ASTM A194

Mafotokozedwe a ASTM A194 amaphimba mtedza wa kaboni, aloyi ndi zitsulo zosapanga dzimbiri zomwe zimagwiritsidwa ntchito pazovuta kwambiri komanso / kapena kutentha kwambiri. Pokhapokha ngati tafotokozera, American National Standard Heavy Hex Series (ANSI B 18.2.2) idzagwiritsidwa ntchito. Mtedza mpaka ndi kuphatikiza 1 inchi kukula mwadzina adzakhala UNC Series Class 2B wokwanira. Mtedza wopitilira inchi imodzi kukula kwake mwadzina udzakhala wokwanira wa UNC Series Class 2B kapena 8 UN Series Class 2B wokwanira. Mtedza wamphamvu kwambiri wa ASTM A194 giredi 2H ndiwofala pamsika ndipo nthawi zambiri amasinthidwa ndi mtedza wa ASTM A563 grade DH chifukwa cha kupezeka kochepa kwa mtedza wa DH pama diameter ena ndi kumaliza.

ZOYENERA: 1. Zizindikiro zomwe zawonetsedwa pamagiredi onse a mtedza wa A194 ndi za mtedza wozizira komanso wonyezimira. Mtedza ukapangidwa kuchokera ku bar stock, mtedzawo uyenera kulembedwanso chilembo 'B'. Zilembo H ndi M zimasonyeza mtedza wotenthedwa. 2. Katundu wowonetsedwa ndi wa mtedza wa hex wobiriwira komanso ulusi wa 8-pitch heavy. 3. Manambala olimba ndi Brinell Hardness. 4. Mtedza womwe umathandizidwa ndi carbide solution umafunikira kalata yowonjezera A - 8A kapena 8MA. 5. Mtedza wonse uzikhala ndi chizindikiritso cha wopanga. Mtedza uyenera kulembedwa pankhope imodzi kusonyeza kalasi ndi ndondomeko ya wopanga.
