This leads to heavy wear on the affected surfaces and significant material loss.With hardened and chromed surfaces ,basic wear resistance can be achieved, and byusing ultraplate coating the mandrel life will be multiplied several times.Products ParametersMaterialsAISI H13, X35CrMo V51 ,4CrMoSi V1,28NiCrMoV10 etc.Diameter80-600mmLengthmax to 20,000mmHardnessMeet the customers'requirementsSurface ProcessingChrome platingThreadingAvailable, phosphatingChrome platingAs per requirement,thickness 0.045-0.065mmProcessEBT + LF (VD) + ESRProperty testsMagnetic testing,Ultrasonic testing etc.Lead timeabout 45 daysDelivery conditionFinished machiningApplicationMPM, PQF and FQM mills,Assel Mills,Accu-roll mill, Push Bench, Pilger mill,continuous tube mill etcMarketIndia,Saudi Arab,Russia,Slovenia,Thailand,Vietnam etc.Production process:1) forging2) rough machining3)magnetic test4) heating treatment5) ultrasonic test6) finish machining7) chromium plating8)thread phosphating9) packageMandrel products show Mandrel workshop showCustomer Visit
