Description

Cast iron SCH35 is used: for the manufacture of various castings especially for critical applications — blocks and cylinder heads, liners, flywheels in transportation; heavy-duty parts working in compression (Bashmakov, columns) in the construction; heavy-duty frame presses, hydraulic cylinders in the machine tool industry, the most critical parts with the highest standards in diesel technology; heavy-duty parts with large variations in cross sections in chemical engineering, the most critical parts running on the wear of agricultural machinery; casting parts of valves and actuators to it; cast connecting parts for pipelines.

Note

Pearlitic cast iron.
