Cr5Mo1V
Material Name: Die Steel
Material Grade: Cr5Mo1V
Material Standard: GB/T1299-2000 Cr5Mo1V an air quenching tool steel, hardened with the deep space of performance, which requires quenching and tempering must maintain its shape after the mold is extremely useful complexity. As the air quenching the steel deformation caused by oil quenching system only about manganese tool steel 1 / 4, wear resistance between the manganese-and high-carbon high-chromium type tool steel between the toughness of any kind is good, particularly for good wear resistance also requires a special tool for good toughness, is widely used in cutting die and the forming mold, roll, punch, rolling die and rolling die, but also for certain types of shears, and blades .
Dimensions:
Forged yuan Φ50 ~ Φ280 forging plate 20 ~ 80 × 40 ~ 400 Forged board 80 ~ 300 × 410 ~ 610
Uses:
Die for a variety of hardware, and bear a greater impact on large, complex red set mode.
Factory state:
Ball annealing HB ≤ 230
Chemical composition (%)
Standard: Gb/T1299-2000 C: 0.95/1.05 Mn: ≤ 1.00 Si: ≤ 0.50 Cr: 4.75/5.50 P: ≤ 0.025 S: ≤ 0.020 Mo: 0.90/1.40 V: 0.15/0.50
Feature
1, air quenching tool steel hardened with a deep space of performance,
2, high wear-resistant line, micro-deformation, high hardenability, high compressive strength,
3, Cr12 steel carbide distribution more uniform.
Heat treatment
Slow cooling annealing :1,800-850oC 2 spheroidizing
Air-cooled quenching :940-960oC
Tempering :180-220oC cooled HRc = 60-64 510-520oC cooled HRc = 57-60
Physical properties Cr5Mo1V critical temperature of steel are shown in Table 2-4-2, the density of 7.84t/m3; quality of specific heat cp is 460.55J / (kg · K); elastic modulus 203000MPa.
