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.

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 **0 ~ **0 ℃, oil cooling.
Low delivery status: steel in annealing state delivery.
Low point temperature (approximation)
Ac1 = **0 ° C, **0 ℃, Accm Ar1 = = **0 ° C.
Low thermal specification
Needs in the neutral atmosphere or protective atmosphere furnace heating, preheating temperature of **0 ~ *0 ° C o for the first time, holding time 1. 0 ~ 1.5 h, the second **0 ~ **0 ° C, 2 min/mm, time of heat preservation heat insulation at **0 ℃ or less after speed up to ***0 ~ ***0 ℃, 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 ***0 ~ ***0 ° 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.
