Manufacturing high-carbon metal wire rod

The current invention additionally provides use of the high-carbon metal wire rod for producing 2300MPa stage pre-stressed metal wire, 2300MPa degree pre-confused steel strand, or 1960MPa degree bridge cable zinc-coated metal wire. In 2018, the<!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}-->pc strand demand in Japan amounted to approximately 2,one hundred seventy five tons, a lower from about 4,416 tons in 2012. Carbon steel has excessive hardness, toughness and strength, and it's relatively inexpensive in comparison with different steels. four.

A way of manufacturing high-carbon metal wire rod wonderful in drawability based on declare three whereby the starting slab additional contains Cr: 0.10-zero.30% as an alloying component. Carbon metal wire is available in diameters that vary from 0.008” to 1.25” depending on the type.

The excessive-carbon steel wire rod has good resistance to breakage and contributes to prolonged die life. In accordance with the current invention, the high-carbon steel wire rod should have a particular construction (which pertains to drawability and die life) as defined within the following. Amongst them, a excessive carbon chromium bearing metal (SUJ materials) defined by JIS G 4805” is usually used as a bearing material.

Mainly used for wire drawing, cold drawn or chilly rolled metal wires. The breakage resistance was rated in accordance with whether or not or not 100 tons of wire rod broke during drawing. With ISI certification, our provided collection of Wire Rods is extremely appreciated for sturdiness and effectivity at cheap costs. 2. The high-carbon steel wire rod as outlined in declare 1, whereby the chemical composition moreover has both or both of the next parts: Nb: zero.020-0.050% V: 0.05-zero.20%.

For instance, SWRH 37A, SWRH 37B, SWRH 42A and SWRH 42B are laborious steel wire that contain zero.four% carbon. Meanwhile, Mo is ready to cut back the possibility of community cementite current on the grain boundaries, which is useful for growing the plasticity of the high-carbon steel wire rod. Manganese (Mn) ingredient is beneficial as a deoxidizer, as with Si; successfully contributes to larger strengths of the wire rod; and, in addition, fixes sulfur within the metal as manganese sulfide MnS to forestall hot embrittlement.

By contrast, with a content greater than 1.zero%, carbon provides rise to pro-eutectoid cementite, which deteriorates drawability. Pearlite texture forms on the wire rod or wire heart portion in a pearlite wire rod or wire handled at a isothermal transformation temperature exceeding 500° C. Since pearlite texture has a laminar construction of cementite and ferrite, it makes a serious contribution to work hardening, however a decrease in ductility cannot be prevented.
