Dab tsi yog a335 p5 tshuaj muaj pes tsawg leeg
Feb 06, 2026
A335 P5yog chromium-molybdenum alloy steel, uas nws cov tshuaj muaj pes tsawg leeg feem ntau suav nrog cov ntsiab lus xws li carbon (C), chromium (Cr), thiab molybdenum (Mo). Qhov sib ntxiv ntawm chromium thiab molybdenum txhim kho cov hlau siab -kub tsis kam thiab corrosion kuj.
A335 P5 siab- siab alloy steel kav yog dav siv nyob rau hauv siab - siab boilers nyob rau hauv kev lag luam xws li roj av, tshuaj, thiab lub hwj chim rau thauj high - kub thiab siab -pressure kua media. Hauv nuclear fais fab nroj tsuag, roj refineries, thiab tshuaj nroj tsuag, A335 P5 siab- siab alloy steel kav yog siv los ua ib feem tseem ceeb ntawm cov kav raj xa dej kom ntseeg tau tias muaj kev nyab xeeb thiab kev ruaj ntseg ntev ntawm cov kav dej.

- Cov pa roj carbon (C): 0.05% - 0.15%: Cov ntsiab lus carbon pab txhim kho lub zog thiab tawv ntawm cov hlau, tab sis cov ntsiab lus ntawm cov pa roj carbon ntau tuaj yeem cuam tshuam cov tawv nqaij.
- Manganese (Mn): 0.30% - 0.60%: Manganese txhim kho cov tawv tawv thiab lub zog ntawm cov hlau, thaum tseem txhim kho weldability.
- Silicon (Si): 0.50% - 1.00%: Silicon txhim kho lub zog thiab hardness ntawm cov hlau thiab tseem txhawb kev tiv thaiv tshav kub thiab oxidation tsis kam.
- Chromium (Cr): 4.00% - 6.00%: Chromium yog ib qho tseem ceeb alloying nyob rau hauv A335 P5 alloy kav, txhim kho corrosion kuj thiab siab -kub kev ua tau zoo.
- Molybdenum (Mo): 0.45% - 0.65%: Molybdenum txhim kho cov hlau alloy lub zog thiab nkag mus rau qhov kub thiab txias, pab txhawb kev txhim kho ntev - lub sij hawm kev cia siab.
- Phosphorus (P): Tsawg dua lossis sib npaug li 0.025%: Cov ntsiab lus phosphorus yuav tsum tau tswj hwm qis kom tiv thaiv brittleness.
- Sulfur (S): Tsawg dua los yog sib npaug li 0.025%: Sulfur kuj yog ib yam khoom uas yuav tsum tau tswj nruj me ntsis. Cov ntsiab lus sulfur ntau dhau yuav txo qhov weldability thiab toughness ntawm alloy.
A335 P5 Alloy Steel Seamless Yeeb Nkab Cov Txheej Txheem
1. Kub- dov (extruded seamless steel yeeb nkab): Round billet → cua sov → tho → peb - yob skew dov, nruam dov los yog extrusion → raj tshem tawm → sizing (los yog txo) → txias → straightening → hydrostatic test → flaw ware ware
2. Txias- kos (dov) seamless steel yeeb nkab: Round billet → cua sov → tho → taub hau → annealing → pickling → oiling (tooj liab plating) → multi-dhau txias txias (txias dov) → billet raj → tshav kub kho → straightening law → hydrostatic test ware
A335 P5 boiler tube Kev ua tau zoo:
Qhov kev ua tau zoo ntawm A335 P5 alloy steel yeeb nkab yog tsim tag nrho nyob ib ncig ntawm nws daim ntawv thov scenarios, feem ntau xav txog hauv qab no:
1. Zoo heev - qhov kub thiab txias tsis kam: Ntawm kev khiav hauj lwm kub ntawm ob peb puas degrees Celsius, cov pa roj carbon zoo tib yam softens sai, thiab nws lub zog txo qis. A335 P5, ua tsaug rau nws cov alloy reinforcement, muaj peev xwm tswj tau cov neeg kho tshuab muaj zog nyob rau hauv qhov kub thiab txias thiab tiv thaiv qhov tshwm sim qeeb thiab "creep" tshwm sim los ntawm lub sij hawm ntev - kev ntxhov siab thiab kub siab. Qhov no yog qhov tseem ceeb rau kev ua haujlwm ntev -lub sij hawm nyab xeeb.
2. Cov oxidation zoo heev thiab corrosion kuj: High - qhov kub thiab txias ib puag ncig feem ntau nrog oxidation (xws li huab cua) thiab corrosion los ntawm cov xov xwm tshwj xeeb (xws li sulfur- muaj cov roj flue). Cov ntsiab lus ntawm chromium txaus nyob rau hauv cov yeeb nkab steel tuaj yeem tsim kom muaj qhov ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom chromium oxide tiv thaiv zaj duab xis rau saum npoo, tiv thaiv kev tiv thaiv oxidation ntxiv thiab ua kom qeeb ntawm kev yaig ntawm qee yam xov xwm corrosive, ncua kev pab cuam lub neej ntawm cov kav dej.
3. Tej yam machinability thiab weldability: Txawm hais tias nws yog cov hlau alloy, A335 P5 cov khoom siv tau zoo heev hauv kev ua haujlwm kub (xws li cov yeeb nkab dabtsi yog khoov) thiab vuam. Tau kawg, qhov no yuav tsum tau ua raws li cov txheej txheem vuam tshwj xeeb, xaiv cov khoom siv vuam sib txuam, thiab ua kom tsim nyog preheating thiab tom qab- kev kho cua sov kom ntseeg tau tias kev ua haujlwm ntawm cov welded sib koom ua ke ntawm cov khoom siv hauv paus thiab kom tsis txhob muaj qhov tsis xws luag xws li tawg.
