Since 1918, steam engines and wagons have been repaired at the enterprise, tanks and armored hull components, bloomings and the first towing steamers have been manufactured.

In 1958, the development of nuclear power engineering began. In particular, the first vessel of a water-cooled power reactor with a capacity of 210,000 kilowatts was manufactured at Izhora Works.

In 2009, DSP-120 - a super-powerful steel-smelting complex of the latest generation with production capability of more than 250 thousand tons of special steels per year was put into operation in the metallurgical production facility.

In 2014, the manufacturing cycle of a unique shell of the new generation nuclear reactor core of VVER-TOI project was completed. The pilot-standard shell about 6 meters long was forged on 12000 tnf automated forging plant from an ingot weighing 420 tons, underwent heat treatment and machining and entered on systems testing.

2017 – The reactor vessel for the second power unit of Leningrad NPP-2 was shipped.

2022 - The works became part of AEM-Technologies Company.
