ST37 SS400 H Channel Steel

Cov khoom siv SS400 yog cov khoom sib txawv ntawm cov qauv hlau. Nws yog ib qho tseem ceeb nyob rau hauv ntau yam engineering thiab kev tsim kho tej yaam num vim nws superior zog-rau-qhov hnyav piv thiab siab corrosion kuj.Known rau nws zoo weldability thiab machinability, SS400 cov ntaub ntawv bears qhov txawv qhov zoo. uas teem nws sib nrug los ntawm nws cov counterpart, Mild Steel.ST 37 steel yog ib yam uas tsis muaj carbon steel nrog carbon cov ntsiab lus ntawm tsawg tshaj li 0.17%, Silicon tsawg dua 0.35, Manganese ntau tshaj 0.35, P thiab S txhua. siab tshaj 0.0. 4. DIN 2391 ST37 Yeeb Nkab kuj tseem siv dav hauv kev siv niaj hnub thiab kev siv cov qauv uas muaj zog siab tsis tseem ceeb.

Khoom Description

Cov tshuaj muaj pes tsawg leeg ntawm St37 steel plays lub luag haujlwm tseem ceeb hauv kev txiav txim siab nws lub cev thiab cov khoom siv kho tshuab, nrog rau cov khoom tseem ceeb yog hlau, carbon, thiab manganese. Cov hlau versatility thiab lub zog yog ncaj qha cuam tshuam los ntawm cov khoom no, uas txhais nws cov durability, corrosive kuj, thiab thermal conductivity.

Cov txheej txheem hardening, uas suav nrog cua sov cov hlau saum nws qhov ntsuas kub tseem ceeb thiab tom qab ntawd maj mam txias nws, ntxiv dag zog rau cov khoom no. Cov txheej txheem no hloov cov hlau lub microstructure, nce nws hardness thiab lub zog.

Ntxiv mus, cov txheej txheem carburizing kuj tuaj yeem siv los txhim kho St37 steel cov khoom siv kho tshuab. Qhov no thermochemical kev kho mob enriches cov hlau nto txheej nrog carbon, yog li pab txhawb nws hnav tsis kam. Kev saib xyuas yuav tsum tau ua, txawm li cas los xij, kom ntseeg tau tias cov ntsiab lus carbon nyob rau hauv txheej txheej tsis tshaj 0.9%, vim qhov no tuaj yeem ua rau tsim cov cementite thiab ua rau cov hlau tsis muaj zog.

Lub cev lub cev ntawm ob qho tib si SS400 thiab cov hlau me me ua lub luag haujlwm tseem ceeb hauv kev txiav txim siab lawv qhov tsim nyog rau kev siv sib txawv.

SS400 muaj qhov ceev ntawm 7.85g / cm3, uas cuam tshuam nws qhov hnyav thiab lub zog. Nws qhov hardness yog ntsuas nyob rau hauv Brinell nplai, qhia kuj tsis tshua muaj hardness tab sis tsim nyog toughness, muab zoo kuj rau cracking.

Lub thermal conductivity ntawm SS400 yog kwv yees li 25.93 W / mK, tso cai rau cov cua sov kom faib cov khoom sib npaug, ua rau nws tsim nyog rau cov ntawv thov uas xav tau qhov kub thiab txias. Cov hluav taws xob conductivity, thaum tsis yog nws cov yam ntxwv tseem ceeb, yog txaus rau feem ntau cov ntawv siv. Nws cov khoom sib nqus yog piv rau cov hlau me me, ua rau nws tsim nyog rau cov ntawv thov uas cov hlau nplaum tseem ceeb.

Ntawm qhov tod tes, cov hlau me me muaj qhov zoo sib xws rau SS400, ua rau nws lub zog thiab qhov hnyav. Nws nthuav tawm lub hardness siab dua tab sis qis dua toughness dua li SS400, ua rau nws tsis tshua muaj resistant rau tawg tab sis ntev dua.
