Microstructure-Texture-Mechanical Properties in Hot

Feb 16, 2016 · Deformation characteristic of centrifugal casting 25Mn steel was investigated by compression tests, and then processing maps were established. According to the deformation parameters identified from the established processing maps and hot ring rolling (HRR) process, the industrial test for the 25Mn ring blank was performed. Optical microscope (OM) and electron Shenzhen heat treatment, heat treatment processing, the Apr 14, 2014 · Su's heat treatment Co. Ltd. was founded in 1990, after decades of development, scale is continually expanding, now located in Pak Sha Road manhole town Baoan District Shenzhen City Bridge Second Industrial Zone No. 14, the factory covers an area of 3000 square meters, the main business is to take all the metal, alloy steel, beryllium copper, high speed steel, heat treatment cryogenic Small Diameter Seamless Steel Pipe - Permanent SteelJun 13, 2019 · In the outer diameter, steel pipe of 89 mm or less, 4 mm or more, can be collectively referred to as a small-diameter seamless steel pipe. The small-diameter cold-drawn seamless steel pipe is a circular, square, rectangular steel with a hollow section and no seam at the periphery.

Square Tube Production Process

Jun 17, 2019 · (8) The welded seams are all inspected by online continuous ultrasonic automatic injury inspection to ensure the non-destructive testing coverage of 100% spiral welds. If there is a defect, the alarm is automatically alarmed and sprayed, and the production worker adjusts the process parameters at any time to eliminate defects in time. Stainless Steel Automotive Vanes manufacturesIncrease the corrosion resistance of stainless steel with the carbon content decreases, and therefore, most of the lower carbon stainless steel volume, to a maximum of 1.2%, and some steel c (carbon content), and even less than 0.03% (e.g. 00Cr12 ). Stainless steel is the main alloying elements Cr (chromium), only when the Cr content reaches a certain value, there is corrosion resistance of Steel pipe knowledge---heat treatment processJun 17, 2019 · The heat treatment system is:steel bar annealing, wire annealing or 830-840 degree oil quenching. Heat treatment process parameters:1. Ordinary annealing:790-810 degrees heating, after the furnace is cooled to 650 degrees, air cooling - HB170-207 2.
