“…3,4 Low carbon steels are of high strength and good formability. 5,6 TATA steel has developed a new micro-alloyed ferritic hot rolled steel with the commercial name of XPF for use in automotive chassis and suspension elements. XPF800 comprises single-phase ferrite but lacks of containing complex phases, which is why it has the characteristics of high strength and good formability.…”

This study investigates the friction stir welding properties and resulting microstructural and mechanical properties of XPF800 steel, which is commonly used in automotive chassis and suspension components. The welding parameters were optimized with a tungsten carbide (WC) tool at a downforce of 11 kN, traverse speed of 95 mm/min, and rotating speed of 750 rpm. Microstructural analysis was conducted using scanning electron microscopy (SEM), optical microscopy (OM), and Energy Dispersive X-ray Spectrometry (EDS). Mechanical properties were evaluated through tensile, Charpy impact, and microhardness tests. Results showed that acicular ferrite formed in the stir zone, contributing to an increase in strength, with a maximum hardness of approximately 350 HV0.1. However, the heat affected zone (HAZ) experienced softening, resulting in a decrease in both tensile strength and hardness by approximately 8% and 20%, respectively, compared to the base material.

“…Advanced high strength steel and high strength low alloy (HSLA) steels are commonly used in the automotive industry due to their high mechanical properties. 3–7 However, high strength brings about low formability properties. 4 These steels have such hard structures as martensite and bainite, thereby their formability is limited.…”

In this study, the effect of gas metal arc welding on the mechanical and microstructure properties of hot-rolled XPF800 steel newly produced by TATA Steel has been investigated. This steel finds its role in the automotive industry as chassis and seating applications. The microstructure transformation during gas metal arc welding has been analyzed using scanning electron microscope, optical microscope, and energy dispersive X-ray spectrometry. Tensile, Charpy impact, and microhardness tests have been implemented to determine the mechanical properties of welded samples. Acceptable welded joints have been obtained using heat input in the range of 0.28–0.46 kJ/mm. It has been found that the base metal hardness of the welded sample is 320 HV0.1. On account of the heat-affected zone softening, the intercritical heat-affected zone hardness values have diminished ∼20% compared to base metal.
