What is ASTM 4140 steel Bar/Tube? AISI 4140 Alloy Steel Bar/Tube Relevant Standards

ASTM 4140 steel is also commonly referred to as a chromoly steel, or chrome moly steel. ASTM 4140 steel Bar/Tube is similar to 4140 steel which has a higher carbon level (0.28-0.33%), giving 4130 material improved weld ability, at the expense of through thickness strength.

AISI Alloy 4130 Steel Supply Range

4130 Steel Round Bar: diameter 8mm – 3000mm
4130 Steel Plate/Flat Bar: thickness 10mm – 1500mm x width 200mm – 3000mm

Hardening of AISI 4130 Alloy Steel

The steel 4130 should be constituents transformed to austenite – at 1500 to 1600 º F (815 to 870 º C). The actual temperature is a function of chemical composition within the analysis range, section size and cooling method.

Application of 4130 Steel

ASTM 4140 steel Bar/Tube is mainly used in Commercial aircraft, aircraft engine mounts, Military aircraft, Automotive, Machine tools, Hydraulic tools, Auto racing, Agricultural and defense industries etc.
