Processing characteristics of SPA-H weathering steel plate

Posted:2021-01-13 13:55:10

SPA-H weathering steel plate generally refers to the alloy cast iron with Ge content between 11% - 30%. It is an important branch of anti-wear materials. SPA-H weathering steel plate has high hardness, high heat resistance, high wear resistance and high chemical stability. Good properties make SPA-H weathering steel plate widely used in production and life.

Processing characteristics of SPA-H weathering steel plate:
(1) SPA-H weathering steel plate has low thermal conductivity, poor plasticity, large shrinkage and poor casting performance. Therefore, attention should be paid to the problem of casting feeding.

(2)The riser of SPA-H weathering steel plate is not easy to be cut off, so side riser or easy to cut riser is used in modeling.

(3) The pouring temperature of SPA-H weathering steel plate should be low.
