A cold-rolled and heat treated steel sheet, has a composition comprising 0.1%≤C≤0.4%, 3.5%≤Mn≤8.0%, 0.1%≤Si≤1.5%, Al≤3%, Mo≤0.5%, Cr≤1%, Nb≤0.1%, Ti≤0.1%, V≤0.2%, B≤0.004%, 0.002%≤N≤0.013%, S≤0.003%, P≤0.015%. The structure consists of, in surface fraction: between 8 and 50% of retained austenite, at most 80% of intercritical ferrite, the ferrite grains, if any, having an average size of at most 1.5 μm, and at most 1% of cementite, the cementite particles having an average size lower than 50 nm, martensite and/or bainite.

The freezing point of a liquid in a chilled liquid containment system is decreased by the addition of a mixture of sodium nitrite and sodium nitrate. Solutions of nitrite/nitrate in a ratio of 1.0:1 to 3.0:1 at a concentration of at least 25% lowers the freezing point of water to as low as −33° C. or lower, permitting water to remain liquid well below its ambient freezing point and preventing pipes containing the nitrite/nitrate solution from bursting when exposed to subzero temperatures. This allows liquids to remain liquid at much lower temperatures than normal, allowing the circulation of the liquids at lower temperatures and protecting their containment systems from the damage that could occur when the liquids freeze into their solid state while within the containment systems.

Inorganic anions nitrate and nitrite influence metabolic rate and glucose homeostasis. Infusion of nitrite iv caused an acute drop in resting energy expenditure (oxygen consumption) and nitrate, when given perorally, caused a reduction in oxygen consumption during exercise and a depression of the increase in blood glucose observed after an oral glucose tolerance test. The doses of nitrate and nitrite did not cause any detectable change in methemoglobin levels of blood. Also, nitrate and nitrite did not alter lactate levels in blood. This discovery provides useful treatments to regulate the energy expenditure and glucose homeostasis of a mammal by administration of inorganic nitrite and/or nitrate.
