KYORITSU GOKIN CO., LTD.KYORITSU GOKIN CO., LTD.https://www.everloy.co.jp
The company has been engaged in the manufacturing of cemented carbide tools and spray nozzles since its inauguration in 1938, and they have been enjoying the patronage of customers under trade name "EVERLOY". We hereby express our deepest thanks for your support and patronage.In the midst of such drastic changes in technical innovation, all company members will actively deal with new demands by our customers by exploiting our originality. We sincerely hope that you will continue, more than ever, to give your valuable instruction and advice to us.
INTRODUCTION

・
・
・・
・
・
The strength of cemented carbides may decrease as a result of the surface condition. Please use diamond wheels during final processing.During grinding of cemented carbides, powder dust may become airborne. If you draw in a great deal of the dust, your health will be at risk. Please utilize the exhaust system and wear protective equipment, such as protective mask, etc. In addition, if the dust adheres to your skin or enters your eyes, immediately wash with water.When grinding cemented carbides or braze materials, heavy metal elements are present in waste liquid. Therefore, please practice proper waste liquid treatment. When identical cemented carbide is re-grinded, please check for any fractures. Fractures may occur on cemented carbide materials or products due to marking by laser, electrical pen, etc. Please take care not to mark on stress areas. When electric discharge machining of cemented carbide materials, residual cracks may occur on the surface and incur strength degradation. Please spin off the cracks by grinding exactly according to need.In the case of blazing cemented carbide, if the temperature of brazing filler metal is higher or lower than the suitable temperature, defluxions or fractures may occur on cemented carbide materials.
(CIS) (1998) (JCTMA)
・ Notabilias are quoted matters of Cemented Carbide Tool Industrial Standard (CIS) handbook (1998).・ English sentences have not gained approval from Japan Cemented Carbide Tool Manufacturer's Association (JCTMA).
Remark
・
・
・
・
The characteristic of cemented carbide is extremely hard but it is also brittle. It may damage the cemented carbide by impact or forced constriction.The density of cemented carbide is extremely large. Please handle with care as a heavy load when the product size is large or excessive in quantity. The thermal expansion coefficient of cemented carbide is different from other metals. In the case of a higher (lower) operating temperature than the eminent design temperature, the shrinkage fit or cooling fit products may cause fractures.The corrosion from grinding liquid, lubrication fluid or other liquids may cause strength degradation of cemented carbide. Please take care the custody condition.

Hardness is increased when Co content is reduced. When the Co content is constant, hardness rises as the WC grain size becomes finer.
Up to a certain percentage, a higher Co content will increase the transverse rupture strength. Under the condition of constant Co content, finer WC grain size will result in a higher transverse rapture strength.
Lower Co content gives rise to a higher compressive strength. If the Co content remains constant, finer WC grain size raises the compressive strength.
Lower Co content gives to a higher young's modulus.
A larger content of Co increases fracture toughness value. When the Co constant stays constant, higher fracture toughness is achieved when the WC grain size is larger.
A larger content of Co increases impact strength. If the Co content is constant, larger WC grain size will result in higher impact strength.

Everloy selects the most suitable material for respective applications from the materials shown in the chart below. (A erroneous selection might engender breakage or wear-out in early stage.)
Select KD grade for general use and EF grade when a sharper edge is needed.
Select KD grade for general use and A10W to control the electrical discharge crack effect. Select WD20 grade to control corrosion when water is used as a processing fluid.Generally, H1 and EF05 offers the highest hardness and excellent abrasion resistance. When increased abrasion resistance is needed, select SS grade or EF01, but it must be handled with care.
Select KN20 for non-magnetic applications such as molding for forming magnetic fields. Select KN20 for mechanical seals and so on because it is highly corrosion-resistant and acid-resistant.
When processing pure iron, pure copper, and other highly reactive metals with tungsten carbide, select MC20 to suppress reactions.
Select KX01 when processing stainless steel and other metals with low thermal conductivity that tend to contribute to work-hardening.
There are several types of tips for press mold as follows ;Tips totally sintered to dimensions.Tips partially ground.Finished tips.For sintered chips, standard grinding allowance is 0.5 mm per side, however, in cases of designed various differently shaped holes in a die block, it is common for the block to be supplied with one or several holes left in it. (Liquid solution is passed through the hole for electric discharge machining process.)Furthermore, direct tapping is available.

These figures show the relation between the WEDM process and the WC grain size of cemented carbide. It is revealed that the smaller the WC grain size becomes, the lower TRS after WEDM results. This is probably because the finer the alloy grains become the thicker the layer deteriorates after the WEDM process gets and more microscopic cracks are produced.

KX01 is specially designed by taking into account the characteristics of stainless steel to extend lifetime of the mold. This effect is applied to not only stainless steel but also other material such as phosphor bronze and copper beryllium alloy.This material grade is suitable for usage which requires sharper edge because it has excellent hardness and transverse rupture strength by ultrafine grain WC (under 1 μm).
For stainless steel (stamping for cable teaminals, switch panels, HDD suspensions, etc.), For hard-to-machine materials (increasing life of punches for narrow-pitch connector terminals), etc.
Note

Suitable material grades for thick stainless parts are WD20 or ME40 because KX01 is developed for thinstainless parts.
