Tutu Ṣiṣẹ Ọpa Irin D3 1.2080 SKD1 alapin bar

Irin irin D3 jẹ erogba giga-giga, chromium giga, irin irin-lile epo ti o jẹ ijuwe nipasẹ lile lile ti o ni ibatan ti o ga pupọ ati lọpọlọpọ, nla, chromium-ọlọrọ alloy carbides ni microstructure. Awọn carbides wọnyi pese resistance to dara lati wọ lati olubasọrọ sisun pẹlu awọn irin miiran ati awọn ohun elo abrasive.

D3 ṣe afihan iduroṣinṣin to dara julọ ni itọju ooru, didimu iwọn fẹrẹẹ bii gbigbo afẹfẹ, carbon-giga, awọn irin-giga-chromium kú bi D2.

ohun elo:

1.Fun iṣelọpọ ti awọn tutu tutu ati awọn punches ti o wa labẹ awọn ẹru ipa kekere, kekere si awọn iwọn iṣelọpọ alabọde, ati pe o nilo resistance resistance to gaju.

2. Tutu Ige abẹfẹlẹ fun gige lile ati tinrin irin

3. Fun awọn apa aso lu, awọn wiwọn, iyaworan okun waya ku, embossing ku, crepe farahan, iyaworan kú, tutu extrusion ku ati dabaru rola ku.

4. Dara fun iṣelọpọ nla, eka ati pipe awọn apẹrẹ ṣiṣu ti o nilo resistance giga
