Product introduction
According to GBT 9441-2009, spheroidization rate and graphite morphology were determined. The matrix was mainly pearlite and ferrite. The number of edge graphite balls is large, the proportion of pearlite is low, the proportion of cementite is less than or equal to 3%, and the dispersion distribution;
Chemical composition: carbon content of 3.0% to 3.8%, silicon content is 2.2% 3.2%, manganese content is 0.3 0.6%, phosphorus content of 0.05% or less, sulfur content 0.02% or less.
Sampling reference position
Round bar: Take 1/2 radius position
Rectangular or square bar: take the diagonal 1/4 position
See the following figure as the basis for the determination of mechanical resistance and metallographic structure.
