1.1210 Carbon Structural Steel
Detailed introduction:
1) High strength carbon structural steel with moderate machinability, low cold deformation plasticity, poor weldability, and no temper brittleness during heat treatment,
But the hardenability is low, with a critical diameter of 13 * 30mm in water, and there is a tendency for cracking during water quenching. This steel is usually subjected to normalizing or quenching tempering, or high frequency
Use after surface quenching and other heat treatments.
(2) Supply status and hardness: Untreated state, hardness ≤ 241HBW; Annealed state, hardness ≤ 207HBS.
(3) Chemical composition (mass fraction,%)
C 0.47~0.55、Si 0.17~0.37、Mn 0.50~0.80、P≤0.035、S≤0.035、
Ni≤0.30、Cr≤0.15、Cu≤0.25、.
(4) Refer to the corresponding steel grade German DIN standard material number 1.1213, German DIN standard steel grade Cf53, and Chinese GB standard steel grade 50
British BS standard steel grade 060A52, French AFNOR standard steel grade XC48TS, French NF
Standard steel grade C50, Italian UNI standard steel grade C53, Belgian NBN standard steel grade C53, Swedish SS standard steel grade 1674
American AISI/SAE/ASTM standard steel grade 1050, Japanese JIS standard steel grade S50C/S53C, and International Organization for Standardization ISO standard steel grade C50E4.
(5) Critical point temperatures (approximate values) Ac1=725 ℃, Ac3=760 ℃, Ar3=721 ℃, Ar1=690 ℃
(6) Normalization standard temperature: 830 ℃± 10 ℃, air cooling.
(7) Standard quenching and tempering: quenching temperature 830 ℃± 10 ℃, water and oil cooling; Tempering temperature 600 ℃± 10 ℃, cooled with water and oil.
(8) Suitable for manufacturing mechanical parts with dynamic loads, low impact loads, and good wear resistance requirements, such as forged gears, shaft friction discs, machine tool spindles, etc
Engine spindle, rolling mill, tie rod, spring washer, etc.
