1.2714 Forged Kub Ua Haujlwm Pwm Hlau Round Bar
Alloy tool steel with lower content of alloy elements. It is also the traditional hammer forging die steel. It has good toughness, strength and wear resistance, hardenability, and 300 * 300 * 400mm workpiece can be fully quenched. The utility model is suitable for producing large and medium-sized hammer forging dies (>400mm) nrog cov duab nyuaj thiab hnyav hnyav.

1, Feature:
1) Thaum tshav kub kub resistant hnav-resistant forged steel, zoo heev cuam tshuam tsis kam, nrog zoo hardness thiab zoo toughness.
2) Cov khoom sib xyaw muaj cov khoom siv zoo thiab muaj zog hardenability, thiab tuaj yeem ua rau cov hlau nrog cov ntu loj dua kom tau txais cov tawv tawv ntau dua.
3) Kev ua haujlwm zoo ntawm kev sib hloov kho qhov muag yog ua rau saum npoo ntawm cov pwm uas tsis tshua muaj nqi ntawm 90.
4) quenching thiab tempering kho, hardness ntawm 52 ~ 62HRC (pre hardening),
5) tuaj yeem siv ncaj qha tom qab ua haujlwm txias rau hauv pwm, xyuas kom meej tias kev siv pwm ua haujlwm, tab sis kuj yuav tsum tsis txhob muaj kev kho cua sov los ntawm kev deformation ntawm pwm.

3, Txheej Txheem: EAF ntxiv rau LF ntxiv rau VD ntxiv rau Forged ntxiv rau Kev Kho Kub Kub (yeem)
4, Kev Them Nyiaj: 30 feem pua ua ntej los ntawm T / T; Qhov nyiaj tshuav them ua ntej xa khoom tawm tsam cov ntaub ntawv xa khoom lossis tsis tuaj yeem thim rov qab LC thaum pom.
5, Kev xa khoom: Rau cov khoom lag luam ntau, 7-15 hnub.For customized khoom, 15-30 hnub.
Daim ntawv thov
1.Die sheet khoom yog tsim rau forging xovxwm tuag, concave thiab convex tuag, tuag casting tuag, kub hlau cutter thiab lwm yam industries.
2.Aluminium alloy tuag casting tuag rau ntau lawm.
Peb Qhov Kev Pabcuam
A. Hlau daim hlau: Txiav los ntawm bandsaw tshuab, milling, kho cua sov, thiab lwm yam
B. Round tuav: txiav los ntawm bandsaw tshuab, tev, sib tsoo thiab tig, kho cua sov, thiab lwm yam
C. Ultrasonic kuaj thiab hardness kuaj
