1.2355 | ASTM S7 Hot Work Tool Steel Quick
Details1: AISI S7 steel introduction
AISI S7 tool steel is a shock-resistant air hardening
steel. AISI S7 steel has exceptional impact properties plus the
highest hardenability of shock resisting grades of tool steel.
Steel S7 also possesses good softening resistance at high
temperatures which gives it hot work capabilities. Since S7 steel
hardens in air, it is also safe and stable in heat treatment.
AISI S7 tools steel has an unusual combination of
properties, making it suitable for an extremely wide range of tool
and die work - where shock-resistance, medium hot-work properties,
or ease of machining and heat-treatment are most important. 2:

AISI S7 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. 5: AISI S7 steel

6. AISI S7 Tool Steel Heat TreatmentAnnealing
Anneal in a protective atmosphere. Heat rapidly to 1500
to 1550°F and hold at that temperature for one and one-half hours
for each inch of greatest thickness. To obtain best machining
properties, cool slowly to 1000°F, and then air-cool. This
annealing procedure should produce a hardness of Brinell 197
max.Stress Relief S7 steel Material: When desirable to relieve the
strains of machining, heat slowly to 1050°-1250°F, allow to
equalize, then cool in air.Hardening Preheat:
Warm steel S7 slightly before charging into the preheat furnace
1200°-1300°F, prior to hardening.Harden: 1750°F. Quench S7 tool
steel in air if cross section is 2-1/2″ or smaller; sections 2-1/2″
to 6″ should be oil quenched to black (1000°F) followed by air
cooling to 150°F. Larger cross sections of S7 steel should be oil
quenched to 150°F. Quench: Quench in still air or
dry air blast. Temper: Tool steel S7 is normally
tempered one hour per inch of section thickness to desired heating
rate of 2 hours per inch. Cool in air to room temperature between
the two tempers. The tempering temperature varies according to the
intended use. Suggested: For cold-working and similar applications,
the recommend400°-500°F. Hot working applications: apply a
tempering temperature of 900°-1000°F. Never temper at less than
400°F. 7: Delivery condition For hot forged
or hot rolled bar, usually the delivery condition is hot forged or
rolled, annealed, rough turned. For hot forged
plate, usually the delivery condition is hot forged, annealed,
milled surface. For hot rolled plate, usually the
delivery condition is hot rolled, annealed, black surface.
