Iibholiti zeNtsimbi eStainless: Iibholiti zeHex kunye namaBanga oMathiriyeli

2026-08-05

1. Intshayelelo

Iibholiti zentsimbi estainless zidibanisa ukuxhathisa okungokwemvelo kunye namandla oomatshini, zibenza babaluleke kuwo wonke ulwakhiwo, elwandle, ekusetyenzweni kokutya, kunye namashishini ezonyango. Ngokungafaniyo ne-carbon steel fasteners ezifuna iingubo ezikhuselayo, insimbi engenasici ifumana ukuxhathisa kwayo kwi-corrosion kwi-self- healing chromium oxide layer. Esi sikhokelo sibandakanya eyona miba mibini ibaluleke kakhulu: uyilo lwe-hex bolt kunye nokukhethwa kwebakala lensimbi engenasici.

2. Iibholiti zeHex

Iibholiti zeHex zinentloko enamacala amathandathu evumela ukuhanjiswa kwetorque ngokufanelekileyo ngezitshixo eziqhelekileyo okanye iisokethi. Uyilo lubandakanya intloko ene-hexagonal, i-shank engafundwanga, inxalenye enemisonto, kunye nencam ye-chamfered. Iinzuzo eziphambili zibandakanya umthamo ophezulu we-torque, ukufikeleleka jikelele, ukusebenza kakuhle kokuvelisa, ukusebenziseka kwakhona, kunye nokuthotyelwa kwemigangatho yamazwe ngamazwe (ISO 4014, DIN 933, ASTM A325).

ITheyibhile 1. Iisayizi zeBholithi eziMgangatho zeHex (Intsimbi engatyiwayo)

Ubungakanani bobizo	Umsonto wePitch (TPI)	Ububanzi bentloko (mm)	Amandla Okuqina (MPa)
1/4 - 20	20	11.1	520
3/8 - 16	16	14.3	520
1/2 - 13	13	19.1	520
3/4 - 10	10	28.6	520

3. AmaBanga eStainless Steel

Izibophelelo zensimbi ezingenasici zihlelwa kwiintsapho ezine: i-austenitic (304, 316 - non-magnetic, ukumelana ne-corrosion ephezulu), i-ferritic (430 - magnetic, economical), i-martensitic (410 - i-hardenable, i-corrosion ephakathi), kunye ne-precipitation-hardening (17-4PH - amandla aphezulu). Ngaphantsi kwe-ISO 3506, amabakala asebenzisa ikhowudi enobumba-nombolo apho A = austenitic, C = martensitic, kwaye inani lichaza iklasi yamandla e-tensile (50/70/80).

Itheyibhile 2. AmaBanga eNsimbi eStainless aqhelekileyo kwiiBolts

IBanga	ISO Class	I-Tensile (MPa)	Ukuxhathisa ukonakala.	Iimpawu eziphambili	Usetyenziso oluqhelekileyo
304	A2-70	700	Kulungile	18% Cr, 8% Ni	Injongo ngokubanzi, ukutya
316	A4-70	700	Egqwesileyo	16% Cr, 10% Ni, 2% Mo	Ulwandle, ikhemikhali, unyango
410	C3-80	550	Phakathi	12% Cr	I-Cutlery, iivalve
17-4PH	A4-80	800	Kulungile	16% Cr, 4% Ni, 4% Cu	I-Aerospace, amandla aphezulu

Uluhlu 3. Amabanga acetyiswayo ngokwemeko-bume yeNkonzo

Okusingqongileyo	IBanga elicetyiswayo	Isizathu
Ngaphakathi / Yomile	304 (A2)	Yanele ngexabiso eliphantsi
Ngaphandle / Elunxwemeni	316 (A4)	UMo uyaxhathisa uhlaselo lwekloridi
Isityalo seMichiza	316L / 904L	Ukuxhatshazwa kwe-asidi ephezulu
IiMfuno zokomelela okuphezulu	17-4PH (A4-80)	Imvula-yaqina

Iibholiti zeNtsimbi ye-Stainless i-Hex Bolts kunye namaBanga oMathiriyeli

4. Iingqwalasela eziphambili

Galling: Amabanga e-Austenitic (304, 316) ajwayele ukubamba intambo ngexesha lokuqinisa. Sebenzisa iikhompawundi ezichasene nokubanjwa okanye ukudityaniswa komgangatho ongafaniyo (i-A2 bolt ene-A4 nut) ukunciphisa.

Ukunyusa: Ukunyangwa kwe-Acid (ASTM A967) isusa isinyithi yamahhala kwaye iphucula i-oxide layer, iphucula ukuxhathisa kwe-corrosion emva kokuvelisa.

Imagnethi: Amabanga e-Austenitic awanamagnetic xa efakwe kodwa anokuba yimagnethi emva kokusebenza okubandayo. Amabakala e-Ferritic kunye ne-martensitic angokwemvelo enemagnethi.

5. Isiphelo

Iibholiti zentsimbi yeheksi engenazintsimbi zidibanisa uyilo olusebenzayo lwejometri kunye nokuguquguquka kwesinyithi. Ukususela kwiBanga le-304 loqoqosho lokusetyenziswa ngokubanzi ukuya kumandla aphezulu we-17-4PH kwizicelo ezifunwayo, ukufanisa ibakala elichanekileyo kwindawo yenkonzo kuqinisekisa ukusebenza kakuhle kunye nokuphila ixesha elide.

Andinayo. Okulandelayo.
