Helical steel spring and method

Abstract: This invention relates to a quenched and tempered ferrous alloy suitable for helical springs, such as used in automotive suspension systems. More particularly, it is directed to a hot-formed, oil-quenched and tempered helical spring formed of a ferrous alloy consisting essentially of, by weight, about 0.51 to 0.91 percent carbon, about 0.75 to 1.00 percent manganese, about 0.70 to 1.10 percent silicon, about 0.25 to 0.40 percent chromium, the remainder substantially iron and incidental impurities. In the formed and heat-treated condition, said springs are characterized by good resistance to load loss, good resilience, resistance to atmospheric corrosion, and good surface qualilty.

Process for the extraction of nickel,copper and cobalt from manganiferous ores

Abstract: A PROCESS FOR THE EXTRACTION OF NICKEL, COPPER AND COBALT FROM MANGANIFEROUS ORES, SUCH AS DEEP SEA NODULES, IN WHICH THE ORE IS ROASTED FROM ABOUT 700*F. TO ABOUT 1400*F. IN A REDUCING ATMOSPHERE. THE ORE IS COOLED UNDER NON-OXIDIZING CONDITIONS, AND LEACHED UNDER OXIDIZING CONDITIONS WITH AN AMMONIACAL-AMMONIUM CARBONATE SOLUTION COMPRISING ABOUT 55 TO 160 GRAMS PER LITER OF AMMONIA AND ABOUT 30 TO 120 GRAMS PER LITER OF CARBON DIOXIDE.

Bake hardenable vanadium containing steel and method thereof

Abstract: Rolled articles such as hot rolled or cold rolled and annealed sheet and/or strip include effective amounts of vanadium in low carbon steels to produce an improved bake hardenable product especially adapted for automotive use. The use of vanadium in the alloy steel chemistry controls bake hardenability, permits solution annealing at lower temperatures in its manufacturing sequence and specifies a composition range which is more easily cast within desired limits and causes less variation in final mechanical properties. Controlling the vanadium to carbon ratio to maintain a value of about 10 or greater also improves aging resistance.

Accelerated Corrosion Test for Aluminum-Zinc Alloy Coatings

Abstract: An electrochemically monitored etching method has been developed to enable accelerated service life testing of aluminum/zinc alloy coatings with a dendritic microstructure. The method invo...
