ENGINEERING STEEL  

ASTM 4140 alloy steel is a chromium-, molybdenum-, and manganese-containing low alloy steel.

ASTM 1045 steel, normalized or hot-rolled: good weldability, machinability, high strength, and high impact properties.

ASTM 4340 steel is an ultra-high strength steel classified a medium-carbon, low-alloy steel.

ASTM 8620 alloy steel is a common, carburizing alloy steel. It can be heat-treated to adjust its mechanical properties.

S355J2 is fundamentally characterized by being a material that processes well.

AISI 4130 / UNS G41300 grade is a low alloy steel containing chromium and molybdenum as strengthening agents.

Commonly used for general engineering C-20 is suitable for applications such as bolts, shafts, spacers, hubs, base plates, brackets, fixtures and jigs.

18CrNiMo7-6 Gear parts exposed to highest stresses and wear conditions. Typical components include gears, planetary gears, plate wheels, drive pinions and shafts.

30CrNiMo8 is used for heavily loaded parts like shafts, crankshafts, screws, and high-temperature power industry components.
