Short answer: Pressure vessels use carbon steel for low-temperature storage, 304/316L stainless for corrosive duty, duplex stainless for chloride-rich service, alloy steel for high-pressure and high-temperature shells, and clad plate to balance cost with corrosion life, all chosen against the pressure rating, temperature and medium.
At a Glance
Carbon Steel and Toughness
Storage and low-temperature shells use carbon steel with proven toughness; the base grades are in our Carbon Steel Supplier ve Karbon Çelik Çeşitleri, the strength data in our Güç Karşılaştırması and the joining in our Welding Joining Guide.
Stainless and Corrosive Media
Process vessels see acids and chlorides, so 304 and 316L stainless earn their keep; the grade pick is in our Stainless Steel Supplier ve 304 vs 316 guide, with the environment case in our Corrosion Resistance Guide and families in our Types and Grades of Steel.
Duplex, Alloy and Clad
Chloride service calls for duplex stainless, high pressure calls for alloy steel, and cost calls for clad plate; the corrosion angle is in our Corrosion Resistance Guide and strength in our Güç Karşılaştırması, with welding in our Stainless Welding Guide and the coating comparison in our Galvanized vs Stainless page.
Fabrication and Certification
Shells must be dimensionally true and certified; the dimensional limits are in our Tolerances Guide, the proof in our Mill Test Certificate Guide, the treatment in our Heat Treatment Guide and packing in our Export Packing Guide.
