Our high-performance cast iron brake block, sourced from Hebei, China, is engineered to deliver exceptional advantages such as remarkable hardness and outstanding impact strength. The product is meticulously crafted with two integral components: the robust cast iron and a durable steel support. With a precision-engineered surface and core, the cast iron's hardness consistently falls within the ideal range of 197, ensuring unparalleled reliability and performance in demanding railway applications.< 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.
Chemical compositions of cast iron: Our cutting-edge cast iron boasts an optimal composition, featuring Carbon: 3.0-3.5%, Phosphorus: 1.3-1.5%, Silicon: 1.5-2.0%, Sulphur: 0.1-0.15%, and Manganese: 0.5-0.8%. This precise blend is designed to maximize durability and effectiveness.
Chemical compositions of steel support: C % < 0.13%, S % < 0.062%, P % < 0.062%
