是為鋼板之理論基礎象徵，RHA做為一種基數，用於對照軍事 裝甲車之效能。

Armour steels have historically delivered optimised ballistic performance against a range of battlefield threats, including both armour piercing and fragmentation threats. Such protection is provided at realistic areal densities for many ballistic applications and also for an affordable price.

MIL A 12560 is commonly referred to as RHA (Rolled Homogeneous Armor) steel. Frequently used in the manufacturing of armored military vehicles, tanks, and other defense equipment, its unique characteristics make it an ideal choice for military-grade applications.

2022年3月16日 · Ballistic steels are made into slabs by the casting process, and then hot rolled into plates of the desired thicknesses. This is also known as rolled homogenous armor (RHA) steel [4]. Next, they are subjected to austenitizing, quenching and tempering processes to obtain the desired properties [5].

Through augmentation of a generic chemical composition for standard rolled homogeneous armor (RHA) material, and optimization of heat treatment, greater hardenability, and higher hardness levels were attained.

During recent decades, due to cost-saving fabrication techniques and more complex vehicle configurations, rolled homogeneous armor (RHA) steel has supplanted cast steel, as demonstrated by the...

RHA steel is a commonly used material in armor systems and ballistic testing. It is also a de facto standard in the assessment of ballistic performance. Penetration performance of KE penetrators, explosively formed penetrators, and shaped charge jets is typically described in terms of their depth of penetration into a thick stack of RHA target ...
