Sch80S Stainless Steel Pipe Tube EN 1.4571 Intended For Pipelines
EN 1.4571 (X6CrNiMoTi17-12-2) Stainless Steel Tube Sch80S intended for pipelines
DIN EN 1.4571 material (X6CrNiMoTi17-12-2) is manufactured by adding titanium (Ti) to EN 1.4401 stainless steel (X5CrNiMo17-12-2) to enhance resistance to intergranular corrosion. Titanium improves the corrosion resistance of stainless steel, particularly intergranular corrosion, effectively preventing sensitization of stainless steel while also enhancing stability in high temperature and high pressure environments. When the mass fraction of titanium is between 0.03% and 0.1%, the yield strength of the steel is improved. Consequently, EN 1.4571 material offers superior temperature resistance, corrosion resistance, and sensitization resistance compared to 1.4401.
- Construction encasement, doors, windows and armatures
- Off-shore modules
- Container and tubes for chemical tankers
- Warehouse and land transportation of chemicals
- Food and beverages, pharmacy industries
- Synthetic fibre, paper and textile plants
- Pressure vessels
Due to the Ti-alloy composition, resistance to intergranular corrosion is guaranteed after welding.
