4130 Steel -- My ObservationsAISI 4130 is a chromium-molybdenum steel that is in general (aviation) use due to its well established heat-treating practices and processing techniques. AISI 4135 has a slightly higher carbon version of AISI 4130. AISI 4140 is a chromium-molybdenum steel that can be heat treated to higher strength levels or in thicker sections than AISI 4130.

In it's annealed state it is ductile as any steel, and hardens only to a mild level. Bend or break are difficult questions to answer, for one thing all metals break once they've reached their elastic limits, the other factor is the rate at which force is applied to the sample, the faster the force the sooner it will snap.
