#steel

• Refining — An industrial technological process or set of physico-chemical operations performed to eliminate impurities from a raw metal, alloy, or molten glass; refining. In steelmaking, it specifically designates the conversion of pig iron into steel by reducing carbon, sulfur, and phosphorus.
• Refining — A complex industrial technological process consisting of removing impurities, trapped gases, or residual elements from raw materials to increase purity and homogeneity. It applies to clarifying molten glass, purifying metals (pig iron into steel), and refining raw sugar before bleaching.
• Bluing — The act of turning blue and its result; the process of coloring, dyeing, or impregnating a material or surface with blue. In metallurgy and mechanics, it represents the thermal surface treatment applied to steel parts to increase their corrosion resistance and provide them with a protective azure film. In medicine, it indicates the appearance of cyanosis or a bluish tint in the skin or mucous membranes due to insufficient oxygenation of structural blood.
• Alloy — A metallic product obtained by melting and solidifying a mixture of two or more metals or metals and non-metals. In metallurgy and materials engineering, it describes homogeneous macrostructural compounds designed to acquire physical-chemical properties superior to those of pure elements.
• Shot — Small spherical projectiles, typically manufactured from lead, steel, or other heavy metal alloys, used as a multiple payload inside cartridges designed for smoothbore hunting shotguns. This type of ammunition is structurally engineered to disperse into a compact cluster upon exiting the barrel, increasing the probability of hitting fast-moving targets by creating a geometrically distributed impact pattern.
• Shot-peened — Having undergone the process of shot-peening or shot-blasting; a metallic object, structural part, or hard surface treated by continuous bombardment with a stream of metallic pellets. In a technical sense, it describes the final state of a strain-hardened material whose surface micro-imperfections have been eliminated and whose internal compressive stresses have been industrially optimized to resist chronic fatigue and cracking.
• Aluminizing — A thermochemical surface treatment process applied to steel or iron parts, consisting of saturating the surface layer with aluminum via diffusion at high temperatures to enhance heat and corrosion resistance.
• Aloțel — A popular, regional, or archaic diminutive form used in the traditional language of craftsmen to designate a small fragment of steel, a small tool made of a hard ferrous alloy, or a thin soft steel wire. In the structural ethnographic context, the term reflects the metaphorical or descriptive designations used in old ironmongery and blacksmith workshops.
• Fire steel — A small piece of hardened steel, varying in shape, historically used in households to strike sparks from a flint stone in order to ignite tinder or tinderbox sulfur. Figuratively, regionally, or archaically, the term can describe a mechanical support or an iron hook used in traditional wagons.
• Archaic fire steel — An old archaic spelling variant or regional form for 'amânar' (fire steel); a small piece of hardened steel historically used to strike sparks from a flint stone to start fires. In medieval manuscripts, it can also refer to an iron mechanical support or structural link.
• Fire steel — A small steel tool, often curved in the shape of a link or blade, used in the past, by striking it against a piece of flint (cremene), to produce sparks capable of igniting tinder or cotton. In an archaic and ethnographic sense, the piece represents a basic element of the traditional Romanian household, symbolizing the ritualistic lighting of fire, and in an extended technical sense, it can designate the central axle or supporting beam of a water or wind mill.
• Small fire steel — A rare diminutive of the noun 'amnar', designating a small-sized fire steel, often used by travelers, hunters, or shepherds for easy carrying in small belt pouches. In an extended structural sense, the term can also describe a small metallic piece or a secondary axle within a traditional watermill mechanism or household tool.
• To strike fire — To strike the steel against flint to produce sparks for the purpose of lighting a fire; to spark using a fire steel. In a figurative or regional sense, the action can describe a structural tightening process, a sharp verbal confrontation from which 'sparks fly', or the intense effort to generate a saving idea in a critical situation.
• Fire-striking — The act of striking fire with steel and its result; the traditional physical process of repeatedly striking a fire steel against a flint stone to produce sparks and ignite tinder. Figuratively, the term describes a structural tightening of relations between two people, manifested through sharp remarks and verbal hostility.
• Small fire steel — A regional diminutive form of 'amnar', designating a very small-sized fire steel, traditionally used by shepherds or hunters to be carried discreetly in special boxes or leather pouches fastened at the belt. In an archaic technical sense, it can also name a small bolt, pin, or metallic pivot used as a structural connecting or adjusting piece within a peasant mill assembly.
• Passivated — Having undergone the process of passivation or surface treatment; a material, alloy, or mechanical component structurally protected through a thermochemical or chemical surface treatment. In an industrial sense, it describes the final state of a precision part whose physical properties have been optimized to resist the action of acids, moisture, or mechanical abrasive wear.
• Diaphragm girder — A secondary horizontal beam, rigid connecting piece, or structural stiffening element mounted transversally between two parallel main girders, aiming to maintain their distance constant, prevent their twisting or buckling, and uniformly distribute gravitational or dynamic loads. This element is essential in the construction of steel bridges, viaducts, and complex roof frameworks.
• Reinforcement — The act of arming or reinforcing and its result; the insertion of steel, fiber, or other resistant reinforcement bars into a structural element (such as concrete) to increase its tensile strength. In a military or mechanical sense, it represents the cocking or prepping of a firearm, device, or trigger mechanism by tensioning internal springs to make it operational.
• Reinforcement — An assembly of metal parts (steel bars, meshes) embedded in a construction element to increase its tensile or bending strength; the totality of auxiliary devices (valves, cocks) attached to a pipe or boiler for fluid control; the moving metal part of an electromagnetic apparatus or the protective sheath of a cable.
• Reinforcements — The totality of metallic parts or elements (steel bars, welded meshes, profiles) structurally embedded in concrete to absorb tensile and bending stresses, creating reinforced concrete. In an extended technical sense, the term designates the assembly of auxiliary safety, control, and regulation devices (valves, faucets, pressure gauges) mounted on a pipeline, boiler, or industrial system, serving to ensure the optimal operation of the installation.
