DEVELOPMENT OF MICRO-ALLOYED HIGH STRENGTH WELDED STEEL TUBES FOR TWO AND THREE WHEELERS

摘要

A series of high strength precision welded tubes have been developed using Microalloyed steel possessing high strength and good weldability compared to conventional steels adaptable to automobile parts for two and three wheelers. An addition of small amount of alloying element like. Ti, Nb and Vanadiun in low carbon steel shows a significant result in grain refining and precipitation hardening of low carbon steel. Tabel-1 shows the chemical composition of steel for present invention.
