The behavior of decarburization sensitivity and oxidation weight loss of three medium carbon spring steels; 0.49C-0.29Si- 1.65Mn
0.53C-0.78Si- 1.56Mn and 0.54C- 1.74Si-0.71Mn(6Si2MnA)heat-treated at 850 ℃ for 5~120 min
water cooling
and at 780~1000℃ for 60 min water cooling has been tested and studied. Results showed that with increasing silicon content in steel
the decarburization depth increased and the weight loss of oxidation decreased. It indi- cates that Si can increase coefficient of diffusion of carbon in steel to improve decarburization of steel.
