Standard: GB / T 1298-1986

T9A characteristics and scope of application:

T9A performance and T8 and T8A similar, T9A for the manufacture of high hardness, a certain toughness but not the impact of severe vibration tools, such as the center of the pistol, punch, punch, wood cutting tools and feed machine blade, Chisels and other tools.

T9A Chemical composition:

Carbon C: 0.85 to 0.94

Silicon Si: ≤0.35

Mn Mn: ≤0.40

Sulfur S: ≤0.020

Phosphorus P: ≤0.030

Chromium Cr: promised residual content ≤ 0.25, ≤ 0.10 (manufacturing lead bath quenching wire)

Nickel Ni: promised residual content ≤ 0.20, ≤ 0.12 (manufacturing lead bath quenching wire)

Copper Cu: promised residual content ≤ 0.30, ≤ 0.20 (manufacturing lead bath quenching wire)

Note: promise residual content Cr Ni Cu ≤ 0.40 (manufacturing lead bath quenching wire)

T9A mechanical properties:

Hardness: annealing, ≤ 192HB, indentation diameter ≥ 4.35mm; quenching, ≥ 62HRC

T9A heat treatment specifications and microstructure:

Heat treatment specifications: sample quenching 760 ~ 780 ℃, water cooling.

T9A Delivery status:

The steel is delivered in an annealed condition. The agreement between the two sides can also be non-annealed delivery.

If you do not consider other mechanical performance indicators, then consider the hardness, then the same heat treatment conditions, the higher the carbon content, the more carbide, the higher the hardness, therefore, compared to T9A hardness higher than 80 steel, 80 steel hardness higher than 70 steel.Carbon spring steel wire is a high-quality high-carbon steel wire, high strength and high toughness, but also can manufacture steel wire and manganese phosphate coating wire rope.

As the steel industry market price fluctuations, and the material, specifications and varieties of more unit price is not the same, the above parameters and prices for reference only, the specific price please e-mail or telephone consultation, the company will be subject to the actual offer.
