X60NiMnCr13-5-3 is defined as a Fe - 12.5Ni - 4.5Mn - 3.5Cr - 0.6C austenitic type steel with a high thermal expansion, fastener material used for assembly of light alloy components working at high temperatures.

X60NiMnCr13-5-3 steel displays a good feature with a coefficient of expansion close to that of aluminum. Its mechanical properties can be enhanced by thermal treatment and further step by work hardening.
Fasteners used for assembly of light alloy components working at high temperatures. 
Distribution hollow tubes for valveless engines with pistons and cylinders. 
Precombustion chambers fitted to light alloy piston heads for diesel engines.
