Qhov kev qhia tshwj xeeb no npog cov npoo ncaj los yog muab kauv npoo hluav taws xob-fusion-welded, lub teeb ntsa, phab ntsa, austenitic chromium-nickel alloy steel yeeb rau kev xeb lossis siab kub. Qhov ntau thiab tsawg npog yog NPS 14 txog 30 nrog lub teeb ci ntxiv (Daim Sij Hawm 5S) thiab lub teeb (Teem 10S) phab ntsa tuab. Cov lus X1 qhia cov phab ntsa tuab ntawm Cov Sij Hawm 5S thiab10S yeeb nkab. Cov yeeb nkab uas muaj lwm qhov ntev me me tuaj yeem muab txhais tau tias yog cov yeeb nkab raws li txhua lwm cov cai ntawm qhov kev ntsuas no.

A. Kev Kho Thaum Tshav Kub Kub:

1. Tshwj tsis yog raws li hauv "point A.2", tag nrho cov kav dej yuav tsum tau muab ntim hauv qhov kub tau kho. Rau qib H thiab S30815, nyias muaj nyias cov kev kho cua sov kom ua rau kev daws teebmeem; Cov txheej txheem kev kho cua sov tsis raug tso cai ua qhov hloov pauv rau kev kho cua sov sib cais.

Cov txheej txheem kev kho cua sov muaj xws li cua sov rau cov khoom kom kub yam tsawg kawg 1900 ° F [1040 ° C], tshwj tsis yog S31254, S31266, thiab S30815 uas yuav tsum tau kho kub kom2100 ° F [1150 ° C] thiab 1920 ° F [ 1050 ° C] feem, S31727 thiab S32053 uas yuav tsum tau kho kub kom sov hauv thaj tsam 1975 txog 2155 ° F [1080 txog 1180 ° C], S34565which yuav tsum kho cua sov hauv thaj tsam 2050 ° F [1120 ° C] txog 2140 ° F [1170 ° C], thiab N08367, uas yuav tsum muab rhaub kom kub li tsawg kawg 2025 ° F [1107 ° C], txhua cov ntaub ntawv yuav tsum tau txuas ntxiv los ntawm quenching hauv dej lossis nrawm txias los ntawm lwm txoj kev.

2. Daim ntawv xaj yuav khoom yuav tsum qhia cov cua kub kawg rau kev tiv thaiv kub li 1900 ° F [1040 ° C].Txhua cov yeeb nkab uas siv raws li qhov yuav tsum tau no yuav tsum tau ua kom sov nrog rau qhov ntsuas kub kom sov nyob rau hauv degrees Fahrenheit lossis degrees Celsius tom qab cov lus kawg "HT." Kev tswj cov txheej txheem lossis cov kev pabcuam tshwj xeeb uas tej zaum tau hais ua qauv qhia ua kev kho cua sov tshaj plaws

3. Ib qho kev daws teeb meem rau qhov kub thiab txias siab tshaj 1950 ° F [1065 ° C] yuav ua rau qhov tsis kam tiv thaiv qhov kev cuam tshuam tom qab tom qab kis tau ntawm qhov kev xav ntawm TP321, TP347, thiab TP348. Thaum sau tseg los ntawm tus yuav khoom, qis kub kom ruaj khov lossis rov hais daws anneal yuav tsum tau siv tom qab tothe pib high-temperature tov anneal.
