Products Description
ASTM A564 Alloy 17-4 PH AISI 630 is a precipitation hardening martensitic stainless steel with Cu additions. The grade combines high strength, hardness (up to 300°C / 572°F) and corrosion resistance, combining high strength and post heat treatment hardness with excellent corrosion resistance that, in tests, proved superior to standard grades such as 420, 431 and 410. In fact, the corrosion resistance of 17-4PH is comparable with that of Grade 304.

Characteristics of 17-4ph stainess steel:
● 17-4PH stainless steel delivery status: generally delivered in heat treatment status, and the type of heat treatment is indicated in the contract; If not specified, the goods shall be delivered without heat treatment.
Note: ① Unless otherwise specified, the single value is the highest value; ② When used in some pipe making processes, the nickel content of some types of austenitic stainless steel must be slightly higher than the values shown in the table; ③ At will; ④ The maximum TA content is 0.10%; ⑤ The maximum content is 0.75%; ⑥ The maximum content is 0.70%
17-4PH stainless steel alloy is precipitation, hardening, martensitic stainless steel.
17-4PH stainless steel alloy is a precipitation, hardening, martensitic stainless steel composed of copper, niobium/columbium.
This grade has high strength, hardness (up to 300 ℃/572 ℉) and corrosion resistance.
After heat treatment, the mechanical properties of the product are more perfect and can reach the compressive strength of 1100-1300 mpa (160-190 ksi).
This grade cannot be used at temperatures higher than 300 ℃ (572 ℉) or very low. It has good corrosion resistance to the atmosphere and diluted acid or salt. Its corrosion resistance is the same as 304 and 430.

Forging of ASTM T4 Tool Steel Materials
Forging of T4 steel can be carried out from 850 to 1120°C (1775 to 2100°F).
Preheat T4 steel material uniformly and slowly to 860-880°C.
Increase the forging temperature up to 1050-1120°C.
T4 hss tool steel should be cooled very slowly after forging.
AISI/ASTM T4 Tool Steel Heat Treatment and Properties
Hardening:
Harden T4 high speed tool steel from a temperature of 1260-1290oC followed by oil, air quenching or warm bath at 550oC. Hardness after quenching is 63-66 HRC.
Annealing:
T4 steel should be annealed after hot working. Increase the temperature of T4 high speed steel to 860°C(Max220°C per hour). Hold at the temperature and then cool slowly with the furnace. The annealed hardness achieved should be below HB255.
Tempering:
Tempering temperature: 2x 560-580oC. Hardness after tempering is 64-65 HRC.
