Description

Introduction

Carbon steels are those that have carbon as the specific alloying element. They contain up to 0.4% silicon and 1.2% manganese. The residual elements such as copper, molybdenum, aluminium, chromium and nickel are also present in these steels.

Chemical Composition

The chemical composition of AISI 1070 carbon steel is outlined in the following table.

Element Content (%)
Iron, Fe ~ 98
Carbon, C 0.65 – 0.75
Manganese, Mn 0.60 – 0.90
Sulfur, S 0.050 (max)
Phosphorous, P 0.04 (max)

HEAT TREATMENT OF AISI 1070

  • Normalize by heating to 843° to 899°C before air cooling
  • Anneal by heating to 843° to 857°C before air cooling
  • Harden by heating to 788° to 829°C before oil quenching
  • Temper to appropriate strength and hardness, from 204° to 704°C
