Product Overview
Alloy steel tiaj tiaj bar yog tsim los ntawm kub dov, forging, los yog txias kos duab, siv high -kev ua tau zoo alloy qib tsim los rau siab - kev nyuaj siab mechanical Cheebtsam. Cov ntaub ntawv no muab superior tensile zog, hardenability, thiab hnav tsis kam piv rau cov qauv carbon steel.
Muab nyob rau hauv annealed los yog quenched & Tempered (Q&T) tej yam kev mob, peb ca bars ua raw khoom rau cov yam ntxwv qhov chaw, hnyav machinery Cheebtsam, thiab tooling. Txhua pawg tsim khoom tau txais kev txhawb nqa los ntawm cov ntaub ntawv pov thawj zeb kuaj tau ua raws li ASTM, EN, lossis JIS cov qauv.

Customization & Ua
Siab - muaj peev xwm tsis siv neeg band saws muab cov thaiv thaiv lossis qhov ntev ntev (siab ntev hauv +/-1.0 mm), txo qis hauv seem ntawm koj qhov chaw.
Cov cua sov tswj cua sov ua rau kev ua kom zoo, ua kom zoo, thiab dhau los ntawm - hardening rau qhov tshwj xeeb hardness ranges (xws li, 28-32 HRC lossis cov phiaj xwm kev cai khoom siv).
Rough tig, milling, thiab deg sib tsoo tshem tawm cov txheej txheem decarburized thiab xa npaj txhij - mus rau - cov khoom lag luam nrog cov khoom zoo tshaj plaws.
Kev Tswj Xyuas Zoo & Kev Tshuaj Xyuas
Kev ua raws li kev tsim khoom raug txheeb xyuas ntawm cov chaw kuaj xyuas cov khoom tseem ceeb uas siv cov cuab yeej ntsuas ntsuas ntsuas:

FAQ
Q: Dab tsi yog qhov tsawg kawg nkaus txiav txim kom muaj nuj nqis (MOQ) rau cov tsis yog - cov qauv alloy qib lossis kev cai qhov ntev?
A: MOQ feem ntau pib ntawm 3 metric tons ib qhov loj / qib rau kub - dov los yog forged ntau lawm khiav. Cov khoom me me tuaj yeem muaj yog tias sib tw nrog cov sijhawm tsim khoom lag luam lossis cov khoom lag luam uas twb muaj lawm.
Q: Koj puas tuaj yeem muab Ultrasonic Testing (UT) cov lus ceeb toom rau tuab -section tiaj tus tuav?
A: Yog. Kev xeem UT rau ASTM A388 lossis EN 10308 yog muaj thaum thov. Cov ntaub ntawv ntsuam xyuas suav nrog EN 10204 3.1 Mill Test Certificate ua ntej xa khoom.
Q: Dab tsi yog qhov txawv ntawm kev xa khoom ntawm annealed thiab Q&T tuav?
A: Annealed tuav muaj qis hardness qib optimized rau machinability thiab txias forming. Quenched & Tempered (Q&T) cov tuav tau dhau los ua kev kho cua sov kom ua tiav lub zog tensile siab dua thiab cov qib hardness predetermined, npaj rau kev koom ua ke ncaj qha.
Q: Koj yuav ua li cas tiv thaiv xeb ntawm cov kab tiaj tus thaum lub caij hla dej hiav txwv ntev?
A: Bars yog coated nrog industrial-qeb xeb- tiv thaiv roj thiab bundled ruaj ntseg. Rau kev xa khoom mus los ntawm qhov siab - cov av noo nyob rau hauv marine ib puag ncig, VCI zaj duab xis wrapping thiab desiccant tso rau hauv daim ntawv cog lus.
Q: Koj tus qauv thickness thiab dav tolerances yog dab tsi?
A: Kev ua siab ntev ua raws li ASTM A29 lossis EN 10058 tus qauv nyob ntawm seb lub bar yog kub- dov, txias- kos, lossis precision- hauv av. Cov kev txwv tshwj xeeb tuaj yeem pom zoo ua ntej kev txiav txim pom zoo.
Q: Cov nqe lus them nqi dab tsi koj lees txais rau cov nyiaj B2B tshiab?
A: Cov ntsiab lus txheem yog T / T (30% tso nyiaj, sib npaug tiv thaiv daim ntawv Them Nqi thiab MTC) los yog irrevocable Letter of Credit (L/C) thaum pom rau cov khoom tsim nyog.
