is a kind of structural alloy steel under the ASTM A29/A29M-04 standard, and it is a common low carbon alloy carburizing steel. ASTM5115 has high cold deformation and plastic,good weldability and good machinability under the condition annealing.
ASTM5115 is used as the carburized parts whose working speed is higher and toughness of section of heart is not large.Such as bushing, crank pin, piston pin, piston ring, coupling, and the working speed is higher circle of gear, CAM, shaft and bearing, etc., ship host with screw, small locomotive parts, steam turbine set of ring, etc.
