A method for protecting a plurality of metal electrical poles and copper grounding from galvanic corrosion in corrosive soils includes electrically interconnecting the poles to a grounding grid and providing an impressed current anode for the cathodic protection of the grounding grid.

Method for protecting electrical poles and galvanized anchors from galvanic corrosion

A consolidated, fully dense, high yield strength, austenitic stainless steel and article produced therefrom having improved pitting resistance and a low sigma solvus temperature. The article is produced from nitrogen gas atomized prealloyed particles. The steel and article have a high nitrogen content for increased strength and corrosion resistance.

High strength, corrosion resistant austenitic stainless steel and

A low carbon plus nitrogen, free-machining, austenitic stainless steel having improved machinability and excellent corrosion resistance. The steel composition in weight percent is carbon plus nitrogen up to about 0.06, chromium 16 to 20, nickel 6 to 14, manganese up to 0.60, sulfur 0.15 to 0.50, silicon up to about 1, phosphorus up to about 0.20, molybdenum up to about 1 and balance iron.

Low carbon plus nitrogen free-machining austenitic stainless steels with

A free-machining, austenitic stainless steel having low carbon plus nitrogen contents in combination with manganese and sulfur additions. The steel may have silicon of 0.045 to 1.00 percent.

Corrosion-resistant, low-carbon plus nitrogen austenitic stainless

A resulfurized, chromium-nickel austenitic stainless steel having improved machinability resulting from low carbon and low nitrogen contents in combination with manganese and sulfur additions. The composition of the steel consists essentially of, in weight percent, carbon plus nitrogen total up to 0.065, preferably up to 0.040 or 0.056, chromium 16 to 30, preferably 17 to 19, nickel 5 to 26, preferably 6 to 14, sulfur 0.10 to 0.45, preferably 0.10 to 0.25, more preferably 0.25 to 0.45, manganese 0.75 to 2.0, silicon up to 1, phosphorus up to about 0.20, molybdenum up to 1.0 and copper up to 1.00, and balance iron and incidental impurities.

Low carbon plus nitrogen, free-machining austenitic stainless steel

A chromium-nickel-copper, age-hardenable martensitic stainless steel having improved machinability in the solution-treated and also in the age-hardened condition. The steel has carbon plus nitrogen up to 0.08%, preferably 0.05 or 0.035% for purposes of improved machinability.

Age-hardenable stainless steel having improved machinability

A chromium-nickel austenitic stainless steel having improved machinability resulting from low carbon and nitrogen contents, along with a high manganese to sulfur ratio. The composition of the steel consists essentially of, in weight percent, carbon plus nitrogen up to 0.060, preferably up to 0.049, and most preferred up to 0.032, chromium 16 to 30, preferred 17 to 19, nickel 5 to 26, preferred 6 to 14, sulfur 0.25 to 0.45, manganese over 2 to about 7 and at least about eight times the sulfur content, balance iron and incidental impurities.
