Characteristics of material 17 4 PH

Special properties of steel 17-4 PH material are its suitability for low temperatures, its suitability for use at temperatures up to approx. 315°C, its high strength and toughness, and the fact that it can be age-hardened. Strength can be increased by cold forming with subsequent aging.

Forging of AISI 174 PH

Forging of 17 4 stainless steel takes place in a temperature range from 1180°C to 950°C. Cooling to room temperature takes place in air.

Steel 17 4PH: Welding

Optimum welding conditions are required for welding. The condition of the base material must be taken into account, as copper is present in stable form. This does not promote hot cracking. To prevent stress cracking, the material must be subjected to solution annealing again within a very short time after welding, followed by aging.

Corrosion resistance of stainless steel 17 4PH

17-4 stainless steel is suitable for use in marine environments. This stainless steel has very good mechanical properties and corrosion resistance. Additional protection is required against crevice corrosion caused by standing seawater.

Machining of material 17-4 PH

17-4 PH material is machinable in the age-hardened and solution-annealed condition. Depending on the hardness, the machinability varies depending on the condition.

Important questions

What is 17-4 PH stainless steel standard?
The standard for 17-4 PH stainless steel is typically ASTM A693.

What is the ASTM equivalent of 17-4 PH?
The ASTM equivalent grade for 17 4PH is ASTM A564 Type 630.

How hard is 17-4 PH stainless steel?
The hardness of 17 4 stainless steel can vary depending on the heat treatment and aging process it undergoes. Typically, it can achieve a hardness range of approximately 35-45 HRC (Rockwell C scale) after heat treatment.

What phases are in 17 4 PH steel?
174 PH primarily consists of a martensitic phase (alpha prime) and a precipitation-hardening phase (delta or gamma prime) formed during aging heat treatments. These phases contribute to the material’s strength and hardness.

Is 17-4 PH stainless steel magnetic?
17 4 material is generally magnetic in all conditions due to its martensitic structure. However, its magnetic properties can be affected by factors such as heat treatment and aging processes.
