The result shows that the decarburizationdepth increases with the increase in temperature and holding time for the two steels.
结果表明，两种弹簧钢的脱碳深度随提高加热温度和增加加热时间增大。

For grade 1, no complete decarburization shall be present. The depth of partial decarburization at any point on the periphery shall not exceed the value in table 1.
对于等级1，没有完整的脱碳。外围任何点的部分脱碳深度不得超过表1中的数值。

It analyzed main factors of arising spectrum analysis error which including specimen decarburization layer depth, surface roughness, describing, etc.
