大慶45#精密鋼管終身質保 <大慶>金帝鋼管

精(jing)(jing)密(mi)(mi)鋼(gang)(gang)管(guan)(guan)(guan)(guan)為什么要這樣？淬火是將精(jing)(jing)密(mi)(mi)光亮管(guan)(guan)(guan)(guan)加溫(wen)保溫(wen)后(hou)(hou)，在水、油或(huo)其(qi)他無機(ji)(ji)鹽、有機(ji)(ji)水溶液等(deng)淬冷物質(zhi)中(zhong)迅速冷卻(que)。淬火后(hou)(hou)精(jing)(jing)密(mi)(mi)光亮管(guan)(guan)(guan)(guan)發硬，但同時變脆。以(yi)便減少精(jing)(jing)密(mi)(mi)光亮管(guan)(guan)(guan)(guan)的(de)脆性，將淬火后(hou)(hou)的(de)精(jing)(jing)密(mi)(mi)光亮管(guan)(guan)(guan)(guan)在高過室內溫(wen)度(du)而小于650℃的(de)某(mou)一(yi)(yi)適當溫(wen)度(du)進行(xing)長(chang)期(qi)的(de)保溫(wen)，再進行(xing)冷卻(que)，這類加工(gong)工(gong)藝稱之為回火。精(jing)(jing)密(mi)(mi)鋼(gang)(gang)管(guan)(guan)(guan)(guan)產(chan)品質(zhi)量穩定，價(jia)格合理(li)，交貨及(ji)時，“質(zhi)量優先、一(yi)(yi)諾(nuo)千(qian)金、以(yi)誠為本、用戶至上”的(de)原則，滿足各行(xing)各業對精(jing)(jing)密(mi)(mi)鋼(gang)(gang)管(guan)(guan)(guan)(guan)、軸承鋼(gang)(gang)管(guan)(guan)(guan)(guan)、無縫方矩管(guan)(guan)(guan)(guan)產(chan)品的(de)需求。
