ASTM A519 GR. 1020 Cold Rolled Seamless Steel Tube is low hardenability low tensile Carbon Steel Tube, which is one of the most commonly used steel pipes for general purpose applications worldwide. It offers excellent mechanical and chemical properties like high strength, ductility, weldability, and high corrosion resistance.
ASTM B637 UNS N07718 W.Nr.2.4668 API 6A 718 Inconel Two heat treatments are generally utilized for Inconel 718 Heat Resistant Alloys:Solution anneal at 1700-1850°F followed by rapid cooling, usually in water, plus precipitation hardening at 1325°F for 8 hours, furnace cool to 1150°F, hold at 1150°F for a total aging time of 18 hours, followed by air cooling.
Mar 22, 2019 · Heat treatment is applied following the last cold forming process. Subject to appropriate processing conditions, the increase in the residual stresses involved enables both forming and machining to a certain degree. Annealed:GBK(+A) The last Cold forming process is followed by annealing in a controlled atmosphere. Normalized:NBK(+N)
Cold Drawn Seamless Steel Pipe Production Needs Attention Compared with ordinary cold drawn steel pipe, cold drawn precision seamless steel pipe production increases the hot-rolled capillary pickling re-inspection process, mainly to ensure that there are no defects such as folding and crack on the outer surface of the capillary tube, and the inner surface is excluded from folding and severely scribed.
Cold drawn seamless steel pipe heat treatmentDate:2018-01-19 View:968 Tag:Cold drawn seamless steel pipe heat treatment. Cold drawing seamless pipe for precision mechanical structure, hydraulic equipment and good surface finish cold drawn or cold-rolled precision seamless steel tubes. High-precision drawing that diameter size accuracy (tolerance) strict, the outer surface finish, roundness, straightness, thickness uniformity is good.
Nov 18, 2020 · Analysis of quality defects on the inner and outer surface of high-precision cold drawn seamless steel pipe:Cold drawn seamless steel pipes have the characteristics of no oxide layer on the inner and outer walls, no leakage under high pressure, high precision, high finish, no deformation when cold bending, no cracks in flaring and flattening, and anti-rust treatment on the surface.

High Precision Cold Rolled Seamless Steel TubeHigh Precision Cold Rolled Seamless Steel Tube is used in automotive industry, and in the occasion where the high accuracy, brightness, cleanness of the tube are required. Main Features Inner and outer walls of tube have high accuracy. Excellent brightness. No oxidization after heat treatment; High cleanness inside tube. Quality Standards:
A precision cold rolled strip, slit to our specified thickness and width, is fed through a series of contoured roll stands. These progressively form the strip into tubular shape. The formed strip is then fed through the weld box, where a single torch fuses the edges together using a Tungsten Inert Gas (TIG) welding process.
