Annealing :
Heat slowly to 650-700°C. Cool in air.
Hardening :
EN41b is supplied ready heat treated. If further heat treatment is required
annealed EN41b should be heated slowly to 870-930°C and after adequate
soaking at this temperature quench in oil/polymer or water. Temper as soon
as tools reach room temperature.
Stress Relieving :
If machining operations have been heavy or if the tool has an unbalanced
section, remove stresses before hardening by heating up to 700°C,
equalise, then cool slowly.
Tempering :
Heat carefully to a suitable temperature selected by reference to a
tempering chart or table.
Applications :
Typical applications include connecting rods, extruders, valve stems, dies,
ring & plunger, Screw and barrel for injection moulding machines
