technology:
Heat treatment standard: quenching at
**0℃, oil cooling; tempering at **0℃, water cooling, oil
cooling;
Metallographic structure: tempered
sorbite
Heat treatment:
1. Normalizing: Heat the furnace to
**0°C~**0°C, keep the thickest cross section per inch at this
temperature for one hour, and cool in air.
2. Heat to austenitizing at a temperature
of **0℃~**5℃, and keep the thickest cross section per inch
for one hour at this temperature
3. Normalizing or oil quenching, and
cooling to a maximum temperature of **1°C
4. Temper at a temperature that achieves
the following mechanical properties. The thickest cross-section
per inch is held for one hour at the tempering temperature, and
the tempering temperature range is **0 ° C ~ **0 °
C
5. For each heat treatment process, a heat
treatment chart must be drawn.
6. The mechanical property test shall be
carried out in accordance with the stipulations of ASTM. A***0.
The sample material used for the test shall be cut from the test
bar of the same furnace steel. The casting or forging represented
by the sample and the test bar shall be in the same furnace. The
test bar shall be heat treated in the same furnace together with
the charge.
7. The mechanical properties should meet
the following requirements: (Tested with a test bar, sampling
according to APT 6A, **0K standard) - Tensile strength minimum
lb/inch (**2) Yield strength minimum lb/inch **0.**0 (**8) 2
inches The minimum value of elongation is *5% and the minimum
value of section shrinkage rate is %*0. Brinell hardness HB**5 ~
take, the casting or forging represented by the sample and the
test bar must be in the same furnace, and the test bar should be
heat treated in the same furnace together with the
charge.
8. The mechanical properties should meet
the following requirements: (tested with test bars, sampling
according to APT 6A, **0K standard) - minimum tensile strength
lbs/inch (**2) minimum yield strength lbs/inch (**8) 2 inches
Minimum elongation %*5 Minimum shrinkage of section %*0 Brinell
hardness HB**5~**2
