3. Test: 100% UT & MT tested

4:we are a factory , this forging in our factory are 100% exported

 1: we purchase the steel ingot from well know and qualified steel mill in china

2:All our forgings forged ratio over 3:1 , and gurantee a full time normalize and anneal process to make sure the grain size and cleaness degree

3:we have a strick quality control system and complete management service system
