A process for manufacturing a recovery annealed coated steel substrate for packaging applications, comprising the steps of: • providing a steel slab or strip suitable for producing a low-carbon, an extra-low-carbon or an ultra-low-carbon hot rolled strip for producing packaging steel by hot rolling at a finishing temperature higher than or equal to the Ar 3 transformation point; • cold-rolling the resulting steel strip to produce a single reduced steel substrate; • electrodepositing a tin layer on one or both sides of the single reduced steel substrate to produce a tin-coated steel substrate, wherein the coating weight of the tin layer or layers onto one or both sides of the substrate is at most 1000 mg/m 2; • heating the tin-coated steel substrate at a heating rate exceeding 300°C/s followed by annealing the tin-coated steel substrate at a temperature T a of between 513°C and 645°C for an annealing time t a: o to convert the tin layer into an iron-tin alloy layer which contains at least 90, preferably at least 95, weight percent (wt.%) of FeSn (50 at.% iron and 50 at.% tin), and o to simultaneously obtain a recovered microstructure and wherein no recrystallisation of the single reduced substrate takes place (i.e. recovery annealing); • fast cooling the annealed substrate at a cooling rate of at least 100°C/s; • wherein the steel comprises (in weight percentage): o a carbon content of 0.05% or less; o a nitrogen content of 0.004% or less; o a manganese content between 0.05 to 0.5%; o a phosphorous content of 0.02% or less; o a silicon content of 0.02% or less; o a sulphur content of 0.03% or less; o an aluminium content of 0.1% or less; o optionally one or more of ▪ a niobium content between 0.001% and 0.1%; ▪ a titanium content between 0.001% and 0.15%; ▪ a vanadium content between 0.001% and 0.2%; ▪ a zirconium content between 0.001% and 0.1%; ▪ a boron content between 5 and 50 ppm; o the remainder being iron and unavoidable impurities. • providing a steel slab or strip suitable for producing a low-carbon, an extra-low-carbon or an ultra-low-carbon hot rolled strip for producing packaging steel by hot rolling at a finishing temperature higher than or equal to the Ar 3 transformation point; • cold-rolling the resulting steel strip to produce a single reduced steel substrate; • electrodepositing a tin layer on one or both sides of the single reduced steel substrate to produce a tin-coated steel substrate, wherein the coating weight of the tin layer or layers onto one or both sides of the substrate is at most 1000 mg/m 2; • heating the tin-coated steel substrate at a heating rate exceeding 300°C/s followed by annealing the tin-coated steel substrate at a temperature T a of between 513°C and 645°C for an annealing time t a: o to convert the tin layer into an iron-tin alloy layer which contains at least 90, preferably at least 95, weight percent (wt.%) of FeSn (50 at.% iron and 50 at.% tin), and o to simultaneously obtain a recovered microstructure and wherein no recrystallisation of the single reduced substrate takes place (i.e. recovery annealing); o to convert the tin layer into an iron-tin alloy layer which contains at least 90, preferably at least 95, weight percent (wt.%) of FeSn (50 at.% iron and 50 at.% tin), and o to simultaneously obtain a recovered microstructure and wherein no recrystallisation of the single reduced substrate takes place (i.e. recovery annealing); • fast cooling the annealed substrate at a cooling rate of at least 100°C/s; • wherein the steel comprises (in weight percentage): o a carbon content of 0.05% or less; o a nitrogen content of 0.004% or less; o a manganese content between 0.05 to 0.5%; o a phosphorous content of 0.02% or less; o a silicon content of 0.02% or less; o a sulphur content of 0.03% or less; o an aluminium content of 0.1% or less; o optionally one or more of ▪ a niobium content between 0.001% and 0.1%; ▪ a titanium content between 0.001% and 0.15%; ▪ a vanadium content between 0.001% and 0.2%; ▪ a zirconium content between 0.001% and 0.1%; ▪ a boron content between 5 and 50 ppm; o the remainder being iron and unavoidable impurities. o a carbon content of 0.05% or less; o a nitrogen content of 0.004% or less; o a manganese content between 0.05 to 0.5%; o a phosphorous content of 0.02% or less; o a silicon content of 0.02% or less; o a sulphur content of 0.03% or less; o an aluminium content of 0.1% or less; o optionally one or more of ▪ a niobium content between 0.001% and 0.1%; ▪ a titanium content between 0.001% and 0.15%; ▪ a vanadium content between 0.001% and 0.2%; ▪ a zirconium content between 0.001% and 0.1%; ▪ a boron content between 5 and 50 ppm; ▪ a niobium content between 0.001% and 0.1%; ▪ a titanium content between 0.001% and 0.15%; ▪ a vanadium content between 0.001% and 0.2%; ▪ a zirconium content between 0.001% and 0.1%; ▪ a boron content between 5 and 50 ppm; o the remainder being iron and unavoidable impurities.
