H11 steel yog ib hom muaj zog thiab siab toughness kub ua hauj lwm pwm steel. Nws muaj cov cua sov ua haujlwm zoo thiab hardness thiab dav siv hauv kev tsim cov pwm zoo, pwm qhov chaw, thiab cov cuab yeej.
Yam ntxwv:
H11 kub ua haujlwm pwm hlau muaj cov khoom zoo, tshwj xeeb tshaj yog kev ua haujlwm zoo ntawm qhov kub thiab txias, thiab tuaj yeem tswj tau lub zog siab thiab tawv hauv qab 600 degree. H11 steel muaj qhov kub thiab txias tsis kam. Tsis tas li ntawd, H11 steel kuj muaj zoo toughness thiab weldability, ua rau nws yooj yim rau txheej txheem thiab txheej txheem.
Tshuaj muaj pes tsawg leeg:
H11 steel chemical muaj pes tsawg leeg: carbon (C) 0 33-0.43 feem pua, silicon (Si) 0.80-1.20 feem pua, manganese ( Mn) {{10}}. 4.50-5.50 feem pua , molybdenum (Mo) 1.
H11 Steel Lub cev muaj zog:
Qhov ceev: 7.8g / cm³
Thermal expansion coefficient: 11.5 x 10 ⁻⁶ / degree
Thermal conductivity: 33 W / m · K
Thermal conductivity: 29.5 W / (m · K)
Mechanical zog (45HRC):
Tensile zog: Ntau dua los yog sib npaug rau 1500 MPa
Yield zog: Ntau dua los yog sib npaug rau 1240 MPa
Elongation tus nqi: Ntau dua lossis sib npaug li 10 feem pua
Impact toughness: Ntau dua lossis sib npaug ntawm 12 J / cm²
Kev ceev faj txog kev kho cua sov:
Kev kho cua sov ntawm H11 kub ua haujlwm pwm hlau muaj plaub theem: annealing, normalizing, quenching, thiab tempering. Thaum lub sij hawm annealing txheej txheem, cov hlau yuav tsum tau rhuab mus rau 820 degree thiab maj mam txias rau chav tsev kub. Thaum lub sij hawm normalizing txheej txheem, cov hlau yuav tsum tau rhuab mus rau 1020 degree thiab ces txias rau chav tsev kub. Thaum lub sij hawm quenching txheej txheem, cov hlau yuav tsum tau rhuab mus rau 1020 degree thiab ces txias sai heev rau chav tsev kub. Thaum lub sij hawm tempering, cov hlau yuav tsum tau rhuab mus rau 600 degree thiab ces txias rau chav tsev kub.
Vim nws zoo heev kub tsis kam thiab hardness, H11 kub ua hauj lwm pwm hlau yog dav siv nyob rau hauv kev tsim cov pwm zoo, pwm qhov chaw, thiab cov cuab yeej, xws li extrusion pwm, stamping pwm, kub extrusion pwm, kub shear riam, txias extrusion pwm, precision stamping pwm, thiab lwm yam. Tsis tas li ntawd, H11 steel kuj tseem siv tau los tsim cov khoom kub kub hauv cov teb xws li oxidation furnaces, kho cua sov rauv, chav turbines, thiab aerospace.
