High Carbon Spring Tempering Steel Wire ประเทศไทย

Hard pull spring steel wire: Also known as HDMB spring wire, it is a cost-effective choice for many general-purpose applications. The carbon content ranges from 0.45 to 0.85 percent. Since it is usually not heat-treated after drawing, it has high strength and medium toughness. It is available in a variety of diameters and is manufactured in accordance with ASTM A227 (uncoated finish) and ASTM A764 (galvanized finish).

Oil tempered spring steel wire: Also known as OTMB spring steel wire, it is an excellent general-purpose spring steel wire with improved performance compared to hard drawing. The carbon content ranges from 0.55 to 0.85 percent. After drawing, the oil-tempered wire rod is subjected to heat treatment and controlled cooling in an oil bath to increase its toughness while maintaining high tensile strength. This makes it particularly suitable for applications requiring high impact resistance or a large number of deflection cycles. Oil tempered spring steel wire is available in a variety of diameters and is manufactured in accordance with ASTM A229. This grade does not provide a galvanized finish.

Music spring high quality steel wire: Also known as music wire or piano wire, it is a very high quality steel wire suitable for demanding applications. The carbon content ranges from 0.70 to 1.00 percent. The music wire is heat treated after drawing to relieve stress and toughen the wire while maintaining high tensile strength. The strings are typically 0.250 inches or less in diameter and are manufactured in accordance with ASTM A228. It has a variety of surface treatments to choose from, such as bright, phosphate, tin and zinc.

① High reliabilityBlack annealed wire from material, thermalimperfection,cracking ,inspection to shipmentare managed by strict quality assurance systemso it has high relability. wire sezes 9,1011121314,15......and 26 gauge.

② Sleek maneuverabilityBlack annealed wire offers excellent flexibilityand softness through the process of oxygenfree annealing.And the black oiled wire isformed via the process of wire-drawing, annealand fuel oil injection. We can do it into straightcutting wire and also do according to customersspecial requirement.

③ Extensive useBlack Annealed Wire is deployed both inconstruction and in agriculture. Hence, in civiconstruction annealed wire, also known as"burnt wire' is used for iron setting. lnagriculture annealed wire is used for bailing hayMeantime black annealed wire is widely used astie wire or baling wire in buildinq, parks anddaily binding.

④ Excellent durabilityThe packaging is made of plastic film insideand woven bag outside or plastic film insideand hessian outside. Good packaging bettelprotect the service life of annealed wire.

Black Iron Wire Application

1. General purpose iron wire rope : used in various ranges.

2. Iron wire rope for elevator: it is used in elevator equipment carrying people and things in high-rise buildings. It is required to have a compact and soft structure and small structural elongation. It usually adopts 8-strand structure.

3. Aviation wire rope: it is used for aircraft aerial rope or operation aerial rope, which is required to have high fatigue performance and corrosion resistance.

4. Iron wire rope for petroleum: strong bearing capacity and corrosion resistance.

5. Iron wire rope for aerial cableway and cable car: it is used for air transportation track. With cable car as the means of transportation, the steel wire rope is required to have a large safety factor, corrosion resistance and smooth surface.

6. Hoisting wire rope: it is required that the wire rope has high tensile strength, good flexibility, no rotation, distortion fatigue resistance and no looseness.

7. Fishing wire rope: it is used for trawling, fixed net, rolling net, etc. it works in rivers, lakes and sea water environment.It is required to have good corrosion resistance and flexibility.

8. Iron wire rope for mine hoisting.

9. Iron wire rope for tape.

10. Balance wire rope.
