OTAI Steel is 8620RH Alloy steel stockholders and suppliers from china. OTAI SPECIAL STEEL are AISI 8620RH steel suppllier.

AISI 8620RH alloy Steel is a high quality specified hardenability bands Alloy Structural steel, It belong to the high quality low carbon,Low alloy chromium, molybdenum, nickel case hardening steel. Oil Quenched & Tempered Hardenss is 28-34 HRC. Moreover, AISI 8620RH steel Annealing delivery hardenss less than 250HB.

AISI 8620RH Alloy structural steel properties is a Nickel chromium molybdenum alloy steel specification. Furthermore, 8620RH With a lower carbon content range, So AISI 8620RH alloy steel have good weldability. And AISI 8620RH Steel is equivalent to Din 21NiCrMo2 | W-Nr 1.6523, GB 20CrNiMo, BS 805M20, NF 20NCD2,JIS SNCM220 Steel. Most applications can replace each others

Heat treatment Related
  • Annealing of 8620RH Alloy structural steel

Slowly heated to 850 ℃ and allow enough times, let the steel to be thoroughly heated, Then cool slowly in the furnace. The 8620RH alloy steel will get MAX 250 HB （Brinell hardness）.

  • Hardening of 8620RH Alloy structural steel

Heated slowly to 880-920°C, Then after adequate soaking at this temperature quench in oil. Temper as soon as tools reach room temperature.
