style="text-indent:25px">彈簧鋼可以在低溫回火的板條狀馬氏體組織下使用，有足夠強(qiáng)度和優(yōu)良的綜合力學(xué)性能，尤其是塑性、韌性極好，重慶抗疲勞彈簧鋼帶。日本研究開發(fā)的幾種強(qiáng)度較高度彈簧鋼，如uhs1900、vhs2000，重慶抗疲勞彈簧鋼帶，重慶抗疲勞彈簧鋼帶、nd120s、nd250s等，碳含量均在0.40%左右。合金元素在彈簧鋼中的主要作用是提高力學(xué)性能、改善工藝性能及賦予某些特殊性能（如耐高溫、耐蝕）等。很多彈簧鋼以硅為主要合金元素，它是對(duì)彈減抗力影響較大的合金元素，這主要是由于硅具有強(qiáng)烈的固溶強(qiáng)化作用；同時(shí)，硅能抵御滲碳體在回火過程中的晶核形成和長大，改變回火時(shí)析出碳化物的數(shù)量、尺寸和形態(tài)，提高鋼的回火穩(wěn)定性。國內(nèi)鋼材牌號(hào)中wsi為1.8%～2.2%，是現(xiàn)有標(biāo)準(zhǔn)中含硅較高的彈簧鋼。但硅含量如果過高，將促進(jìn)鋼在軋制和熱處理過程中的脫碳和石墨化傾向，并且使冶煉困難和易形成夾雜物，因此，過高硅含量彈簧鋼的使用仍需慎重。為了保持不銹鋼所固有的耐腐蝕性，鋼必須含有12%以上的鉻。重慶抗疲勞彈簧鋼帶</p><div
