FAQ
Kodi chida cha DIN 1.2581 H21 ndi chiyani?
DIN 1.2581 H21 ndi chida chogwirira ntchito chotentha chopangidwa ndi tungsten. Chimagwiritsidwa ntchito pazida zomwe zimagwira ntchito kutentha kwambiri, kutopa komanso kutentha kwambiri, monga ma hot forging dies, hot punch ndi extrusion tooling.
Kodi H21 ndi yofanana ndi SKD5?
H21 ndi SKD5 nthawi zambiri amagwiritsidwa ntchito pofotokozera za mtundu womwewo wa chitsulo chotentha cha tungsten. Kufanana komaliza kuyenera kutsimikiziridwa ndi muyezo wofunikira, kapangidwe ka mankhwala, chithandizo cha kutentha ndi zofunikira zowunikira.
Kodi muyezo wotani umagwira ntchito pa bala lachitsulo la zida za H21?
ASTM A681 nthawi zambiri imagwiritsidwa ntchito pa chitsulo cha AISI H21, pomwe DIN EN ISO 4957 ingagwiritsidwe ntchito pa DIN 1.2581 / X30WCrV9-3. Lamulo logulira liyenera kufotokoza muyezo wofunikira ndi kusinthidwa.
Kodi ubwino waukulu wa H21 ndi wotani poyerekeza ndi H13?
H21 ili ndi tungsten yapamwamba kwambiri, yomwe imapangitsa kuti kuuma kofiira kukhale kolimba komanso kukana kufewa m'malo ena otentha kwambiri. H13 imagwiritsidwa ntchito kwambiri ndipo imapereka kulimba kosiyana, kukana kutopa ndi kutentha komanso kupezeka kwake.
Kodi bala la H21 lingaperekedwe kuphwanyidwa kapena kuchotsedwa?
Inde. Malo akuda, odulidwa, ozunguliridwa ndi nthaka akhoza kukambidwa malinga ndi kukula, kulolerana ndi zofunikira zomaliza zogwirira ntchito. Mipiringidzo ya pansi ndi yoyenera pamene pakufunika kuwongolera kwambiri kukula kwa mainchesi kapena kukonza bwino mawonekedwe a pamwamba.
Kodi kuyezetsa kwa ultrasound kulipo pa mipiringidzo ya H21?
UT ikhoza kukonzedwa kuti ipange ma diameter oyenera a bar ndi forged bar ngati yatchulidwa. Dongosolo liyenera kufotokoza njira yoyesera, mulingo wovomerezeka ndi zofunikira pakupereka malipoti.
Kodi MTC ndi EN 10204 3.1 zingaperekedwe?
SAKY STEEL ikhoza kupereka zikalata za MTC ndi EN 10204 3.1 malinga ndi dongosolo logulira. Malipoti olimba, amitundu, a PMI kapena a UT angakonzedwenso ngati atchulidwa.
