Detailed Description

Tungsten steel thimble

Tungsten steel thimble - made of tungsten steel, ground by precision equipment, with high hardness, strength, wear resistance, and excellent corrosion resistance.  At present, it is suitable for plastic moulds, lathes and grinders, and for tungsten steel electrode rod in photoelectric industry  

Physical properties of  

1 g/cm3 density: 14.5  

(2) the hardness of HRA: 91.5  

(3) Co content: 10%  

④ Grain size :1.0um  

⑤ Bending strength N/mm2:≥2800  

⑥ Thermal expansion coefficient 10-6/0c :4.9  

Modulus of elasticity GPa:525  

The production process  

Ingredients (according to the requirements of applicable selection of tungsten carbide powder + cobalt powder) to the mix - crushing - drying, sieving after forming agent and dry again to sieving mixture system, the mixed system, pressing - molding - Germany import vacuum suit low sintering sintering furnace - after sintered blank - test (nondestructive ultrasonic flaw detection) - blank dimensions accuracy test - cutting molding to coarse grinding, fine grinding  → polishing → inspection → packaging → storage  


(1) Due to the addition of tantalum carbide TaC with excellent wear resistance and TiC with excellent heat resistance and wear resistance, the alloy has high wear resistance, and its service life is more than 3 times that of SKH51 high-speed steel and 65Mn steel.  

② The size is accurate, the processing accuracy is high, the polishing finish reaches Ra≥0.012 mirror effect.  

③ Tungsten steel thimble has excellent corrosion resistance and no rust, can work in acid, alkaline environment, can greatly reduce the maintenance cost and maintenance time  


① Tungsten steel thimble is suitable for making plastic mold industry flat thimble, round thimble, supporting needle, standard thimble, non-standard thimble and other mold accessories.  

② Tungsten steel thimble is suitable for positioning wear-resisting parts on lathes and grinds.  

③ Tungsten steel thimble is suitable for making tungsten steel electrode rod in photoelectric industry
