Bake Hardenable (BH) Steel 10/16/15 PKM 13 Bake hardening refers to increase in strength during paint baking, typically at 175 o C for 20 to 30 minutes. As in IF steels, BH steels also have very low carbon content. They are typically niobium stabilized so that niobium carbide is formed and precipitated at the grain boundaries. Increase in yield strength during paint baking occurs Bake Hardening Steel - an overview ScienceDirect TopicsThe new ferrous metals being introduced include the interstitial free (IF) steels, bake hardenable steels, transformation-induced plasticity (TRIP) steels, the high-strength low-alloy (HSLA) steels, dual phase (DP) steels and martensitic and manganeseboron steels, having yield strengths that vary from a low of 200 up to 1250 MPa. Bake hardening effect of the low strength interstitial This paper investigates the influence of pre-strain and temperature on the bake hardening (BH) effect of the low strength interstitial free (IF) steel with the yield strength of 137 MPa. The tensile specimens were pre-strained to 2-4-6 % at room temperature followed by baking at temperatures of 150-200-250 oC for 20 minutes. The BH strength was determined by a standard procedure based on the

Bake hardening of automotive steels - ScienceDirect

Jan 01, 2017 · Bake hardening (BH) steels are characterized by a significant increase (~10%) in yield strength (YS) after pre-formed component is subjected to the paint baking operation during manufacturing of various automotive body parts (outer door panels, outer skin of hood, fenders, and trunk (boot) lids, etc.) .This increase in strength is termed bake hardening response (BHR) and results in Comparison of the Microstructural Effects between the BH This work aimed to obtain microstructural changes due to the springback effect in order to compare two conventional high strength steels:the interstitial free steel (IF) and the bake hardening steel (BH). The mechanical characterization of the springback effect was performed by a mechanical forming testing called as the three-point air bending.
