AISI 4130 Bar Chemistry:

AISI 4130 alloy steel is medium carbon, chrome moly alloy steel, containing 0.28-0.33% carbon, 0.80-1.10% chromium and 0.15-0.25% molybdenum. It is similar to AISI 4140 steel which has a higher carbon level (0.28-0.33%), giving AISI 4130 material improved weldability, at the expense of through thickness strength. This alloy steel bar exhibit good overall combinations of strength , toughness and fatigue strength.

AISI 4130 steel should be forged between 1230 to 950°C. The lower the finishing temperature from forging, the finer will be the grain size. If the 4130 alloy steel is forged at too low temperature, there is a risk of the formation of a non-uniform structure in certain areas of the forged part, necessitating a normalizing treatment, prior to further heat treatment.

Heat Treatment:

With proper heat treatment, AISI 4130 alloy steel bar can be machined. AISI 4130 steel is usually supplied as round bar commonly in the hardened and tempered condition.

Specification:

Round bar diameter range: 10mm-1000mm

Flat bar size thickness: 10mm-200mm

Surface finish: black, rough machined, peeled, turned or as required
