Product introduction
The tensile strength and plasticity are low, but the casting performance and shock absorption performance are good, and the matrix is pearlite, which needs artificial aging treatment.
Chemical composition: carbon content of 2.8% to 3.8%, silicon content is 2.2% 2.8%, manganese content is 0.3 0.5%, phosphorus content of 0.15% or less, sulfur content 0.12% 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.
