Mechanical properties of 35CrMo round steel

(1) Material characteristics: the steel has good machinability, after machining forming, cavity deformation and size becomes smaller, after heat treatment can improve the surface hardness, improve the service life of the mold. Adding a normalizing or annealing procedure before quenching and heating can further improve the mechanical properties of materials by refining grains and eliminating networked ferrite and banded structure.

The steel has high static strength, impact toughness and fatigue limit. Its hardenability is higher than that of 40Cr steel. It has high creep strength and rupture strength at high temperature. In cold deformation, the plasticity is medium and the weldability is poor.

(2) Supply status: normalization, annealing, high temperature tempering or delivery without heat treatment. Annealed state, hardness ≤ 229HbW.

(3) Chemical composition: according to standard GB/T 3077-1999, the chemical composition (mass fraction) of the steel: C0.32, Mn0.40% % ~ 0.40% ~ 0.70%, Si0.20% ~ 0.40%, Cr0.80, Mo0.15% % ~ 1.10% ~ 0.25%, S acuities were 0.035%, 0.035% or less, Ni P acuities were 0. 30%, C 0.25% or less.

(4) refer to the corresponding brand: German DIN material number 1.7220, German DIN standard number 34CrMo4, Chinese GB standard number 35CrMo, British BS standard number 708A37, British EN standard number 19B, French AFN0R standard number 35CD4, Italian UNI standard number 35CrMo4, Belgium NBN standard grade 34CrMo4, Sweden SS standard grade 2234, Spain UNE standard grade 34CrMo4, Japan JIS standard grade SCM432/SCRRM3, the United States AISI/SAE standard grade 4137; 4135.

(5) Mechanical properties: tensile strength ≤ 985Mpa, yield strength ≤ 335Mpa, elongation 12%, section shrinkage ≤45%, impact absorption energy ≤63J, impact toughness ≤78J/cm2

(6) Critical point temperature (approximate): AC1 =755°C, AC3 =800°C, AR3 =750°C, AR1 =695°C, MS =271°C

(7) complete annealing specification: annealing temperature 830 ~850°C, insulation 2 ~3h, furnace cold to 500°C, air cooling, hardness 197 ~ 229HbW.

(8) Quenching and tempering specifications: quenching temperature 850°C. Oil cooling, tempering temperature 550°C, water cooling or oil cooling. The blank thickness is 25mm, the tensile strength is 1000MPa, the yield strength is 850MPa, the elongation is 12%, and the impact toughness is 80J/cm2

(9) typical application example: suitable for large section aluminum, magnesium alloy die casting mold
