Peb cov Carbon Steel Hex Nuts yog ua raws li ASTM A194 standard, siv low-carbon steel nrog 0.25-0.3% carbon thiab 0.6-1.05% manganese. Qhov sib tov no muab lawv qhov sib zog ntawm lub zog thiab ductility - tensile zog nyob ntawm 550-700 MPa, yog li lawv tuav nyob rau hauv siab yam tsis muaj cracking.

Lawv tsim los ua khob zoo nrog carbon steel bolts, nrog UNC threads (ASME B1.1) uas haum smoothly tab sis lock securely. Peb sim lawv los ntawm tightening thiab loosening 50 lub sij hawm, thiab lawv tsis strip li yog - zoo nyob rau kev tsim kho, machinery, los yog ib qho general industrial siv uas corrosion tsis yog ib qho kev hem loj. Rau wholesalers, lawv yog ib qho nqi-effective staple uas npog feem ntau yooj yim fastening xav tau.

Peb muab ob yam tiav: plain (mill finish) rau sab hauv siv thiab dub oxide coated (per ASTM D769) rau ntxiv xeb tiv thaiv thaum khaws cia. Cov dub oxide txheej yog nyias tab sis tawv, dhau 48-teev humidity tests (ASTM D1748) nrog tsis muaj xeb liab.

Peb cov threading yog precise - Class 2B fit (ASME B1.1) txhais hais tias tau lawv screwed rau yooj yim tab sis yuav tsis loosen ntawm lawv tus kheej. Peb siv cold forging los tsim cov hex hau, uas khaws cov hlau muaj zog thiab tsis muaj qhov zoo. tag nrho lub txiv ntseej tau mus/no-go gauge check los Spy tias threads phim standard bolts, thiab peb yam lawv nyob rau hauv yas bins nrog dividers los tiv thaiv xov puas thaum hnub.

Raws li ib tug Suav manufacturers nrog 14 xyoo supplying EU thiab US hardware markets, peb khiav 10 txiv ntseej-forming machines thiab 6 threading kab, tsim tawm 6,000 tons txhua xyoo. Peb cov raw steel los ntawm ISO 9001-certified mills, thiab txhua txhua batch undergoes hardness test (Rockwell B 70-85, ASTM E18) kom ntseeg tau tau zoo.

Peb khaws 900-1200 tons hauv tsev khaws khoom ntawm peb lub Shanghai warehouse, npog qhov ntau thiab tsawg los ntawm ¼" txog 2" thiab thicknesses 5mm txog 30mm. Cov khoom muag hloov tshiab txhua hnub ntawm peb lub vev xaib, thiab FOB Shanghai cov khoom xa tuaj hauv Tshuag rau 48 teev - zoo kawg rau thaum koj cov neeg siv khoom xav tau ceev restocks.

Orders tshaj 100 tons tau 5.5% luv nqi, ntxiv rau dawb dub oxide txheej.

Peb qhov kev lees paub: Yog hais tias ib qho Carbon Steel Hex txiv ntseej strips thaum lub sijhawm nruab ib txwm tsis ua tau raws li ASME B18.2.2 qhov ntev, peb tuaj yeem xaiv lawv hauv 4 hnub thiab lawv tag nrho cov nqi thauj khoom. Peb kuj kaw cov nqi rau 30 hnub ntawm kev lees paub txiav txim, yog li koj tsis tas yuav txog tam sim no tus nqi spikes noj rau hauv koj cov margins.

Carbon steel (varies los ntawm qib, nrog rau:

6-sided hexagonal head (standardized rau wrench compatibility); head width across flats (WAF) thiab thickness proportional rau thread size (xws li, 1/4" nut muaj ~7/16" WAF hauv imperial standards).

Mechanical Properties

Mechanical Properties

Thread Standards

Imperial: Unified National Coarse (UNC) lossis Fine (UNF) per ASME B1.1.

Tsheb: Kev sib txuas cov khoom hauv chassis, kev ncua, lossis cav bays.

Piping: Koom nrog flanges, valves, thiab cov tshuab siab qis mus rau nruab nrab.

Lub hom phiaj dav dav: Txhua yam daim ntawv thov uas xav tau kev ruaj ntseg, rov siv tau cov xov txuas.

Ntsiab nta

Strength Matching: Tsim los ua khob nrog carbon steel bolts (nut strength feem ntau qis dua me kuv dua bolt los tiv thaiv thaiv tsis ua haujlwm).

Versatility: Standard hex design haum universal wrenches/sockets.

Nqi-zoo: Carbon steel muab zoo zog ntawm tus nqi qis dua alloy steel ceev.

Reusability: Tau muab tso rau thiab rov teeb tsa hauv cov pob qij txha tsis tas li.
