DIN 1.2842 Txias Ua Haujlwm Pwm Steel Bar

Khoom Description

1.2842 steel yog ib yam ntawm cov hlau tsis tshua muaj hlau uas muaj cov cuab yeej zoo dua qub dua li cov cuab yeej carbon steel. Nws tsuas yog kev lag luam hlau tsis muaj Ni thiab Cr cov ntsiab lus hauv cov cuab yeej hlau hlau. Nws muaj siab hardness thiab hnav tsis kam. Thaum lub sij hawm quenching, lub deformation yog me me thiab hardenability yog zoo. Vim tias muaj qee yam ntawm vanadium nyob rau hauv cov hlau, cov nplej tau ua kom zoo dua qub thiab txo qis superheat rhiab heev ntawm cov hlau. Nyob rau tib lub sijhawm, cov carbides me dua thiab sib npaug.

 

1.2842 Hlau Khoom

1.2842 cuab yeej steel yog txias ua hauj lwm tuag steel. Cov hlau yog yooj yim rau forge, annealing, zoo txheej txheem muaj peev xwm, toughness, harden muaj peev xwm yog tsawg, nrog ib tug muaj zog nyiam mus suppress kub rhiab heev thiab gelatinous nag lossis daus ntawm carbides nyob rau hauv Tuam Tshoj tau dav siv. Cov hlau piv rau cov cuab yeej carbon steel, thiab muaj qhov zoo hardness thiab hnav tsis kam, zoo punching peev xwm, quenching deformation yog me me, yuav tsum hardness 63HRC.

 

1.2842 steel daim ntaub ntawv:

 

①Suitable ua rau me me stamping tuag nrog thickness tsawg dua 6 hli

②Rau ua qhov seem tuag nrog cov khoom thickness tsawg dua 3 hli, qhov pom zoo hardness yog 58 ~ 62HRC thaum ua convex tuag thiab 60 ~ 64HRC thaum ua concave tuag.
