Under high pressure, components must remain strong and dimensionally stable, with properties such as tensile strength, yield strength, and resistance to deformation being critical. Pressure fluctuations, temperature, and applicable standards also determine which quality is appropriate for the application. Discover below the high-pressure structural steels supplied by Hetraco, which are used for applications such as flanges, shafts, and pressure-loaded machine parts, as well as custom parts and small production runs.
High-pressure structural steels are used in technical environments where components must withstand high mechanical loads, pressure fluctuations, and strict requirements for reliability and safety. The material must not only be strong, but also maintain its dimensional stability and be well-suited to the specific application. Structural steels are used, among other things, in pressure-loaded machine parts, flanges, shafts, plates, fasteners, housings, and components for equipment manufacturing, mechanical engineering, energy, and process plants. Discover the structural steels available for order from Hetraco.
Properties of pressure-resistant steel
In high-pressure structural steel, properties such as tensile strength, yield strength, toughness, and resistance to deformation play an important role. The material must be able to withstand the load without compromising the component’s dimensions or functional properties. Depending on the application, grades such as S355, C45, or other unalloyed and low-alloy steels may be selected. Weldability, machinability, wall thickness, tolerances, and applicable standards also play a decisive role in the final choice of material.
Adaptation to pressure, load, and specifications
For structures subjected to high pressure, it is important that the selected grade is appropriate for the technical conditions under which the component will be used. Consider static or fluctuating pressure loads, mechanical forces, temperature, the medium, dimensions, and any requirements related to certification or traceability. Hetraco provides support for requests where standard materials do not directly meet the project specifications, such as in cases involving non-standard dimensions, small batches, custom items, specific processing requirements, or additional documentation.
