EN 1.4373 yog dab tsi?
EN 1.4373 yog ib qho austenitic stainless hlau, tseem hu ua AISI 202, uas yog ib qho kev lag luam rau cov tsoos stainless hlau zoo li 304. Nws yog siv rau hauv cov ntawv thov kom muaj zog, xws li cov khoom siv nkoj, cov khoom siv tsheb, cov khoom siv kho mob, thiab cov khoom siv rau kev lag luam tshuaj thiab zaub mov.
Dab tsi yog qhov sib npaug ntawm 1.4373 stainless hlau?
Cov khoom sib npaug rau stainless hlau 1.4373 yog AISI 202 (los yog UNS S20200) thiab nws cov npe suav 1Cr18Mn8Ni5N. Nws yog austenitic chromium-nickel-manganese stainless hlau thiab ib qho kev xaiv pheej yig dua li cov hlau tsis huv xws li 304.
1.4372 vs.1.4373 Stainless hlau
Qhov sib txawv tseem ceeb yog tias stainless hlau 1.4372 muaj cov ntsiab lus qis manganese thiab npib tsib xee, thaum stainless hlau 1.4373 muaj cov ntsiab lus ntau dua manganese. Ob leeg yog austenitic stainless hlau, tab sis lawv qhov sib txawv sib txawv ua rau muaj kev hloov pauv me ntsis hauv cov khoom siv kho tshuab thiab qhov sib txawv ntawm lawv cov npe tshuaj lom neeg: 1.4372 tseem hu ua X12CrMnNiN17-7-5 thiab 1.4373 yog X12CrMnNiN18-9-5.

1.4372 vs . 1.4373 Stainless Steel: Machining Properties
1.4373 (AISI 303) muaj qhov zoo ntawm kev ua haujlwm zoo dua li 1.4372 (AISI 201) vim nws cov ntsiab lus sulfur ntau dua; sulfur yog ntxiv los txhim kho machinability . 1.4373 tau yooj yim ua cov ntaub ntawv zoo, xoob chips, yog li nws tau suav hais tias yog ib qho zoo tshaj plaws machinable stainless hlau, thaum 1.4372 muaj cov tshuab tsis zoo thiab nyuaj rau tshuab.
1.4372 vs . 1.4373 Stainless Steel: Corrosion Resistance
1.4373 (tseem hu ua 201) feem ntau muaj me ntsis corrosion kuj zoo dua li 1.4372 (tseem hu ua 201) vim hais tias cov "sulfur-} nplua nuj" muaj pes tsawg leeg ntawm 1.4373 txhim kho nws cov corrosion kuj. Ob qib ntawm stainless hlau muaj zoo atmospheric thiab acid tsis kam, nrog 1.4373 tus corrosion kuj yog ntxiv txhim khu kev qha los ntawm nws cov ntsiab lus sulfur qis.
1.4372 thiab 1.4373 Stainless Hlau: Weldability
