17-4 PH Stainless Steel (SAE Type 630 Stainless Steel), is a martensitic precipitation hardening stainless steel casting grade.
Typical uses for 17-4 stainless steel castings require high strength and moderate corrosion resistance. The required strength and toughness can be controlled by the temperature range during heat treatment. Best Stainless offers high quality standards including: UNS S17400, AMS 5643, ASTM A564 and ASTM A693 Grade 630.

heat treatment
This type of stainless steel casting can be further hardened by aging in a temperature range between 480-620 degrees Celsius. The combination of the alloy's exceptional properties allows it to increase product reliability while enabling easy and cost-effective fabrication. Type 17-4 PH stainless steel has applications in industries such as paper, petrochemical, aerospace and food processing. It is widely used in a variety of general metalworking applications.

Advantages of 17-4 PH Stainless Steel Castings
17-4 PH stainless steel castings withstand corrosion attack better than any standard hardenable stainless steel castings and are comparable to alloy 304 in most media.

Corrosion resistant in some chemical, petroleum, paper, dairy and food processing industries (equivalent to 304L grade).

Typical Applications of 17-4 PH Stainless Steel Castings
Oil and Gas Industry

First, oil is usually obtained at great depths below sea level. Such depths are associated with high pressure. The high strength of Type 17-4 PH stainless steel castings makes them ideal for piping systems of this depth.

Second, Type 17-4 PH stainless steel castings are resistant to offshore and offshore corrosion. Its resistance to aggressive media such as hydrogen sulfide gas, carbon dioxide, and low pH levels under oil exploration conditions makes it perfect for the oil and gas industry.

food processing equipment

If you work in the food and beverage industry, you should know that most of the equipment you use is made of stainless steel. Type 17-4 PH stainless steel castings are used in food and beverage processing and manufacturing equipment.

17-4 stainless steel castings are ideal for their good surface condition and high finish. The smooth surface and high chromium content make it resistant to corrosion and easy to clean, since hygiene is an integral element in food and beverage manufacturing.

Of course, 17-4PH stainless steel castings can also be used in other industries, such as pulp and paper industry, shipbuilding, etc.
