Hardness thiab Mechanical Properties ntawm A335 P5 Khoom

Dab tsi yog A335 P5 Khoom

A335 P5 alloy steel yeeb nkab yog seamless chromium -molybdenum alloy steel yeeb nkab rau ASME SA335 / ASTM A335. Nws yog tsuas yog siv nyob rau hauv cov khoom xws li economizers thiab superheaters nyob rau hauv siab - siab boilers thiab cua sov nto raj nyob rau hauv qis - thiab nruab nrab- siab boilers, thiab kuj yog dav siv nyob rau hauv siab - kub thiab corrosive kev pab cuam ib puag ncig xws li boilers, tshav kub exchangers, fais fab nroj tsuag, thiab petrochemical systems. 5Cr-0.5Mo chemistry muab oxidation tsis kam thiab creep zog ntawm qhov kub thiab txias.

Main Mechanical Properties

Rau lub hom phiaj tsim, qhov tsawg kawg nkaus qhov tseem ceeb ntawm ASTM A335 specification tswj: yam tsawg kawg nkaus tensile zog 415 MPa thiab yam tsawg kawg nkaus yield zog 205 MPa nyob rau hauv lub annealed mob.

Kev tsim thiab Fabrication

A335 P5 alloy steel yeeb nkab yog tsim los siv cov txheej txheem kub dov lossis txias txheej txheem thiab muaj ntau qhov ntau thiab tsawg. Cov yeeb nkab yuav tsum tau kho cua sov, muaj kev ua haujlwm zoo, thiab tsim nyog rau kev khoov, flanging, vuam, thiab machining. Vuam yuav tsum tau preheat thiab tom qab-weld heat treatment raws li txoj cai siv vim yog hardenable chromium-molybdenum chemistry.

Nta

1. High-kub lub zog: cov khoom tuav lub zog siab thiab toughness ntawm qhov kub thiab txias, ua kom nws tiv taus siab - kub thiab siab - qhov chaw ua haujlwm siab.

2. Zoo corrosion kuj: nws resists yaig ntawm ntau yam acids, alkalis, thiab ntsev nyob rau hauv hnyav industrial puag ncig.

3. Zoo weldability: nws tuaj yeem txuas thiab kho los ntawm ntau txoj kev vuam nrog cov txheej txheem tswj kom raug.

4. Cov khoom siv kho tshuab zoo heev: lub zog txhua yam muaj zog thiab hardness, nrog kev qaug zog zoo thiab cuam tshuam tsis kam.

Daim ntawv thov

Vim nws zoo heev - kub thiab siab - kev ua haujlwm siab, A335 P5 feem ntau yog siv nyob rau hauv peb qhov chaw tseem ceeb: kev lag luam petrochemical (siab-kub sib txuas kab hauv hydrotreating thiab hydrogenation units), kev lag luam hluav taws xob (lub ntsiab chav thiab siab -kub reheater piping6}), thiab kev lag luam kub siab kav dej). Hauv cov kev pabcuam no, cov hlau kub tuaj yeem ncav cuag li 550-650 deg C nyob ntawm tus qauv tsim.

Ordering Information

Orders yuav tsum qhia tag nrho: kom muaj nuj nqis; khoom npe; qib; txoj kev tsim khoom (kub-kos lossis txias-kos); qhov ntev (NPS lossis sab nraud thiab phab ntsa thickness); ntev; kawg ua tiav; thiab xaiv cov kev cai xws li kev sim hydrostatic thiab kev tso cai qhov hnyav ntawm ASTM A530.
