Chromium - vanadium steel wire rod, wire and springs - high duty ground wire - hardened and tempered - specification.
建议对磨削后磨削面呈蓝黑色的弹簧再一次回火处理并检查是否存在缺陷。
It is suggested that the springs having bluish dark color grinding face after grinding should be tempered once more and inspect existing defects or not.
分析了国产油淬火-回火弹簧钢丝的各种质量缺陷，并提出了相应的改善措施。
To analyze every quality defeCts Of oil-tempered spring steel wire made in China, put forward appropriate improvement measures.
弹簧为低应力、油回火、螺旋缠绕在整体钢轴上扭力型弹簧。
Springs shall be low-stress, oil tempered, helical wound, torsion type on continuous shaft, Solid CRS or tubular as required.
在应变疲劳曲线上，弹性线和塑性线的交点随弹簧钢回火后硬度的升高而向低循环寿命移动；
The point of intersection of elastic line and plastic line moves toward the low cycle life with the hardness of the spring steel raised after tempering from the strain fatigue curve.
