A 'weld-done' finish - The Fabricator

  • Restoring The Hairline FinishThe Mirror FinishMaximizing Finishing EfficiencyGetting Around Corner WeldsWhen a hairline finish must be restored, use an elastic flap disk to remove the weld. One type of abrasive disk that does this is made from a compound developed specifically for grinding stainless steel. The fiber in the compound is derived from the hemp plant, which provides excellent abrasion while also being environmentally friendly. Heat absorbency is another characteristic of this material. When this type of abrasive flap disk is used on a variable-speed angle grinder at a maximum of 8,000 RPM, the grindinRa Surface Finish and Roughness Average - Northlake SteelNov 03, 2016 · Ra Surface Finish and Roughness Average November 3, 2016 by NSC Industry Resources news-press-releases Ra Surface Finish (Roughness Average) When measuring how smooth a turned, ground & polished (TGP), chrome plated hydraulic cylinder rod, or any other cold finished bar, the primary reading or parameter used is Ra surface finish.

    • IntroductionChemical CompositionMachiningWeldabilityHeat TreatmentForgingStress RelievingAnnealingNormalizingNitridingAISI 4140 is a chromium-molybdenum alloy steel. The chromium content provides good hardness penetration, and the molybdenum content ensures uniform hardness and high strength. AISI 4140 chrome-molybdenum steel can be oil hardened to a relatively high level of hardness. The desirable properties of the AISI 4140 include superior toughness, good ductility and good wear resistance in the quenched and tempered condition. The AISI 4140 cold finished annealed chromium-molybdenun alloy Industrial hand-held grinding and surface finishing &mdash Apr 13, 2010 · Stainless steel and nonferrous fabrications often have protruding weld seams and scratches after the initial fabrication. Very thick welds, if present, should be removed with a flap disk (Figure 1) before continuing with the steps to apply a brush, satin, or matte finish to these materials.

Stainless steel weld finishing by the numbersJul 07, 2014 · In some stainless steel applications, weld grinding is required as one of the last steps for finishing. As the demand for stainless steel increases, welders and metal fabricators need to understand how to obtain the proper finish. Standard mill finishes usually are applied to flat-rolled stainless steel directly by the manufacturer.Handbook:Everything You Should Know About 4140 SteelBefore 4140 steel is ready for use, it is usually subjected through these three processes; annealing hardening and tampering. The purpose of these processes is to enhance the physical and mechanical properties of this steel. 4140 steel is annealed at 872°C which is equivalent to 1600°F. After that, the steel is cooled in a furnace.
