**螺栓所用材料的比較大抗拉強(qiáng)度與淬火處理有很大關(guān)系，40Cr淬火處理后一般較難達(dá)到10.9S級(jí)**螺栓的材質(zhì)要求，在不是很?chē)?yán)格的檢驗(yàn)中，可以根據(jù)淬火處理后的表面硬度來(lái)判斷材料的比較大抗拉強(qiáng)度。除了處理工藝中的性能不同外，材質(zhì)不同的**螺栓，其在高應(yīng)力狀態(tài)下的延遲性斷裂性能也是有所不同的。 </p> <p> 40Cr**螺栓主要用于螺栓球節(jié)點(diǎn)網(wǎng)架中，其設(shè)計(jì)強(qiáng)度一般為390MPa(d>=30mm)或者430MPa（d<30mm)，使用中不存在很高的預(yù)拉應(yīng)力。當(dāng)用于要施加很高預(yù)拉力的情況時(shí)，要注意了解和保證其延遲性斷裂性能。20MnTiB**螺栓的延遲性斷裂性能好于40B的。
