ASTM 15-5PH Stainless Steel Coils

Description of ASTM 17-7PH Stainless Steel Coils

ASTM 17-7PH Stainless Steel Coils are a precipitation-hardening stainless steel alloy that is designed to exhibit high strength and excellent corrosion resistance. This alloy is a martensitic stainless steel that contains 17% chromium, 7% nickel, and 1.5% aluminum. The aluminum content in this alloy promotes the formation of small, tightly packed, and uniformly dispersed particles of aluminum oxide during the heat-treatment process. These particles provide the alloy with its characteristic strength and toughness.

The heat-treatment process for ASTM 17-7PH Stainless Steel Coils involves a solution annealing step followed by a precipitation hardening step. The solution annealing step is carried out at a temperature of around 1950°F to dissolve any carbides that may have formed during the cold-rolling process. The coils are then rapidly cooled to prevent the formation of new carbides.

The precipitation hardening step involves heating the coils to a temperature of around 900°F for several hours. This causes the aluminum oxide particles to form, which in turn increases the strength and hardness of the alloy. The final properties of the alloy can be adjusted by varying the time and temperature of the precipitation hardening step.

ASTM 17-7PH Stainless Steel Coils are used in a variety of applications that require high strength and excellent corrosion resistance. These include aerospace components, springs, and medical instruments. The coils can be easily formed and welded, and they exhibit good fatigue resistance and dimensional stability.
