304L ndi mtundu wa 304 wopanda mpweya wambiri. Imagwiritsidwa ntchito mu zigawo zolemera kuti zigwirizane bwino ndi kusongoka.
304H, mtundu wa carbon wambiri, uliponso kuti ugwiritsidwe ntchito kutentha kwambiri.

Jiangsu Hangdong Metal Products Co., Ltd. ndi kampani yothandizidwa ndi Jiangsu Hangdong Iron & Steel Group Co., LTD. Ndi kampani yofufuza, kupanga, kugulitsa, ndi kupereka chithandizo mu imodzi mwa makampani opanga zinthu zachitsulo. Pali mizere 10 yopangira zinthu. Likulu lake lili mumzinda wa Wuxi, m'chigawo cha Jiangsu mogwirizana ndi lingaliro la chitukuko la "ubwino umagonjetsa dziko lapansi, kukwaniritsa ntchito mtsogolo". Tadzipereka kulamulira bwino khalidwe ndi kupereka chithandizo chabwino. Patatha zaka zoposa khumi tikumanga ndi kupanga zinthu, takhala kampani yophatikizana yopanga zinthu zachitsulo.
