Abstract

A corrosion-resistant coated brass metal coated with a corrosion resistant alloy. The corrosion resistant alloy is a tin metal alloy or a tin and zinc metal alloy. The corrosion resistant metal alloy may also include one or more metal additives to improve the coating process and/or to alter the properties of the tin and zinc metal alloy.

Claims (15)

1. A corrosion-resistant petroleum receptacle comprising at least one shell member that includes a seal that maintains fluid within an interior of said petroleum receptacle, said seal including a weld, a solder, bonding, and combinations thereof, said at least one shell member including a carbon steel metal strip having a top and bottom surface coated with a corrosion-resistant tin-zinc alloy which forms two phases upon cooling and which resists corrosion by petroleum products, said carbon steel strip having an average thickness of about 127-5080 microns prior to coating with said tin-zinc alloy, said carbon steel strip including a plated nickel layer on at least one surface of said carbon steel metal strip prior to said tin-zinc alloy being applied to said carbon steel metal strip, said nickel layer having an average thickness of less than about 3 microns, said carbon steel metal strip including a hot dipped coating of said tin-zinc alloy by at least partial immersion in molten tin-zinc alloy which at least partially forms a heat created intermetallic layer between said carbon steel metal strip and said corrosion resistant tin-zinc alloy, said tin-zinc alloy comprising zinc and a majority of tin and having a tin plus zinc content of at least about 95 weight percent, said zinc content less than about 30 weight percent, said tin-zinc alloy having an average coating thickness of about 2.5-1270 microns, said average coating thickness of said tin-zinc alloy being greater than the average coating thickness of said plated nickel layer, said heat created intermetallic layer including iron, manganese, nickel, tin and zinc.

2. The corrosion-resistant petroleum receptacle as defined in claim 1 , wherein said tin-zinc alloy includes at least one metal additive selected from the group consisting of copper, lead, magnesium, manganese, nickel, silicon, titanium, and mixtures thereof.

3. The corrosion-resistant petroleum receptacle as defined in claim 2 , wherein said tin-zinc alloy includes copper.

4. The corrosion-resistant petroleum receptacle as defined in claim 2 , wherein said tin-zinc alloy includes magnesium.

5. The corrosion-resistant petroleum receptacle as defined in claim 2 , wherein said tin-zinc alloy includes manganese.

6. The corrosion-resistant petroleum receptacle as defined in claim 2 , wherein said tin-zinc alloy includes nickel.

7. The corrosion-resistant petroleum receptacle as defined in claim 2 , wherein said tin-zinc alloy includes silicon.

8. The corrosion-resistant petroleum receptacle as defined in claim 2 , wherein said tin-zinc alloy includes titanium.

9. The corrosion-resistant petroleum receptacle as defined in claim 2 , wherein said tin-zinc alloy includes lead.

10. The corrosion-resistant petroleum receptacle as defined in claim 2 , wherein said tin-zinc alloy includes aluminum.

11. A corrosion-resistant petroleum receptacle comprising at least one shell member that includes a seal that maintains fluid within an interior of said petroleum receptacle, said seal including a weld, a solder, bonding, and combinations thereof, said at least one shell member including a carbon steel metal strip having a top and bottom surface coated with a corrosion-resistant tin-zinc alloy which upon cooling forms a two phase alloy which resists corrosion by petroleum products, said carbon steel strip having an average thickness of about 127-5080 microns prior to coating with said tin-zinc alloy, said carbon steel strip including a plated nickel layer on at least one surface of said carbon steel metal strip prior to said tin-zinc alloy being applied to said carbon steel metal strip, said nickel layer having an average thickness of less than about 3 microns, said carbon steel metal strip including a hot dipped coating of said tin-zinc alloy by at least partial immersion in molten tin-zinc alloy which at least partially forms a heat created intermetallic layer between said carbon steel metal strip and said tin-zinc alloy, said tin-zinc alloy comprising zinc and a majority of tin and having a tin plus zinc content of at least about 95 weight percent, said zinc content in said corrosion-resistant tin-zinc alloy being less than about 30 weight percent, said tin-zinc alloy having an average coating thickness of about 2.5-1270 microns, said average coating thickness of said tin-zinc alloy being greater than the average coating thickness of said plated nickel layer, said tin-zinc alloy including manganese, said heat created intermetallic layer including iron, manganese, nickel, tin and zinc.

12. The corrosion-resistant petroleum receptacle as defined in claim 11 , wherein said heat created intermetallic layer includes at least one additional metal selected from the group consisting of aluminum, copper, lead, magnesium, silicon, titanium and mixtures thereof.

13. The corrosion-resistant petroleum receptacle as defined in claim 12 , wherein said heat created intermetallic layer includes at least one metal selected from the group consisting of copper, lead, silicon and mixtures thereof.

14. The corrosion-resistant petroleum receptacle as defined in claim 12 , wherein said tin-zinc alloy includes at least one metal additive selected from the group consisting of aluminum, copper, lead, magnesium, silicon, titanium and mixtures thereof.

15. The corrosion-resistant petroleum receptacle as defined in claim 13 , wherein said tin-zinc alloy includes at least one metal additive selected from the group consisting of copper, lead, silicon and mixtures thereof.
