This steel may have no more than 0.16% carbon, no more than 1.10% manganese, no more than 0.010% phosphorus, no more than 0.05% sulfur, no more than 0.02% silicon, no more than 0.15% copper, no more than 0.10% nickel, no more than 0.1% chromium, no more than 0.03% molybdnium, no more than 0.40% aluminum, no more than 0.02% vanadium, no more than 0.0005% boron, no more than 0.003% titanium, and no more than 0.02% niobium.

First claim

What is claimed is:

1 . A carbon steel for use in high pressure hydrogen service, comprising greater than 1.20% manganese and greater than 0.035% sulfur.

2 . The carbon steel of claim 1 , wherein the manganese is between 1.20% and 1.35%.

3 . The carbon steel of claim 1 , wherein the sulfur is between 0.035% and 0.040%.

4 . The carbon steel of claim 1 , wherein the steel is ASME SA 350 LF1 or ASME SA 350 LF2 CL1.

5 . A fabricated article comprising, fabricating the article from the carbon steel of claim 1 , wherein the article is a seamless pipe or a seamless casing.

6 . The fabricated article of claim 5 , wherein the article is designed with a safety factor of at least 1.2.

7 . An assembly, comprising fabricating the assembly from two or more articles of claim 5 , wherein the two or more articles are welded together in accordance with ASME code B31.12.

8 . The assembly of claim 7 , wherein the assembly comprises a casing.

9 . The assembly of claim 8 , wherein the casing is selected from the group consisting of surface casing, intermediate casing, and production casing.

10 . The assembly of claim 7 , wherein the assembly comprises a cross country pipeline.

11 . The assembly of claim 7 , wherein the assembly comprises a wellhead component.

12 . The assembly of claim 11 , wherein said wellhead component is selected from the group consisting of a casing head, a casing spool, a casing hanger, a test plug, bull plug, a base plate, a tubing head, a tubing hanger, a tree cap test adapter, a positive choke, an adjustable choke, and a tubing head adapter.

13 . The assembly of claim 11 , wherein said wellhead component is a valve.

14 . The assembly of claim 13 , wherein said valve is selected from the group consisting of a gauge valve, a swab valve, a wing valve, a bleeder valve, a flow line valve, a master valve, a turning head valve, an intermediate casing head valve, and a lower casing head valve.

15 . A casing string, comprising fabricating the casing stream from two or more casings of claim 8 .

16 . The casing string of claim 15 , wherein the casing string is inserted into a well borehole and cemented at the surface.

17 . The casing string of claim 15 , wherein the casing string is inserted into a well borehole that penetrates cap rock and salt mass, wherein the casing string is cemented with gas blocking cement.

18 . The casing string of claim 15 , wherein the casing string is inserted into a well borehole that penetrates a salt mass, wherein the casing string is cemented with salt saturated cement.

19 . The casing string of claim 15 , wherein the casing string is inserted into an aquifer, wherein the casing string is cemented to the surface with gas block cement.

20 . The casing string of claim 15 , wherein the casing string is inserted into a depleted reservoir, wherein the casing string is cemented to the surface with gas block cement.

21 . The casing string of claim 15 , wherein the casing string is inserted into a hard rock mined cavern, wherein the casing string is cemented to the surface with gas block cement.
