Ring Plunger Set By Shree Gayatrikrupa Engineering

Ring Plunger- Set RP set is manufactured from nitro alloy (EN-41B) material which is available in Indian as well as Imported make. The material is toughened in raw condition that is 'S' or 'T' condition up to 30/32 RC which gives hardness to the material. Then after machining to be done as per required dimension of outer layer and keep 0.5mm on core diameter and 1 mm on dia. There are stresses development while machining that is to be relieved known as stress relieving, the base hardness is reduced by 2 RC maximum. After toughening final machining to be done to get required dimension and do outer and inner diameter grinding and do the nitride hardening to get surface hardness up to 64/66 RC by gas nitriding process and case depth up to 0.5/0.6 mm deep to run longer time.
