The next steel generation for forged components in the drive train might be bainitic steels with an optimized microstructure with respect to cyclic behavior.

Cost-Saving Steels for Forging Automotive Parts Forging

Grain structure of the steel 16MnCr5mod following air cooling from the forging heat (H2). The bainitic steel 16MnCr5mod (H2) which was co-developed with steelmaker GMH allows the mechanical properties of heat-treatable steels to be achieved with cost-effective cooling from the forging Development of High Toughness Bainitic Microalloyed Development of High Toughness Bainitic Microalloyed Forging Steel 980883 The influence of chemical compositions and forging conditions on mechanical properties of forged bainitic steels were studied. Manganese and chromium are useful to produce bainite structure while carbon and vanadium are good to control the mechanical properties of the steels. Ferritic-Bainitic (FB) Steel - WorldAutoSteelFB steels sometimes are utilized to meet specific customer application requirements that require Stretch Flangeable (SF) or High Hole Expansion (HHE) capabilities for improved edge stretch capability. FB steels have a microstructure of fine ferrite and bainite. Strengthening is obtained by both grain refinement and second phase hardening with bainite. Figure 2-14 shows the microstructure []

Forging with Hybrid Steel 2020-10-05 FORGE

Oct 05, 2020 · Forging with Hybrid Steel A relatively new family of steel grades, called Hybrid Steels, is well-suited to meet the demands of high-stress, high-temperature applications in which mechanical and fatigue strength are critical. like dispersion-hardening microalloyed or low-carbon bainitic grades. Consequently, design engineers switch to quench High strength low alloy (HSLA) steels. - Knowledge These bainitic steels are particularly interesting for structural reinforcement parts, wheels, chassis parts and truck frames. The synergetic interaction of Mo with microalloying elements like Nb and Ti has also led to the development of ultrahigh-strength ferritic steels. The strength in these steels is gained by massive precipitation hardening.

Low and Medium Carbon Advanced High-Strength

precipitation hardening ferritic/pearlitic (PHFP-M) steels and bainitic steels subjected to hot-forging and then controlling cooling were developed to eliminate the additional Q&T treatment [14]. Although both the steels are applied to the automotive powertrain and chassis forging parts, their mechanical properties are inferior to those of Q New Bainitic Steels for High Strength Components for bainitic structures capable of being produced by cold heading or hot forging without final heat treatment, new low carbon grades microalloyed with niobium have been developed. EXPERIMENTAL PROCEDURE The new grades presented in this paper were developed following procedures established at the Mittal Steel Europe R&D Centre dedicated to long New Forged SteelS EnErgy-EfficiEnt SolutionS for Forging is one of the mature disciplines of automotive and mechanical engineering, that is a widespread opinion. Apart from advances in forging technology there are significant developments concerning steels for forging applications. Thus, high-strength ductile bainitic steels (HDB steels

Sophisticated Vanadium Vanitec

High Strength Forging Steels. Vanadium has been used for many years in high strength microalloyed forging steels. Downsizing of engine components has pushed the performance requirements of these components. Vanadium is finding use in new air cooled steels with bainitic microstructures. Find out how vanadium works in these new steels. Special steels Ascometal:Steels allowing heat treatment within the hot forging process (bainitic and AFP steels) VITAC ® , SUPERVITAC ® :steels with improved machinability ASCOFLEX ® :Cost saving, adaptable case-hardening grade with properties equivalent to molybdenum grades. Steels:Processing, Structure, and Performance - George Low carbon sheet steels, together with strengthening mechanisms, developments in microalloyed forging steels, steels with bainitic and a variety of ferritic microstructures, quench and tempered steel performance, high-carbon steels for rail and ultra-high strength wire, and the causes of low toughness and embrittlement are all discussed in new

Use of bainitic steels - Harry Bhadeshia

The range of bainitic alloys available commercially includes ultra-low carbon bainitic steels for high weldablity, very high strength steels competing with the quenched and tempered martensitic alloys, creep resistant steels which have now been used for decades in the power generation industries, forging steels which are better than martensitic alloys because they require mush less processing, inoculated Vanadium Effect on a Medium Carbon Forging Steelbainitic steels are designed to provide suitable bainitic microstructure after hot forging or rolling by natural cooling. As the precipitation of V carbides does not occur during the bainitic transformation, the use of V is not as extended in these grades as in the more conventional ferritic-pearlitic steels.Critical Assessment 22:bainitic forging steelsbainitic forging steels In a condensed manner, the aforementioned strategies are alreadyexploitedinacommercialway.Someoftherecent steel developments and commercial available bainitic for-ging steels are shown in Table 1 .
