中山·佛山·55Si2Mn合金彈簧鋼+++深圳、東莞、珠海、中山、佛山、廣州、石龍、虎門、長安、道窖、塘下、樟木頭、清溪、茶山等。
產品介紹:55Si2Mn彈簧鋼硅和錳提高彈性強度和屈強比,提高淬透性,抗回火穩定性和抗松弛穩定性,過熱敏感性也較小,但脫碳傾向較大,尤其是硅與碳含量較高時,碳易于石墨化,使鋼變脆。55Si2Mn彈簧鋼用作汽車、拖拉機和機車上的減振板簧和螺旋彈簧、氣缸安全閥簧,還可用作250℃以下使用的耐熱彈簧。●化學成份:碳C:0.52~0.60硅Si:1.50~2.00錳Mn:0.60~0.90硫S:≤0.035磷P:≤0.035鉻Cr:≤0.35鎳Ni:≤0.35銅Cu:≤0.25
