Y15Pb lead-containing easy-to-cut steel, good machinability

Alloy steel Y15 is use for civil and industrial construction, means of transport, electionics and medical use

Y12Pb belongs to free-cutting structural steel, and the implementation standard is GB/T 8731-1988.

Y12 is the code name of a steel. Y12 is divided into two types, sulfur-phosphorus composite low-carbon free-cutting steel and free-cutting steel.

1117 is used in automatic screw machines for manufacturing numerous parts requiring considerable machining and close tolerances, along with a smooth finish. ​

Cr20Ni35 alloy is a single-phase austenitic structure

Cr20Ni80 alloy is single-phase austenite structure

Cr15Ni60 is an ideal material, it has good ductility,workability and weldability under high temperature and seismic strength.

The alloy meets the requirements of ASTM B 171 C71500 and ASTM B 151 C71500.
