kuita zvinodiwa
(1) Simba repamusoro: kazhinji, goho rayo simba riri pamusoro pe300MPa.
(2) Kuomarara kwepamusoro: kurebesa kunodiwa i15% ~ 20%, uye kuomarara kwepamhepo tembiricha yakakura kupfuura 600kJ/m~800kJ/m.Kune mahombe akaiswa welded, kuomarara kwepamusoro kunodiwa zvakare.
(3) Zvakanaka welding kuita uye kutonhora kuumba kuita.
(4) Kudzikira kutonhora brittle shanduko tembiricha.
(5) Good corrosion resistance.
3. Kuumba maitiro epombi yakakoshwa
(1) Yakaderera kabhoni: nekuda kwezvakanyanya zvinodikanwa zvekuoma, weldability uye kutonhora kuumba kuita, iyo kabhoni yemukati haipfuure 0.20%.
(2) Manganese based alloy element inowedzerwa.
(3) Kuwedzerwa kwe niobium, titanium kana vanadium: shoma shoma ye niobium, titanium kana vanadium inoumba yakanaka carbide kana carbonitride musimbi, iyo inobatsira kuwana zviyo zvakanaka zveferrite uye kuvandudza simba uye kuoma kwesimbi.Mukuwedzera, kuwedzera chidimbu chemhangura (≤ 0.4%) uye phosphorus (inenge 0.1%) inogona kuvandudza kusagadzikana kwekuora.Kuwedzera huwandu hushoma hwezvisingawanzo zvinhu zvepasi zvinogona kubvisa sarufa negasi, kuchenesa simbi, uye kunatsiridza kuoma uye kuita basa.
