    ASTM A519 Seamless Alloy Steel Tubing

    AISI 8620 alloy Steel with Quenched and Tempered process cold drawn and cold rolled seamless tubes for rod and shaft

    Products Description:

    AISI 8620 alloy Steel is a high quality Quenched and Tempered 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. AISI 8620 steel Annealing delivery hardenss less than 250HB.

    AISI 8620 Alloy structural steel properties is a Nickel chromium molybdenum alloy steel specification. 8620 With a lower carbon content range, So AISI 8620 alloy steel have good weldability. AISI 8620 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 8620 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 8620 alloy steel will get MAX 250 HB (Brinell hardness).

    • Hardening of 8620 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.
