When the Great Patriotic war began Beloretsk Metallurgy Integrated Plant increased steel and cast-iron production by 1.5 times. Generally gross production increased by 53% during the war. Beloretsk enterprises were leading suppliers of metal and metal goods meeting the needs of the front.
The Bashkir ASSR housed equipment from Khartsuzsk and Odessa plants as well as from bimetal workshop of Moscow Serp i Molot Metallurgical Plant. As early as in October 1941 the enterprise acquired producing and rolling high-quality steel.
Bashkir deposits of refractory clay, quartzite and magnesite facilitated refractory goods production at Beloretsk Metallurgy Integrated Plant.
On the 8th of December the plant became the first in the USSR using open-hearth method to smelt metal for ball-bearings.
In 1942 the machine-tool and cable plant managed to acceleratedly acquire production of steel carbon wire with advanced resistance and increased calibration precision.
Within 1942-1943 USSR steel wire engineers pioneered acquiring drawing of complicated iron-chromium-aluminum alloy of the ferrous group.
In 1944 the USSR launched production of hot-rolled wire rod form grade 8 high speed steel of iron-chromium-aluminium alloy. The State Committee for Defence initiated urgent production of incendiary munitions and Katysha guard mortar missile noses at the metallurgic plant.
