Cast Iron Resistance to Extreme Cold. PGO S.A. Śrem Technology for the Most Demanding Applications
Castings for Sub-Zero Applications – PGO Technology for Critical Industries
In many industrial sectors, reliability in extremely low temperatures is not optional – it is essential. Components used in railway systems, gas energy, offshore industries, and industrial machinery must retain their mechanical properties even under arctic conditions. In these applications, standard materials fail – becoming brittle, prone to cracking, and unable to absorb mechanical energy. That is why material solutions designed for impact resistance at sub-zero temperatures are crucial.
Mechanical Properties of Cast Iron in Extreme Cold
As the temperature drops, most metals transition from ductile to brittle behavior. This means that under dynamic loads, components do not deform but instead crack – posing a real threat to operational safety. This requires specialized impact testing under cryogenic conditions. PGO S.A. Śrem Iron Foundry addresses these challenges by developing proprietary material solutions that meet the demands of components operating at temperatures as low as -40°C.
PGO Śrem Technology – EN-GJS-400-18-LT Cast Iron with Enhanced Impact Resistance
The engineering team at PGO S.A. Śrem has developed a variant of spheroidal graphite cast iron, EN-GJS-400-18-LT, which maintains high impact resistance even at extremely low temperatures. In tests conducted at -40°C, the material achieved results comparable to GJS-EN-350-22LT, with an average impact value of 12 J and a minimum single value of 9 J. This level of toughness makes this cast iron a safe choice for applications where not only durability but also reliability in harsh environmental conditions is required.
Safe Operation in Arctic Conditions – PGO’s Advantage
Castings manufactured using PGO Śrem technology perform well in extreme winter conditions, meeting stringent industrial requirements. This is the result of consistent investments in technological development and the expertise of the research and development team. With such advanced materials, PGO strengthens its position as a preferred supplier for industries that demand not only quality but also precisely tailored operating parameters. Choosing cast iron components resistant to extreme cold is a choice for operational certainty – even in the harshest environments.
