Tungsten Carbide VS HSS (1)

HSS (luv rau high-speed steel) yog cov khoom siv rau cov cuab yeej hlau txiav yav dhau los. Thaum tungsten carbide tau tsim, nws tau suav hais tias yog ib qho kev hloov pauv ncaj qha rau cov hlau nrawm nrog zoo toughness, zoo heev hnav tsis kam, thiab tsis tshua muaj siab hardness. Cemented carbide feem ntau muab piv rau cov hlau ceev ceev vim muaj kev siv zoo sib xws thiab siab hardness.

Kev ua haujlwm ntawm tungsten carbide

Tungsten carbide yog ib qho micron me me hlau carbide hmoov uas nyuaj rau yaj thiab muaj siab hardness. Lub binder yog tsim los ntawm cobalt, molybdenum, npib tsib xee, thiab lwm yam. Nws yog sintered ntawm qhov kub thiab txias. Tungsten carbide muaj cov ntsiab lus kub-kub carbide ntau dua li cov hlau kub ceev. Nws muaj HRC 75-80 thiab hnav tsis kam.

Qhov zoo ntawm tungsten carbide

1. Lub hardness liab ntawm tungsten carbide tuaj yeem ncav cuag 800-1000 ° C.

2. Kev txiav ceev ntawm carbide yog 4 mus rau 7 npaug ntawm cov hlau kub ceev. Txiav efficiency yog siab.

3. Kev pab lub neej ntawm cov pwm, ntsuas cov cuab yeej, thiab cov cuab yeej txiav ua los ntawm tungsten carbide yog 20 mus rau 150 npaug ntawm cov cuab yeej alloy hlau.

4. Carbide tuaj yeem txiav cov khoom nrog hardness ntawm 50 HRC.

Disadvantages ntawm tungsten carbide

Nws muaj qhov tsis muaj zog dabtsi yog khoov, tsis zoo toughness, siab brittleness, thiab tsis tshua muaj kev cuam tshuam tsis kam.

HSS Performance

HSS yog siab carbon siab alloy steel, uas yog cov cuab yeej steel nrog siab hardness, siab hnav tsis kam, thiab kub-resistant. Nyob rau hauv lub xeev ntawm quenching, hlau, chromium, ib nrab tungsten, thiab carbon nyob rau hauv high-ceev steel tsim ib tug tsis tshua muaj zog carbide, txhim kho cov hnav tsis kam ntawm cov hlau. Lwm ib nrab tungsten dissolves rau hauv lub matrix, ua rau cov liab hardness ntawm cov hlau mus rau 650 ° C.

Cov txiaj ntsig ntawm HSS

1. Zoo toughness, zoo heev toughness, ntse txiav ntug.

2. Cov khoom zoo sib xws, feem ntau yog siv los ua cov cuab yeej ua haujlwm me me.

Disadvantages ntawm HSS

Hardness, kev pab cuam lub neej thiab HRC tsawg dua tungsten carbide. Ntawm qhov kub ntawm 600 ° C los yog ntau tshaj 600 ° C, lub hardness ntawm high-speed steel yuav txo tau zoo heev thiab nws yuav siv tsis tau.
