The 9CrSi steel plate is an alloy tool steel and a low speed low alloy cutting tool steel. 9CsSi has brittleness and hardness, heat sensitivity and surface quenching tendency. The heat treatment of the 9CrSi steel plate is good and the use value will be improved.

chemical components:

Carbon C: 0.85~0.95
Silicon Si: 1.20~1.60
9CRSI round bar manganese Mn: 0.30~0.60
Sulfur S :≤0.030
Phosphorus P :≤0.030
Chromium Cr: 0.95~1.25
Nickel Ni: Allowable residual content ≤ 0.25
Copper Cu: Allowable residual content ≤ 0.30

9CrSi steel plate mechanical properties hardness: annealing, 241 ~ 197HB, indentation diameter 3.9 ~ 4.3mm; 187 ~ 229HB (for thread tools); quenching, ≥ 62HRC
[Applications]: Mainly used in the manufacture of low-speed cutting tools (such as woodworking tools, bench tools, drills, milling cutters, broaches, etc.) and measuring tools (such as calipers, micrometers, block gauges, templates, etc.). Measuring tool steel requires high hardness (62 ~ 65HRC), high wear resistance, sufficient toughness, high heat hardness (ie, the cutting tool can maintain high hardness at high temperature); to ensure the accuracy of measurement, the measuring tool is required The cutting tool steel has good dimensional stability.
