Introduction of ***0 

    ***0 steel has high strength, hardenability, good toughness, small deformation during quenching, and high creep strength and durable strength at high temperature. It is used to manufacture forgings requiring higher strength and larger quenched cross section than *5CrMo steel, such as large locomotive traction gear, supercharger transmission gear, rear axle, highly loaded connecting rod and spring clip, and can also be used for oil drilling.

Delivery status:With heat treatment (normalized, annealed or high temperature tempered) or without heat treatment Goods, the delivery status should be specified in the contract

Heat treatment:
1. Normalizing: Heat the furnace to **0°C~**0°C, keep the thickest cross section per inch at this temperature for one hour, and cool in air.
2. Heat to austenitizing at a temperature of **0℃~**5℃, and keep the thickest cross section per inch for one hour at this temperature
3. Normalizing or oil quenching, and cooling to a maximum temperature of **1°C
4. Temper at a temperature that achieves the following mechanical properties. The thickest cross-section per inch is held for one hour at the tempering temperature, and the tempering temperature range is **0 ° C ~ **0 ° C
5. For each heat treatment process, a heat treatment chart must be drawn.
6. The mechanical property test shall be carried out in accordance with the stipulations of ASTM. A***0. The sample material used for the test shall be cut from the test bar of the same furnace steel. The casting or forging represented by the sample and the test bar shall be in the same furnace. The test bar shall be heat treated in the same furnace together with the charge.
7. The mechanical properties should meet the following requirements: (Tested with a test bar, sampling according to APT 6A, **0K standard) - Tensile strength minimum lb/inch (**2) Yield strength minimum lb/inch **0.**0 (**8) 2 inches The minimum value of elongation is *5% and the minimum value of section shrinkage rate is %*0. Brinell hardness HB**5 ~ take, the casting or forging represented by the sample and the test bar must be in the same furnace, and the test bar should be heat treated in the same furnace together with the charge.
8. The mechanical properties should meet the following requirements: (tested with test bars, sampling according to APT 6A, **0K standard) - minimum tensile strength lbs/inch (**2) minimum yield strength lbs/inch (**8) 2 inches Minimum elongation %*5 Minimum shrinkage of section %*0 Brinell hardness HB**5~**2
9. Marking: Each part shall be printed with heat treatment marks and hardness with low stress steel stamp.
