METHOD FOR MANUFACTURE OF END TOOL FROM STAINLESS STEEL Russian patent published in 1995 - IPC

Abstract RU 2049126 C1

FIELD: metallurgy. SUBSTANCE: method involves preliminary cooling tool working part ends made from hexagonal steel to liquid nitrogen temperature; deforming; bending and conducting bench work; tempering at 480-510 C for 25-60 min. Method allows wear-resistance and service life to be increased by 3-4 times, surface finish and corrosion resistance to be increased by 1-2 degrees as compared with standard tool. EFFECT: increased efficiency and improved quality tool. 10 cl, 1 dwg, 1 tbl
