ASTM A335 High Pressure Steel Yeeb Nkab
Dec 04, 2025
Dab tsi yog A335 Khoom
ASTM A335 seamless steel yeeb nkab yog tus qauv tsim los ntawm American Society for Testing and Materials (ASTM) los tswj cov seamless ferritic alloy steel kav rau siab - kev pabcuam kub. Cov txheej txheem no suav nrog ntau qib, xws li P1, P2, P5, P9, P11, P22, P91, thiab lwm yam, txhua tus muaj cov tshuaj lom neeg tshwj xeeb thiab cov yam ntxwv ua haujlwm kom tau raws li qhov xav tau ntawm qhov sib txawv ntawm qhov kub thiab txias - siab. ASTM A335 seamless steel kav feem ntau yog siv rau hauv siab - kub thiab siab - cov kav dej siab hauv kev lag luam xws li kev tsim hluav taws xob thiab petrochemicals. Hauv kev lag luam hluav taws xob, lawv feem ntau ua haujlwm hauv cov khoom xws li boiler superheaters, reheaters, thiab cov kav dej loj. Cov Cheebtsam no yuav tsum tiv taus siab - qhov kub thiab siab - siab zog qhov cuam tshuam, yuav tsum tau tshwj xeeb siab - qhov kub thiab txias, oxidation tsis kam, thiab nkag los ntawm cov khoom siv yeeb nkab.

A335 Cr-Mo alloy steel yeeb nkab Mechanical Properties:
Kev kho cua sov Technology
Los ntawm cov txheej txheem zoo li tag nrho annealing, normalizing nrog tempering, residual kev ntxhov siab los ntawm kev ua yog tshem tawm thiab grain qauv yog refined. Cov kauj ruam tseem ceeb suav nrog:
Cua sov rau 900-950℃tom qab cua txias
Tempering ntawm 650-700 degree
Kev tswj nruj ntawm cov cua sov thiab cua txias
Kev soj ntsuam System
Txhua batch yuav tsum dhau:
Spectroscopic tsom xam los xyuas cov tshuaj muaj pes tsawg leeg
Tensile xeem rau mechanical zog
Ultrasonic / eddy kev kuaj tam sim no txhawm rau txheeb xyuas cov teeb meem sab hauv
Hydrostatic testing kom paub tseeb sealing kev ua tau zoo
Ntim thiab shipping
