Product Desciption
Cold finished bright square/hexgonal/flat/section steel bar
SAE1018 SS400 cold draw bright hexgonal steel
Brife introduction of cold finished/cold drawn steel
Raw Stock: Hot rolled steel bar or rod coils are used as raw material. Because the hot rolled products are produced at elevated temperatures (1700 - 2200 Deg. F. i.e. hot rolling), they generally have a rough and scaled surface and may also exhibit variations in section and size.
Cleaning: Abrasive scale (iron oxide) on the surface of the hot rolled rough stock is removed.
Coating: The surface of the bar or coil is coated with a drawing lubricant to aid cold drawing.
Drawing: In this process, the material being drawn is at room temperature (i.e. Cold-Drawn). The pointed/reduced end of the bar or coil, which is smaller than the die opening, is passed through the die where it enters a gripping device of the drawing machine. The drawing machine pulls or draws the remaining unreduced section of the bar or coil through the die. The die reduces the cross section of the original bar or coil, shapes the profile of the product and increases the length of the original product.
Finished Product: The drawn product, which is referred to as Cold Drawn or Cold Finished, exhibits a bright and/or polished finish, increased mechanical properties, improved machining characteristics and precise and uniform dimensional tolerances.
1.Our cold drawn steel bar main type and avaliable sizes
1215,12L14,SAE1018, 1020,A36,SS400 mild steel -- A low carbon steel with a medium manganese content. Has good hardening properties, fair machinability. Readily grazed and welded. Suitable for shafting and for applications that do not require the greater strength of high carbon and alloy steels. Conforms to ASTM A-108 and AMS 5069.
Medium Carbon - Direct Hardening
SAE1040, 1045,1035 carbon steel-- Medium carbon steels used when greater strength and hardness is desired in the as-rolled condition. Can be hammer forged and responds to heat treatment. Suitable for flame and induction hardening. Uses include gears, shafts, axles, bolts and studs, machine parts, etc.
Medium Carbon Alloy Bars -- Direct Hardening
SAE8620 STEEL BAR-The medium carbon and direct hardening steels in this group offer you the right combination of strength, toughness and hardness after oil quenching and tempering -- plus machinability. When increased wear resistance is required in localized areas, they can be flame or induction hardened. Hardenability data is developed for each heat of steel and furnished with the heat's certification document.
Scm420/4130/4140/4150 -- are widely used medium carbon steels -- truly general purpose alloys, low in cost. Nominal composition: .95% chromium and .20% molybdenum content. A broad range of strength and toughness is attainable through variations in heat treatment. Good hardenability, strength, wear resistance, toughness and ductility.
