Ring-die Manufacture from China Scheme-- Ring-die
[Brief Introduction]
Ring-die is divided into two kinds according to the raw material type: one is Stainless Steel Ring-die[X46Cr13 / INOX (4Cr13)], the other is Alloy-Steel Ring-die [20CrNiMo(SAE-8620) or 20CrMnTi(20MnCr5)]
[Technical Specification]
Stainless Steel Ring-die: Material Type:X46Cr13 / INOX (4Cr13); Hardness: HRC55 -58(For wood pellet mill); HRC52 -55(For feed pellet mill);
Alloy-Steel Ring-die: Material Type: 20CrNiMo(SAE-8620) or 20CrMnTi(20MnCr5);Hardness: HRC60 -62(For wood pellet mill); HRC58-60(For feed pellet mill);
