Research shows that sub-zero processing of steels can improve various mechanical properties, including hardness and strength, wear resistance, and dimensional stability.
Sub-zero treatment is increasingly being applied in North America, Europe, Latin America and Asia. Study of the metallurgy of sub-zero treatment casts light upon its underlying mechanisms, the reasons why the process works well for certain alloys, and variations in prior research results.
Sub-zero treatment processes can be grouped into two broad categories that impact steel in the following ways:
During the hardening of steels, cold treatment completes the metallurgical phase transformation of austenite to martensite via quench and temper heat treatment.
In higher-alloy steels, cryotreatment at temperatures below -190 °F (-120 °C) creates conditions for the subsequent nucleation of very fine carbides.
This white paper:
Discusses sub-zero treatment as an approach

Delves into research on sub-zero treatment technology, safety, and cryogenic processing equipment
Offers information on less commonly known applications of sub-zero processing
