摘要： A non-copper-plated solid wire for CO2 gas shielded arc welding. The non-copper-plated solid wire for CO2 gas shielded arc welding with excellent feedability ensures a reduced amount of generated spatters when welded at a relatively low current area, resulting from controlling the ten point average roughness (Rz) of the wire surface to 0.10 to 9.00 μm and the Vickers micro-hardness of the wire surface (Hv(1g)) to 125 to 310. Therefore, the welding operation can be carried out with a high efficiency to produce a weld of good quality.

摘要： A steel wire is coated with a ternary alloy of iron, zinc and aluminum on an outermost surface thereof. The ternary alloy contains 10 to 30 weight percent of aluminum. The steel wire is primarily used as material for springs. An Fe--Zn--Al ternary alloy coated steel wire production method includes immersing a steel wire in a zinc molten bath to plate the steel wire with zinc; immersing the zinc-plated steel wire in a zinc-aluminum molten bath to form a ternary alloy of iron, zinc, and aluminum on a surface of the steel wire; and removing an unsolidified zinc-aluminum layer depositing on an outer surface of the steel wire while being taken out of the zinc-aluminum molten bath to expose the ternary alloy on an outermost surface of the steel wire.

摘要： Steel wires and steel rods with excellent cold forging properties and used in a manufacture of various machine components, which have relatively high strengths, are disclosed. The steel wires are produced by maintaining a product (n×YS) of a yield strength (YS) and a work hardening coefficient (n) obtained by a tensile test of the steel wire within a range of 4.0-11.0 kgf/2, without a need of additional quenching and tempering treatments after cold forging. There is no need to perform heating for spheroidizing annealing for a long time, and it is possible to produce quenched and tempered steel wires having excellent cold forging properties by quenching and tempering treatments in a short period of time.
