Armco's Nitronic 50

Ideal For Downhole Use —Literature Available

Few applications have more de- manding and at the same time sensitive material requirements than those encountered in down- hole petroleum exploration. How- ever, many manufacturers are finding Armco Nitronic 50 stain- less steel to offer the type of properties needed for dependable downhole service.

One such application involves instrumentation that is periodi- cally lowered down the well hole to measure temperature, depth, direction, and inclination during drilling. To protect the instru- ments package and permit lower- ing and raising, a housing must be provided. This housing must resist corrosive attack common to oil well environments, resist high compressive stresses, and have very low magnetic permeability to avoid interference with the magnetometer in the instrument package.

Type 316 stainless steel, con- sidered because of its good corro- sive resistance, doesn't meet all the other requirements, so many operators were forced to use more expensive copper-nickel alloys.

Now many are using Nitronic 50 stainless steel because of its ex- cellent performance at significant cost savings compared to the cop- per-nickel alloys. In addition to the cost advantages of Nitronic 50, the material is also nonmag- netic so there's no interference with the instrumentation.

Nitronic 50 stainless steel is said to provide a combination of corrosion resistance and strength not found in any other commer-

Types 316 and 316L, plus ap- proximately twice the yield strength at room temperature. It also has good mechanical proper- ties at both elevated and sub-zero temperatures.

North American Trailing

Asks Title XI For $16-Million Hopper Barge

North American Trailing Co., a subsidiary of Great Lakes In- ternational, Inc., 2122 York Road,

Oak Brook, 111. 60521, has applied for Title XI financing to aid in constructing a 281-foot, self-pro- pelled, suction hopper barge.

The barge, which is to be used in the coastwise, inland, and for- eign trade, will be equipped with two 3,000-horsepower diesel en- gines.

If approved, Title XI financing would cover $12,375,000 or 75 per- cent of the estimated actual cost of $16,500,000.

Southern Shipbuilding Corp.,

Slidell, La., is the builder of the vessel. Delivery is set for Sep- tember 30.
