Product introduction
9SiCr hot rolled steel round bars information
9 sicr 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.
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.
