HRB400 Steel Qws

Threaded steel tuav, feem ntau hu ua kub-dov ribbed steel tuav, yog me me-section steels uas yog siv nyob rau hauv lub cev pob txha ntawm cov pob zeb ua vaj tse. Nws cov xov tsim txhim kho kev sib raug zoo ntawm cov hlau tuav thiab pob zeb, thiab txhim kho tensile thiab shear tsis kam ntawm cov qauv. Threaded steel tuav feem ntau yog ua los ntawm cov hlau tsis muaj hlau lossis cov hlau tsis tshua muaj hlau, thiab cov kev qhia tshwj xeeb suav nrog HRB335, HRB400 thiab HRB500.

 

Qhov zoo

High yield zog
HRB400 Steel Qws txais cov txheej txheem kub dov, los ntawm cov cua sov, cov yas deformation thiab txias txheej txheem, cov txheej txheem sab hauv ntawm cov hlau yog ua kom zoo dua qub, thiab lub zog tawm los yog txhim kho; cov ntsiab lus silicon hauv HRB400 yog tswj hwm ntawm 0.2-0.8%, uas pab txhim kho lub zog tawm los thiab ruaj khov ntawm cov hlau. Nyob rau tib lub sijhawm, cov ntsiab lus phosphorus thiab sulfur yog tswj nyob rau hauv qhov siab tshaj plaws ntawm 0.045%, uas txo qhov kev puas tsuaj ntawm impurities rau cov qauv khoom thiab txhim kho lub zog ntawm cov khoom; lub zog tawm los ntawm HRB400 steel bar nce mus txog 400 MPa, uas yog siab dua HRB335 thiab tuaj yeem tswj kev ruaj ntseg hauv cov khoom hnyav dua.

 

Lub zog tensile zoo heev
Qhov muaj pes tsawg leeg ntawm HRB400 Steel Qws yog optimized, muaj cov pa roj carbon ntau (0.17-0.25%) thiab manganese (1.2-1.6%), uas ua rau kom cov lub zog thiab hardness ntawm steel. Manganese tsis tsuas yog txhim kho lub zog tensile ntawm cov hlau, tab sis kuj txhim kho toughness thiab hnav tsis kam; lub zog tensile ntawm HRB400 steel bar yog 540 MPa, ua kom muaj kev tiv thaiv zoo rau tensile kev nyuaj siab hauv cov qauv thiab txhim kho kev nyab xeeb; txij li thaum lub elongation ntawm HRB400 steel bar yog 16%, nws tuaj yeem deform me ntsis txawm tias nyob rau hauv kev ntxhov siab siab kom tsis txhob tawg tawg.

 

Composition optimization
HRB400 Steel Qws muaj 0.17-0.25% carbon, 1.2-1.6% manganese thiab 0.2-0. 8% silicon, nrog tus nqi tsim nyog, muab lub zog zoo thiab tawv; phosphorus thiab sulfur cov ntsiab lus hauv HRB400 yog tswj tsis pub dhau 0.045%. Cov ntsiab lus qis ntawm cov impurities no txo ​​cov tiam ntawm nkig theem thiab txhim kho cov ductility thiab cuam tshuam tsis kam ntawm cov khoom.

 

Corrosion kuj
Cov ntsiab lus phosphorus thiab sulfur ntawm HRB400 Steel Rods yog tswj nyob rau hauv 0.045%. Phosphorus thiab sulfur yog cov teeb meem impurities. Cov ntsiab lus siab dua yuav ua rau kom brittleness thiab corrosion ntawm steel. Cov hlau tuav muaj 0.2-0.8% silicon, uas ua lub luag haujlwm antioxidant hauv cov hlau thiab tuaj yeem tsim cov yeeb yaj kiab oxide tiv thaiv kom qeeb qhov tshwm sim ntawm corrosion. Cov ntsiab lus manganese ntawm 1.2-1.6% nce lub zog thiab hardness ntawm hlau. Cov txheej txheem kub dov tsis tsuas yog txhim kho cov khoom siv kho tshuab ntawm cov khoom siv, tab sis kuj txhim kho qhov ntom ntawm cov hlau nto.

 

Kev siv dav dav
HRB400 Steel Rods tuaj yeem siv rau hauv cov pob zeb ua vaj tse, xws li cov hauv paus, kab teeb, kab thiab hauv pem teb slabs, los txhim kho lub zog tensile thiab bearing peev xwm ntawm pob zeb; nyob rau hauv cov chaw txuag dej xws li dams thiab levees, lawv tuaj yeem siv los txhawb cov pob zeb ua vaj tse los tiv thaiv dej ntws; lawv kuj tuaj yeem siv los txhawb cov tsev lag luam thiab cov cuab yeej siv los txhawb kev teeb tsa thiab kev ua haujlwm ntawm cov cuab yeej siv tshuab loj.
