MRC’s new HNRC steel bearings are constructed from high nitrogen corrosion resistant steel and offer improved corrosion resistance and fatigue life compared with stainless steel. Bearings can be custom-engineered to meet particular application requirements. Applications include food processing equipment, paper mill machinery and industrial pumps. According to the company’s press release, the presence of nitrogen coupled with high chromium in HNCR steel in these bearings contributes to the improvement in corrosion resistance compared with 440C stainless. Hardened and tempered HNCR provides hardness comparable to 52100 steel and HNCR steel yields fatigue life better than 52100.
