1: 1141 steel introduction
ASTM1141 is high sulfur medium carbon free-cutting steel, which has better cutting performance. Compared with 45# steel, ASTM1141 can increase tool life by four times, increase productivity by 30%, and has higher strength and hardness.

4: 1141 steel mechanical properties
The mechanical properties mainly include tensile strength, yield strength, elongation, area or reduction, hardness, impact value, non-metalic inclusion etc. Different heat treatment, the mechanical properties will be different, such as normalized, tempered, QT. If you want to know the properties, kindly contact the salesman.
