Q355B H- ntu steel
Piv nrog rau qib dhau los, Q355B H Beams feature optimized mechanical zog, nruj zog tshuaj muaj pes tsawg leeg tswj, thiab txhim kho weldability, ua rau lawv zoo tagnrho rau niaj hnub kev tsim kho, txuas hniav, machinery, thiab loj -scale industrial lug uas xav tau siab - steel kev ua tau zoo.
S355JR Structural Steel Beams poob raws li European thiab Askiv tus qauv BS EN10025-2, dav siv hauv cov nroj tsuag, txuas hniav, chaw nres nkoj, thiab cov khoom siv tshuab loj.
Q355B H- ntu steel
Kev sib piv cov ntsiab lus ntawm cov tshuaj lom neeg muaj pes tsawg leeg thiab cov khoom siv tshuab qhia tau hais tias Q355B H-section steel thiab S355JR H Beams yog qhov sib npaug ntawm cov khoom muaj zog, lub zog tensile, thiab kev cuam tshuam toughness, tso cai rau cov engineers los hloov lawv hauv kev tsim, kev tsim kho, thiab thauj khoom -cov ntaub ntawv bearing.
Qhov sib npaug ntawm Q355B H Beams thiab S355JR Structural Steel Beams muaj kev yooj yim hauv kev xaiv cov khoom siv rau ob qho tib si hauv tsev thiab thoob ntiaj teb, ua kom muaj kev ua raws li cov qauv sib txawv hauv tebchaws.
Cov kws tsim qauv tuaj yeem xaiv Q355B lossis S355JR H Beams raws li qhov yuav tsum tau ua ntawm qhov project, lav cov qauv kev nyab xeeb, yooj yim ntawm kev tsim kho, cov khoom siv zoo ib yam, thiab cov nqi siv tau.

S355JR steel kuj sib npaug rau cov txheej txheem thoob ntiaj teb xws li ASTM A572 Qib 50, DIN 17100 St50-2, thiab JIS G3101 SS540.
Peb S355JR H Beams yog tsim los nrog nruj me ntsis kam rau ua kom paub meej cov qauv kev ua tau zoo. Qhov siab kam rau ua yog ± 2 hli, flange dav kam rau ua yog ± 2 hli, thiab lub web thickness kam rau ua yog ± 1 hli.
Ib yam li ntawd, peb Q355B H-section steel ua tau raws li cov qauv siab, muab qhov siab siab ± 2 hli, flange dav ± 3 hli, thiab lub web thickness ± 1 hli, ua rau nws zoo tagnrho rau cov haujlwm uas qhov tseeb thiab haum yog qhov tseem ceeb.
Los ntawm kev muab cov kab hlau nrog me me, peb pab cov engineers ua tiav kev sib dhos zoo dua qub, txhim kho cov qauv kev ruaj ntseg, thiab kev sib koom ua ke yooj yim dua nrog lwm cov khoom.
Rau txhua qhov ntau thiab tsawg ntawm S355JR thiab Q355B H Beams, peb lub siab ntev tswj xyuas kom ntseeg tau kev ua tau zoo, txo cov khoom pov tseg, thiab kev tsim kho sai dua.
Raws li S355JR thiab Q355B H Beams chaw tsim tshuaj paus, peb xa tag nrho cov qauv ntau thiab tsawg nrog kev ua siab ntev, pab koj ua kom zoo dua cov ntaub ntawv, txo cov khib nyiab, thiab ua kom muaj kev tsim kho.

Puas yog S355 sib npaug rau A36?
S355JR thiab A36 tsis sib npaug ncaj qha, raws li S355JR muaj lub zog ntau dua (yield 355 MPa vs. A36's 250 MPa) thiab lav qhov cuam tshuam toughness, ua kom ze rau ASTM A572 Qib 50 dua A36. A36 feem ntau sib npaug rau S235JR (yield 235 MPa), qis dua EN qib.
Dab tsi yog Asmeskas sib npaug ntawm S355 steel?
ASTM tau txheeb xyuas A572-50 raws li kev hloov pauv tau rau S355. Ob qib muaj cov tshuaj lom neeg zoo sib xws thiab muaj siab -lub zog, cov hlau tsis tshua muaj hlau.
S355 puas tuaj yeem hardened?
S355 tsis yog qhov zoo tshaj plaws rau kev ua kom tawv tawv, txawm hais tias nws tuaj yeem raug rau cov txheej txheem kev kho cua sov tsawg xws li cov ntaub ntawv hardening.
Dab tsi yog qhov txawv ntawm ASTM A572 thiab S355?
Daim ntaub ntawv: ASTM A572 Qib 50 feem ntau yog siv rau hauv cov ntawv siv hnyav dua uas xav tau lub zog ntau dua, thaum S355JR muaj ntau yam thiab siv dav hauv ntau yam kev siv hauv cov teb chaws Europe.
