Khoom Piav Qhia
AISI 420B thiab 420C stainless hlauyog cov qib siab carbon martensitic qib paub txog lawv cov hardness zoo heev, hnav tsis zoo, thiab mob corrosion tsis kam. Cov ntaub ntawv no zoo tagnrho rau kev tsim cov khoom siv dag ntxias tau siv hauv cov ntawv thov siab xws li cov khoom siv kho tshuab, cov cuab yeej kho tsheb, thiab cov cuab yeej kho kom haum.
420 Martensitic Stainless Hlau Yeeb Nkab
Cov Ntaw Ntaw Ntawm Aisi 420B \/ C Stainless Hlau Seamless Kav
Siab hardness thiab lub zog
AISI 420B \/ C Pipes Ua kom tiav siab dua tom qab kev kho cua sov (nce txog HRC 52-58), ua rau lawv ua kom tsis kam.
Zoo heev tasinability
Nyob rau hauv annealed mob, cov kav dej no muaj zoo machinability thiab qhov seem ruaj khov thaum lub sijhawm fabrication.
Moderate corrosion tsis kam
Nrog rau 12-14% chromium cov ntsiab lus, 420B \/ c stainless hlau muab tsim cov tshuaj lom neeg thiab cov me me los yog passivated.
Zoo saum npoo ua tiav
Seamless kav tuaj yeem muab rau hauv polished, pickled, lossis ci annealed cov xwm txheej kom tau raws li cov tsos mob thiab kev ua tau zoo.
Vim li cas thiaj xaiv GNEE
Cov khoom lag luam zoo: txhua pob ntawm cov kav dej yog nrog en 10204 3. 1 lub sij hawm ntsuas (1.5 lub sij hawm ua haujlwm siab rau 30 feeb
Kev xa tawm ceev ceev: 500 tons ntawm cov ntsiab lus tseem ceeb (xws li φ25.4 × 1. "yuav xa ncaj qha rau hauv 3-7 hnub tom qab tso ib qho kev txiav txim. Cov pob pob me me yog kev txhawb nqa (tsawg kawg nkaus xaj ntawm 100 meters).
