EN 2.4856 Khoom siv yog dab tsi?
EN 2.4856, feem ntau hu ua Alloy 625, yog npib tsib xee-raws li superalloy paub rau nws zoo heev corrosion kuj, siab - kub lub zog, thiab weldability. Nws yog tsim los ntawm npib tsib xee (58-67%), nrog rau cov nyiaj tseem ceeb ntawm chromium (20-23%), molybdenum (8-10%), thiab niobium (3.15-4.15%). Cov hlau no tau siv dav hauv qhov chaw huab cua, xws li hauv kev ua tshuaj lom neeg, aerospace, thiab marine industries, vim nws tsis kam oxidation, pitting, thiab crevice corrosion.
Qhov sib npaug ntawm EN 2.4856 yog dab tsi?
Qhov sib npaug ntawm EN 2.4856 (Alloy 625) hauv lwm cov qauv suav nrog:
ASTM B625 / UNS N06625: Kev lees paub dav dav hauv Asmeskas rau Alloy 625.
DIN 17744: German sib npaug.
JIS NCF 625: Japanese sib npaug rau tib yam khoom.
Cov khoom sib npaug no qhia cov tshuaj muaj pes tsawg leeg thiab cov khoom zoo sib xws rau kev siv hauv siab - kev nyuaj siab, siab - kev siv corrosion.
