Steel capped at 1.3% carbon maximum finds various uses, though 0.4% carbon steel is unsuitable for manufacturing___________________?
Show answer Hide answer
Answer: C. Chisels
Explanation
Chisels require high cutting edge hardness and wear resistance achievable only with high carbon tool steels. A low carbon steel containing zero point four percent carbon lacks sufficient hardness for impact cutting tools. Quenching a medium carbon steel will not yield the hard martensitic structure needed for a chisel edge. Chisels are hand or machine tools used for cutting and carving hard materials like wood and metal. Tool steels typically contain higher carbon concentrations often exceeding zero point eight percent. Heat treatment processes like quenching and tempering are mandatory to develop tool hardness.
Using incorrect low carbon steels for cutting tools results in rapid edge blunting and bending. Engineering workshops select appropriate alloy grades based on specific tool loading requirements. Proper material selection prevents workplace accidents caused by failing hand tools. Nuts are low stress fasteners commonly manufactured from affordable low or medium carbon steels. Bolts require moderate tensile strength easily provided by medium carbon steel grades. Studs are threaded fasteners frequently produced from standard structural carbon steel bars.
