Taw qhia rau High - Strength Wear - Resistant Steel Phaj

High - lub zog hnav - resistant steel daim hlau uas ua raws li ASTM (American Society for Testing and Materials), DIN (Deutsches Institut für Normung), thiab JIS (Japanese Industrial Standards) yog tsim los muab kev tiv thaiv zoo heev rau hnav thiab muaj zog txhua yam. Cov qauv no xyuas kom meej qhov zoo thiab kev ua tau zoo ntawm cov hlau phaj thoob plaws cov kev siv sib txawv thiab cov cheeb tsam.

ASTM Cov Qauv rau High - Strength Wear - Resistant Steel Phaj

ASTM A514/A514M

Cov txheej txheem no suav nrog high-yield - lub zog, quenched thiab tempered alloy steel daim hlau. Cov hlau phaj feem ntau yog siv rau hauv cov ntawv thov uas yuav tsum muaj lub zog siab thiab zoo toughness, xws li hauv cov khoom siv hnyav thiab cov qauv uas yuav tsum tau ua kom muaj kev cuam tshuam siab thiab abrasive quab yuam.

Cov tshuaj muaj pes tsawg leeg ntawm ASTM A514 / A514M steel daim hlau suav nrog cov khoom xws li carbon (C), manganese (Mn), silicon (Si), chromium (Cr), nickel (Ni), thiab molybdenum (Mo). Cov ntsiab lus alloying tshwj xeeb thiab lawv cov proportions yog ua tib zoo tswj kom ua tiav cov khoom siv tshuab uas xav tau. Piv txwv li, cov ntsiab lus carbon feem ntau yog nyob ntawm 0.12 - 0.21%, uas ua rau lub zog thiab lub zog ntawm cov hlau.

Hais txog cov khoom siv kho tshuab, cov hlau phaj no muaj qhov tsawg kawg nkaus lub zog ntawm ib ncig ntawm 690 MPa (100 ksi) thiab lub zog tensile xws li 760 - 895 MPa (110 - 130 ksi). Lub zog siab tso cai rau lawv dais hnyav, thiab cov quenched thiab tempered microstructure muab zoo toughness los tiv thaiv cracking thiab brittle puas.

ASTM A829 / A829M ASTM A829 / ASTM A829 / ASTM A829 / ASTM A829 / ASTM A829 / ASTM A829 / ASTM A829 / ASTM A829 / ASTM A829 / A829M / ASTM A829 / ASTM A829 / ASTM A829 / ASTM A829 / ASTM A829 / ASTM A829 / ASTM A829 / ASTM A829 / ASTM A829 / ASTM A829 / ASTM A829 / ASTM A829 / ASTM A829 / ASTM A829 / ASTM A829 / A829M / ASTM A829 / ASTM A829 / ASTM A829 / ASTM A829) thiab ASTM A829

Nws yog lwm tus qauv ASTM rau alloy steel daim hlau nrog lub zog siab thiab hnav - tsis kam. Cov phaj hlau no feem ntau siv rau hauv kev tsim khoom ntawm cov khoom siv tshuab, xws li lub zog, ncej, thiab hnav - daim hlau.

Cov ntsiab lus alloying hauv ASTM A829 / A829M steel daim hlau ua lub luag haujlwm tseem ceeb hauv kev txhim kho lawv cov hnav - tsis kam thiab cov khoom siv kho tshuab. Qhov sib ntxiv ntawm chromium thiab molybdenum pab tsim cov carbide nyuaj, uas txhim kho qhov tawv tawv thiab hnav - tsis kam. Cov khoom siv tshuab muaj xws li qhov tsawg kawg nkaus lub zog ntawm kwv yees li 550 MPa (80 ksi) thiab lub zog tensile ntawm kwv yees li 725 - 930 MPa (105 - 135 ksi).

DIN Standards rau High - Strength Wear - Resistant Steel Phaj

 

TIAB SA 17100

DIN 17100 standardizes structural steels thiab muab specifications rau lawv cov tshuaj muaj pes tsawg leeg thiab txhua yam khoom. Qee cov steels them los ntawm tus qauv no yog siv rau hauv cov ntawv thov uas yuav tsum tau hnav - tsis kam thiab siab zog, xws li hauv kev tsim kho vaj tse thiab kev txhawb nqa tshuab.

Cov tshuaj muaj pes tsawg leeg thiab cov khoom siv kho tshuab sib txawv nyob ntawm qib tshwj xeeb. Piv txwv li, ib qib twg yuav muaj cov ntsiab lus carbon ntawm ib ncig ntawm 0.2 - 0.3% kom ua tiav qhov sib npaug ntawm lub zog thiab weldability. Lub zog tawm los tuaj yeem nyob ntawm 235 - 355 MPa rau qib sib txawv, thiab lub zog tensile raug kho raws li qhov yuav tsum tau ua ntawm cov ntawv thov sib txawv.

JIS Standards for High - Strength Wear - Resistant Steel Phaj

 

JIS G4001

JIS G4001 standardizes carbon steels. Txawm hais tias nws tsuas yog tsom rau carbon steels, qee qib tuaj yeem hloov kho lossis alloyed kom ua tiav siab - lub zog thiab hnav - resistant zog. Cov hlau no tuaj yeem siv rau hauv cov ntawv thov uas tus nqi - hnav zoo - cov kev daws teeb meem uas xav tau, xws li hauv kev tsim cov tshuab ua liaj ua teb lossis qee cov khoom siv hluav taws xob ua haujlwm.

Cov tshuaj muaj pes tsawg leeg feem ntau muaj cov ntsiab lus carbon xws li 0.05 - 0.5% nyob ntawm qib. Cov khoom sib txawv raws li qhov sib txawv, nrog rau lub zog tawm los ntawm 205 - 355 MPa thiab lub zog tensile los ntawm 330 - 540 MPa. Alloying cov ntsiab lus tuaj yeem muab ntxiv los txhim kho qhov hnav-tiv taus thiab lwm yam khoom siv kho tshuab raws li cov kev cai tshwj xeeb ntawm daim ntawv thov.
