The present work is concerned with the 21-6-9 cryogenic steel. The mechanical and physical propertiesas well as the structure stability have been studied systematically from room temperature to liquid he-lium temperature. The 21-6-9 steel makes a feature of strengthening by N and improved cryogenic magnetic pro-perties by Mn. It shows a desirable combination of high strength, high toughness at 4K. and higherantiferromagnetic temperature T_N. T_N is between 130-143 K, depending on the different methods ofmeasurement....

The present work is concerned with the 21-6-9 cryogenic steel. The mechanical and physical propertiesas well as the structure stability have been studied systematically from room temperature to liquid he-lium temperature. The 21-6-9 steel makes a feature of strengthening by N and improved cryogenic magnetic pro-perties by Mn. It shows a desirable combination of high strength, high toughness at 4K. and higherantiferromagnetic temperature T_N. T_N is between 130-143 K, depending on the different methods ofmeasurement. It has excellent magnetic stability below T_N. It was found that the magnetic permeability is between 1.0019-1.0025 from 300 to 4K. Resultsof the work show that the strain induced martensite transformation occurs during heavy deformationfrom 83 to 4K. The lath martensites were identified by magnetic metallography, by thin filmtransmission electron microscopy and X-ray diffraction analysis to be of two types, i. e., hop ε-mar-tensite and boo a'martensite. No martensitic transformation took place during cooling.
