Quenched & tempered steel plate is often used in defence, transport, mining, and structural applications, as it is specifically designed for applications where the steel will be subjected to high-impact situations that demand high performance. The toughness-factor means greater resistance to wear and abrasion. That is why quenched and tempered steel is particularly useful in machinery and structures where greater abrasion resistance and higher yield strength are necessary, such as mining, quarrying, earth moving and construction.
