Daftar Isi:
- API Steel 5L Grade B is pipe which is made and produced based on API standard that is American Petroleum Institute which this pipe has carbon max 0,3%, Mn max 1,2%, P max 0,05%, S max 0,06% (from: Independent Pipe And Supply Corp.) that is included in middle carbon steel. In book (Wiryosumarto,2000) mentioned middle carbon steel is having level of good enough weld ability compared to high carbon steel. There are some factor influences strength of metal for example carbon grade contained by the metal, height of temperature heating (temperature of austenite), detention time ( homogeneity austenite), and cooling speed. Purpose of performed by this research is to increase strength of material API steel 5L Grade B with Annealing treatment. From result of research is obtained conclusion for heat treatment with temperature 750, 800, 850 oC consisted of by metal base district, HAZ and Las that for base metal from API steel 5L Grade B without heat treatment gotten best hardness.
