AISI Qib

AISI steel specifications tau tsim los ntawm American Iron And Steel Institute. Cov qib AISI tau tsim nyob ib puag ncig tib lub sijhawm raws li qib SAE, thiab vim lawv qhov zoo sib xws, thaum kawg tau muab tso ua ke rau hauv kev hloov pauv AISI / SAE. SAE thiab AISI ib zaug tau sib tw rau kev tswj hwm ntawm North American Steel kev lag luam, tab sis AISI specifications tau tam sim no yuav luag tag nrho los ntawm SAE.

BS EN Standard Qib

BS EN steel specifications tau qhia los ntawm British Standards Institute thaum Ntiaj Teb Tsov Rog 2 nyob rau hauv kev rau siab rau standardize European steel ntau lawm. EN sawv cev rau European Norm, txhais tau tias cov qhab nia no tau siv feem ntau thoob plaws hauv Tebchaws Europe.

UNS Qib

Lub Unified Numbering System yog ib qho kev tsim qauv siv hlau feem ntau siv thoob plaws hauv North America. Qhov sib txawv tseem ceeb ntawm UNS thiab cov tshuab Asmeskas zoo sib xws xws li AISI thiab SAE yog qhov Kev Sib Koom Tes Sib Koom Tes muaj cov npe dav dav ntawm cov hlau, thiab tsis txwv rau cov hlau.

18/8, 18/10 thiab 18/0 Qib

18/8, 18/10, thiab 18/0 yog cov npe nrov rau cov qib stainless hlau feem ntau pom muaj nyob rau hauv cov tais diav thiab khoom ua noj. Cov qhab nia no feem ntau tsis siv los xa mus rau cov fasteners thiab engineering Cheebtsam, tab sis lawv siv tsis tau hnov ​​​​txog. Cov npe no yog cov piv txwv yooj yim ntawm txhua qib kev muaj pes tsawg leeg, nrog rau txhua qib muaj 18% chromium, thiab 8%, 10%, lossis 0% (tus lej) ntawm nickel. Cov qib xws li 18/0 feem ntau tau txo cov ntsiab lus npib tsib xee kom txo cov nqi - txawm li cas los xij, kev txo cov npib tsib xee muaj qhov tsis zoo rau kev tiv thaiv corrosion.
