Arctic Himart - DCT

Arctic Himart - DCT Process

Cryogenic treatment is the Ultra low temperature processing of tools/Components to enhance their desired metallurgical and structure properties.
The Process temperature is about -196 Deg. Centigrade.
Slowly cooling a Tools/ Components to Deep Cryogenic Temperature and soaking it at this low temperature for number of hours changes the steel microstructure.

Importance of Arctic Himart - DCT Treatment

Metallurgical changes resulting from Arctic Himart deep cryogenic seen via SEM/TEM/EBSD.

Complete the Austenite to martensite without embrittlement.
Precipitation of fine primary and secondary (eta) carbides.
Lattice phase change from face centric to body centric tetragonal.
Material grain refinement; edge and boundary diffusion.

Benefits of Arctic Himart - DCT Treatment

Deep low temp. process with easy maintenance.	Environment friendly technology	High degree of Automation	Improved Surface and cutting quality
Reduces abrasive and adhesive wear of forming surfaces and cutting edges.	Green Process- No poisonous gases and chemicals are used.	For increased efficiency and energy savings in the entire process cycle.	Promotes a more uniform micro-structure
Surfaces treated with ARCTIC-HIMART® can still be modified and repaired by welding, grinding or machining.	Reduced coefficient of friction.	Reduce the frequency and cost of tool remanufacture	Reduces catastrophic tool failures due to stress fracture.
Stress relieves to reduce inherent/residual stress caused by manufacture	Tooling and production costs reduces through significantly higher anti-wear surface quality that requires significantly less rework		Decrease in machine downtimes and corrective maintenance costs through low-maintenance
ARCTIC HIMART®: Increases the overall durability of the treated product
ARCTIC HIMART® for punching and forming: Greater productivity, efficiency, and process reliability with an optimized ecobalance
