On the Baijian platform、 customers can complete the inspection process online from ordering services、 submitting commission information、 and finally paying the inspection fee、 without leaving the house. Next、 I will briefly introduce the testing standards and process of Baijia.net for eutectoid steel testing
eutectoid steel refers to carbon steel with an eutectoid composition containing 0.77% carbon. The steel slowly cools from the high-temperature austenite zone to 727 ℃、 forming a polygonal pearlite structure、 where ferrite and cementite are arranged in parallel in a sheet like manner. High quality carbon structural steel and carbon tool steel both contain this structure. Generally、 a high cooling rate reduces the interlayer spacing of pearlite、 which is beneficial for improving strength and hardness
Detection range of eutectoid steel
Hypoeutectoid steel、 hypereutectoid steel、 cast iron eutectoid steel、 normalized eutectoid steel、 spheroidized annealed eutectoid steel、 quenched eutectoid steel、 etc
Testing items for eutectoid steel
