Introduction:
9sicr steel is low alloy cutting steel, but also often make cold work mould parts, the effect is very good. It than chrome steel (Cr2 or 9 Cr2) have higher hardenability and hardenability and have high tempering stability. The steel quotations from the former Soviet union as early as 9 xc, once known as 9 crsi steel. Composition and performance with 9 xc are exactly the same. In our country has a long history.

Equivalent Grades:
Grade | C | Si | Mn | Cr | P | S |
9SiCr | 0.85~0.95 | 1.20~1.60 | 0.30~0.6 | 0.95~1.25 | ≤0.035 | ≤0.035 |
Mechanical Properties:
The steel forging performance is good, because of easy
decarburization, need in the neutral atmosphere or protective
atmosphere furnace heating. Conditioning treatment with heat
forging, can obtain fine tempered sorbite structure, simplify the
process, time saving, both good machinability, and the ideal heat
treatment group.
Heat treatment specification and metallographic
organization:
Specification: heat treatment quenching sample 820 ~
860 ℃, oil cooling.
Low delivery status: steel in annealing state
delivery.
Low point temperature (approximation)
Ac1 = 770 ° C, 730 ℃, Accm Ar1 = = 730 ° C.
Low thermal specification
Needs in the neutral atmosphere or protective atmosphere furnace
heating, preheating temperature of 700 ~ 80 ° C o for the first
time, holding time 1. 0 ~ 1.5 h, the second 850 ~ 900 ° C, 2
min/mm, time of heat preservation heat insulation at 100 ℃ or less
after speed up to 1100 ~ 1150 ℃, holding time 1.0 ~ 1.5 min/mn.
Should frequently turning of billet in the process of heating,
uniform heat, fully burned. The forging temperature 1050 ~ 1100 °
C, repeated double cross to the upsetting forging, after forged
alloy carbide grade level 2 or less.
Application
9 sicr alloy tool steel can be used to make complex shape and small
deformation, high wear resistance, low speed cutting tools, such as
drilling, thread tools, reamer, die, tap, thread rolling plate and
screw rolling wheel, etc. (plastic die steel, can be used in the
top bar, create size increase, complicated shape and high accuracy
requirement of plastic film.
