17-7ph caij nplooj ntoos hlav hlau yog dab tsi?
17-7PH caij nplooj ntoos hlav hlauyog lub siab -lub zog, nag lossis daus- hardening stainless hlau (AISI 631) paub txog kev ua haujlwm qaug zog zoo, zoo corrosion kuj, thiab formability, ua rau nws zoo tagnrho rau cov springs thiab aerospace qhov chaw xav tau kev ua haujlwm siab ntawm qhov kub siab (txog 600℃F / 316 degree). Nws yog tsim nyob rau hauv ib tug mos mos mob (C) thiab ces muaj hnub nyoog- hardened (CH900) kom ua tau nws superior mechanical zog, muab ib tug sib npaug ntawm stainless hlau corrosion kuj nrog lub zog ntawm siab - carbon hlau.
Cov qauv dab tsi npog 17-7PH caij nplooj ntoos hlav hlau?
Cov qauv uas muaj xws li:
ASTM A313 / A693 (nyob ntawm daim ntawv khoom)
AMS 5528 / AWM 5529
UNS S17700
Ib txwm lees paub cov qauv siv raws li cov hlau loj thiab daim ntawv thov.
Dab tsi ntawm stainless hlau yog 17-7PH caij nplooj ntoos hlav hlau?
17-7PH caij nplooj ntoos hlav hlau yog ib nrab- austenitic nag lossis daus-hardening stainless hlau hlau.Tsis zoo li austenitic caij nplooj ntoos hlav xov hlau (xws li 302 lossis 304), 17-7PH ua tiav nws lub zog siab los ntawm kev txias thiab nag lossis daus hardening, tsis yog txias ua haujlwm.
