1.	What is the amount of carbon present in low carbon steel?(a) Less than 0.5%(b) Less than 0.7%(c) Less than 0.4%(d) Less than 0.2%The question was asked at a job interview.My doubt is from Classification of Foundry Metals and Alloys in portion Foundry Introduction & Materials of Casting-Forming-Welding II
Answer» The correct choice is (d) Less than 0.2% Best explanation: Low carbon steel has the LOWEST AMOUNT of carbon mixed with IRON in the ALLOY. The amount of carbon present in low carbon steel is less than 0.2% and that of medium carbon steel has carbon COMPOSITION of about 0.2% to 0.5%.
