KANUC (THAILAND) CO., LTD.
Metal surface-hardening treatment for various types of molds and parts.

Heavy Duty Equipment and Mass Production Components.​

 

​What is KANUC processing

Basic and diffusion-grounded Kanuc treatment. No deformation or surface roughening. Cr-content in steel increases surface hardness.
 [Application] VANE, Vent pipes, Molds, SUS parts, Cutlery

カナック処理の最も基本的な処理で拡散層を主体とし変形、肌荒れが無く、鋼中のCr量により表面の硬さがアップ。
​【使用用途例】VANE・ベント管・成形金型・SUS部品・刃物

Features

No white layer (iron nitride) is formed.
 ・Easily weldable
 ・Free from chipping or stripping
 ・Excellent in heat checking resistance
 ・Composite treatment is possible
  
Uniformly treatable to complex shapes and into deep holes.  
Appropriate for hardening stainless steels.   
Suitable for increasing wear resistance of hard metals.  
Least dimensional change due to treatment.
Least surface roughening after treatment. 

特徴

■ 表層に脆い窒素化合物層(白層)が生成しにくい
■ クラックを進展させるカモメマークが生成しません
■ 比較的浅い硬化層(拡散層)になります
■ 面荒れをおこしにくい
■ 寸法変化量が小さい
■ 溶接時にボイド等の欠陥をおこしません
