yield-tensile ratio的意思|示意

The yield strength, yield tensile ratio and toughness are major quality indexes of steel pipe (board). However, it is quite difficult to determine them reasonably.

屈服强度、屈强比、韧性等是钢管(板)的主要质量指标，合理确定这些指标的数值有相当难度。

There is clearly changed on yield strength and ratio of yield and tensile strength and the main affecting elements is middle frequency heating temperature before coating.

管体屈服强度和屈强比有明显变化，其主要影响因素是防腐前的中频加热温度。

Quenching and tempering heat treatment are integrated in order to improve the mechanical properties of fasteners to meet the product requirements of tensile strength and yield ratio value.

热处理调质是为了提高紧固件的综合力学性能，满足产品规定的抗拉强度值和屈强比。

Pipeline steel adopting the spicular ferrite owns the better properties of forming and anti corrosion for its low ratio of yield strength and tensile strength and uniform microstructure.

由于低屈强比和组织均匀，管线钢采用针状铁素体组织可以具有较好的（管）成型性及耐腐蚀性。 用针状铁素体管线钢平板或卷板制造的焊管的力学性能彼此相差不大。

The creep-resistant, tensile strength and hardness are increased, but there's no obvious change on the elongation ratio and yield strength. Though the low temperature damping ca…

同时还提高了AZ91合金的高温抗蠕变性能和抗拉强度及硬度，但对屈服强度和伸长率影响不大，降低了合金的低温阻尼性能，但却增加了高温界面阻尼。

But the tensile strength will be reduced a little, and the yield ratio increased.

但抗拉强度将随卷曲温度的降低而有少量损失，而屈强比提高。
