What We Do
Core Advantages of 1.4980
This alloy remains structurally sound up to 1200°C, resisting deformation and scaling under intense heat. It’s an ideal choice for high-temperature piping in power plants and industrial furnaces, ensuring consistent performance where other materials might fail.
Thanks to its high chromium and nickel content, 1.4980 effectively combats oxidation and chemical attacks. This protects stainless steel fittings from rust and wear, guaranteeing durability in corrosive settings like chemical processing plants.
Its well-balanced composition enables easy welding and machining without cracking or distortion. This streamlines the manufacturing of intricate stainless steel pipe systems, cutting production time and costs while maintaining quality and precision.
Even at elevated temperatures, 1.4980 retains remarkable tensile strength, preventing sagging or structural collapse. This ensures the stability and safety of pipe networks in demanding applications like gas turbines and thermal plants.
It endures repeated heating and cooling cycles without cracking or weakening. This minimizes failure risks in fittings under thermal stress, enhancing longevity and reliability in dynamic, high-heat environments.
Applications of 1.4980
- Stainless Steel Pipes: It powers heat exchange systems in power plants with top heat resistance.
- Stainless Steel Pipe Fittings: It ensures safe, stable connections in gas turbine pipelines.
