BAIJIAN - Material testing agency
Steel materials are composed of iron and carbon、 and carbon steel and cast iron are the most commonly used iron-based materials、 which are industrial iron-carbon alloy materials. The main elements of steel include silicon、 manganese、 sulfur、 phosphorus、 etc. in addition to iron and carbon. According to its chemical composition、 it can be divided into low-carbon steel、 medium carbon steel、 and high carbon steel. According to their usage、 they can be further divided into carbon structural steel and carbon tool steel. According to the quality of steel、 it can be divided into ordinary carbon steel and high-quality carbon steel. Below、 Baijian will introduce to you the knowledge about steel testing Steel testing items:
Chromium content testing、 nitrogen content testing、 flaw detection testing、 quality testing、 metallographic analysis、 material composition testing、 silicon manganese content testing、 hardness testing、 performance testing、 high-temperature oxidation testing、 impurity testing、 aging testing、 corrosion testing、 etc Steel performance testing:
Electrical performance: elastic modulus measurement、 expansion coefficient measurement、 magnetic property measurement、 density measurement、 resistivity measurement、 etc Chemical properties: atmospheric corrosion experiment、 full immersion、 intergranular corrosion experiment、 antioxidant performance experiment、 intergranular corrosion experiment、 etc Physical properties: magnetic properties、 density、 elastic modulus、 thermal expansion coefficient、 resistance value、 etc Impact: High and low temperature impact experiments、 multiple impact experiments、 etc Non destructive testing: magnetic testing、 radiographic testing、 specification and size testing、 ultrasonic testing、 surface defect testing、 etc Stretching: hardness index、 plasticity index、 high-temperature creep experiment、 etc
Function of testing report:
