Heat Treatment Oils

Heat treatment oils
The purpose of Heat treatment oils to satisfy mechanical performance and produce high-quality metal materials by heating and cooling metal materials under specific conditions.
Heat treatment oils based on mineral oil is generally used, and heat treatments such as tempering and quenching are performed. NTG Korea Co., Ltd. is the best producer of Heat treatment oils in Korea and supplies various high-performance heat treatment oils nationwide.
In particular, semi-hot Quenching oil and vacuum quenching oil have a high share in the automobile bearing industry, and the R&D and supply of new products cannot be estimated by our competitors.

Cold Quenching Oil

Type & No. Product Name Viscosity (mm2/s) Flash point (COC) Purpose and Characteristics
40℃ 100℃
Type 1 No. 2 H.S.Q K-1070HS 16.0±3.0 - 204 ㆍH is the highest and especially brings out the characteristics of quenching in carbon steel.
ㆍIt has economical feasibility as the viscosity is low and consumption is low when used long-term.
ㆍHas good and stable oxidation and significantly produces less sludge.
ㆍCan be used long-term due to immersion performance and good stability.
ㆍUsed for heat treatment of ball and roller bearings.
