ASTM A335 P11 Yeeb Nkab
Khoom Txheej txheem cej luam
ASTM A335 P11 Yeeb Nkab yog seamless ferritic alloy steel yeeb nkab feem ntau siv hauv cov ntawv thov kub. Nws yog tsim rau dabtsi yog khoov, flanging, thiab zoo sib xws ua hauj lwm, thiab muaj zoo tensile, tawm los, thiab creep-rupture zog.
Specification
ASTM A335 P11 specification npog nominal phab ntsa thiab yam tsawg kawg nkaus phab ntsa seamless ferritic alloy-steel yeeb nkab npaj rau high-temperature kev pab cuam. Cov yeeb nkab yuav tsum tsim nyog rau kev khoov, flanging (vanstoning), thiab kev ua haujlwm zoo sib xws, thiab rau fusion vuam.
