Tempering stability of X80 steel is higher,its mechanical properties is stable,in addition,mechanical properties showed certain regularity along with tempering temperature variety. At 650℃ tempering,strength and plasticity change obviously.
试验结果表明,X80管线钢在930℃时已经能够完全奥氏体化,并获得板条状马氏体组织,且X80管线钢回火稳定性较高,力学性能相对稳定,并且随回火温度变化呈现出一定的规律性,在650℃回火时,其强度和塑性变化较为明显。

研究X80实物弯管得出，其直管段有比弯曲段低的回火稳定性和优良的强韧特性。
The testing results of X80 pipeline bends show that the tangent end has lower temper stability and more excellent strength-toughness than bent region.
而最表层由于获得完全细化的马氏体组织，拥有较好的回火稳定性，与未偏磨面表层硬度相当。
However, because of fully granin refinement of martensite and good perfornance of temper resistance , the hardness of outer surface of worn side is equal to that of non-worn side.
由于马氏体这一淬硬钢主要成分的不稳定性，使得回火成为可能。
Tempering is possible because of the instability of the martensite, the principal constituent of hardened steel.
