Rau cov pa roj carbon zoo li O-1 uas yog li 200 degrees Celsius. Rau lwm hom hlau xws li HSS yog annealed siab tshaj 500 degrees Celsius.
Qhov kub ntawm cov hlau kub li cas?
Tempering yog siv los txhim kho toughness nyob rau hauv cov hlau uas tau dhau los ntawm hardened los ntawm cua sov nws los ua austenite thiab ces quenching nws los ua martensite. Thaum lub sij hawm tempering cov hlau yog rhuab mus rau ib tug kub ntawm 125 ° C (255 ° F) thiab 700 ° C (1, 292 ° F).
Qhov kub ntawm cov hlau tawv tawv poob nws qhov tawv?
Los ntawm 300 txog 680 ° C, qhov nyuaj ntawm cov hlau txo qis thiab qhov cuam tshuam toughness nce nrog nce tempering kub, thaum lub thib ob hardening nrog siab tshaj plaws hardness, 48.6 HRC, yog tiav. ntawm 550°C.
Yuav tau tempered steel tawg?
Txhaj Tempering Strength
Cov khoom siv tawv, piv txwv li, tiv thaiv kev puas tsuaj thiab kev sib txhuam, tab sis nws tseem tuaj yeem tawg thiab txawm tawg. Lub zog tensile yog lub hom phiaj, tom qab ntawd, nrog rau theem tempering relieving lub steel ib feem lub quench-crapped brittleness xeev.
Puas yog tempered steel muaj zog dua li cov hlau tsis tu ncua?
Thaum tempered steel yog, qhov tseeb, ib qho hlau alloy, nws tseem muaj cov hlau thiab carbon zoo tib yam li cov hlau. Txawm li cas los xij, tempered steel muab qib siab ntawm lub zog, ua rau nws nyiam rau qee yam kev tsim khoom.
