Heavy plates and Hot rolled Sheets for pressure vessel and boiler construction

As a reliable partner for the manufacture of pressure vessels, heat exchangers, transport containers and trays, we stock various steel grades in our warehouses. Our customers who purchase Heavy plates and coil sheets from us are active in a wide range of industries or act as suppliers. These include industries such as petrochemicals, chemicals, pharmaceuticals, food production, waste management, power plant technology and the energy and environmental sectors.

 

The requirements for the Steel grades properties of pressure vessel steel grades are demanding, as they have to withstand extreme loads. Temperature resistance, both at high and low temperatures depending on the intended use and location, and weldability play a decisive role here. If corrosion resistance is required, we at UnionStahl are your competent partner. We have specialized in the storage of sour gas-resistant steel grades. Our Steel grades comes from renowned Western European manufacturers that are recognized by key players in the energy, oil and gas sectors.

A wide range of pressure vessel Steel grades

The steel grades we supply for pressure vessel and boiler construction comply with international standards and regulations. We stock unalloyed, alloyed and heat-resistant pressure vessel steel grades in accordance with DIN EN 10028-2 and normalized weldable fine-grained structural steel grades in accordance with DIN EN 10028-3. Our range also includes the renowned Dillinal P460/630 and P440NJ4 brand steel grades from Dillinger Hüttenwerke. These steel grades are suitable for the construction of containers and tanks such as tank trucks and tank containers, as well as for the transportation of gas, including LNG. The sheets are characterized by increased strength and are part of our full range available at any time.

 

Another unique selling point in our competitive environment are the steel grades P690QL2, P690QL1 and P690QH in accordance with EN 10028-6. These high-strength quenched and tempered fine-grain structural steel grades in accordance with VdTÜV Steel grades sheet 257 have proven themselves in hot tensile tests at 300 °C.

We love the extreme and the extraordinary

We store sheet metal for pressure vessel and boiler construction in as many dimensions as possible in order to be able to optimally meet the needs of our customers. Widths of up to 4,000 mm and lengths of up to 16,000 mm – these unusual sizes are not uncommon for us. By stocking intermediate thicknesses, we make it possible to reduce the weight of the containers. Subsequent tests such as PWHT, hardness tests, tensile tests and notched bar impact tests are just some of the services we offer to meet a wide range of requirements. Get in touch with us. We are happy to support and advise you in the processing of specifications in order to advance the realization of your project in the best possible way.
