Cast Iron Railway Brake Shoe Replacement For Heavy Duty Truck
cast iron brake block
Our cast iron brake block enjoys many advantages including
hardness, impact strength and so on. It consists of two parts, the
cast iron and the steel support. Both the surface and core of the
cast iron have the hardness within the range of 197< HB< 255.
When facing subsequent impacts to the brake block or brake shoe,
the steel support must remain intact and attached to the iron
places. The connection bridge may possibly become detached but
should not show any soundness defects. Separated from the brake
shoe, the support must be able to withstand the bend test with
cracking or breaking.
