DIN 15CrNi6 is the most representative grade of case-hardened steels. The present work analyses influence carburizing time on hardness specific steel. Specimens with similar chemical composition were heated at 900°C in liquid carbonaceous media for one, two, three and four hours, correspondingly. Then samples oil quenched tempered 180°C two hours. Microhardness was measured across carburized zo...

The importance of steel in manufacturing and construction over the past century cannot be over-emphasized easy accessibility couple with excellent mechanical properties make it preferable others. However, problem durability has posed a serious concern as majority application are meant for long term use. Several attempts have been made to improve increase carbon content low was found suitable ag...

Low carbon steel with content ranging from 0.15% to 0.3% cannot be hardened through quenching and tempering processes there is little no martensitic transformation occurring upon quenching. To improve the surface hardness, carburizing commonly employed. Through this treatment, composition of low-carbon altered by diffusion carbon, resulting in a hard outer casing good wear resistance. This work...
