A chak zawk chuan fastener tan chuan a tha zawk tihna a ni lo!

The Expression A chak zawk chuan a tha zawk angin a lang a, chu chu nunah thil engemaw zat a ni a, mahse fastener-te hi chutiang thil zinga mi an ni hauh lo. Dik tak chuan mi tam tak chuan an chakna sang zawk chung pawha strength fastener sang tak tak pawh an hlawhchham emaw, an chhe emaw theihna dinhmunah an inhmu tawh mai thei. Hei hian fastener-ah hian chakna a pawimawh em tih leh fastener nena inzawmnaah hian chakna pawn lam ngaihtuah tur dang eng nge awm tih zawhna zawng zawng a rawn keng tel a ni.

 

Fastener chakna dik tak thlang tur leh fastener dik lo hman avanga i project tihchhiat loh nan fastener’s value te ngaihtuah a ngai ang.Yield chakna .lehTensile chakna ..

 

Fastener thlan hunah yield strength emaw tensile strength emaw a pawimawh zawk em?

A tlangpuiin fastener thar lei hmain tensile strength ngaihtuah hmasa phawt tur a ni fo. Hei hi a chhan chu fastener-a tensile strength chu fastener-in a vawn tlat theihna tura a mamawh tur load sang ber aiin a sang zawk daih tur a ni. Tensile strength chu maximum load aia hniam a nih chuan fastener chu a chunga load dah chu a handle theih loh avangin a deformed theihna tur hmunah i dah theihna a sang zawk.

 

I project atana type dik tak, tensile strength dik tak nei fastener zawng tur chuan Aya Fasteners te chu i biak theih reng a, i project-a fastener hman tur atana tensile strength dik tak chu eng nge ni ang tih expert opinion i hmu thei ang. Hei hi i budget chhunga i thawh theihna tura thil pawimawh tak a ni thei a, a theih ang anga hna thawh tur thawk thei tur fastener i nei ang.

 

Fastener thlan hunah hian chakna chu thil pawimawh ber a ni em?

Fastener thlan chungchangah hian chakna lam kan ngaihtuah nasa hle laiin, a tak takah chuan fastener hman tur leh application hian fastener hman tur chi hrang hrangah nghawng a nei dawn tih hi a ni. Fastener hmangtu tam tak chuan ‘a chak zawk chuan a chak zawk’ tih ideology-ah an ngaihtuahna an dah laiin i fastener-te chu structurally fail theih chhan dang awm thei zawng zawng, chakna nena inzawmna nei lo an awm theih chhan dang zawng zawng chu an hre lo ang.

 

Hydrogen hian fastener-ah nghawng tha lo tak a nei thei a ni. Dik tak chuan, i hman fastener-a brittle-type failures a thlen tlangpui dawn a, chu chu hydrogen-in steel chi hrang hranga nghawng a neih theih vang a ni.
Hydrogen-in steel-a nghawng a neih dan sawina chu kum 1875-a Royal Society-in WH Johnson-a’n a tihchhuah paper-ah a ni thei. Chuta ṭang chuan hydrogen-in steel a nghawng dan zirchianna tam tak a awm leh ta a ni.
A bik takin, hydrogen hian cracking a thlen fo thin a, chu chu hydrogen embrittlement tia hriat a ni bawk. Hei hi steel-ah chauh ni lovin, titanium ang chi metal dangah pawh a awm fo bawk. Atomic hydrogen hian material-ah hian a lut tak tak thei a, a nih loh leh fastener i hman chhung zawng emaw, fastener service life chhung zawng emaw a lut thei bawk. A hnuhnung zawkah chuan fastener-a hmuh theih fo emaw, boruak chhunga hydrogen tam tak awm thin emaw avanga lo awm a ni tlangpui.

 

Hydrogen embrittlement tih hi eng nge ni?

Hydrogen embrittlement hi hydrogen nena an inzawmna avanga metal te brittle an nih chuan a thleng tlangpui thin. Microstructure i hmanna fastener-in hydrogen a lakluh zat a zirin embrittlement level hrang hrang a tawk ang. Embrittlement hian a tawpah chuan cracking a thlen thei bawk a, chu chuan i siam tawh structure zawng zawng chu a tichhe vek thei ang.

 

Fastener chu hman hmain hydrogen nen an inzawm tawh em tih i hre thei ang em?

 

 

 

 

 

 

Hydrogen vangin brittle fracture avanga fastener a nghawng theih nan eng thil nge mamawh?

Fastener-in brittle fracture a tawn theih nan hian thil chi hrang hrang pathum a awm a ngai dawn a ni. Hengte hi a hnuaia mi te hi an ni:

 

Engtin nge hydrogen hi steel siamnaah hian siam chhuah a nih?
Thil siam chhuah lai hian hydrogen hi steel-ah an luhtir theih dan kawng hrang hrang a awm a. A tam zawk chu electroplating process chhung hian hydrogen hi hman tan a ni a, mahse, a chhan chu pickling, gas carburizing, heat treatment, leh thread rolling atanga process dang bakah a luh tir thin bawk.
Mahse, chuti chung pawh chuan non-electroplated fastener-te chu hydrogen embrittlement-a an fail chuan a awm lo tlangpui. Hei vang hian hydrogen embrittlement chance tihtlem nan electroplating neih laiin extra action lak a ni tlangpui. Heng process te hi heat treatment operation leh plating a rang thei ang bera hman te a ni. Dik tak chuan ISO 4042-in a sawi dan chuan, chu process chu hydrogen embrittlement chance tihtlem nan darkar li chhunga neih a ngai a ni.

 

Chumi chhanna chu i project i lak dan azirin a danglam mai thei. A tam zawk tan chuan property class 10.9 fastener te hi fastener chak tak leh brittle lo thei lo ve ve a nih chuan inremna tha ber an ni tlangpui.

 

Tawpna
Tensile strength hi project tin ah a pawimawh hle thei a, fastener chak tawk lo te chu a tlakbuak mai mai emaw, thil chi hrang hrang awm te chu an inzawm khawm thei lo emaw a ni thei. Mahse, chakna chauh hi ngaihtuah tur a ni lo. A chakna belhchhah nen chuan fastener i thlan mek nena inzawm risk a awm bawk. Fastener chak zawk hi hydrogen-ah an luhtir tam zawk a, hei hian hydrogen embrittlement a thlen thei a ni. Hydrogen embrittlement tih awmzia chu i fastener-a pressure a awm veleh fastener chu a chhe thei a, a chhe thei bawk. Hei hi thil siamna kawngah harsatna lian tak a ni a, chu chuan i project pumpui tihbuai a thlen thei a ni.
