As an acclaimed undertaking of the business, Unisteel & engineering as a manufacturer & exporter of an super high grade quality of Stainless Steel 904L Buttweld Fittings, also known as UNS N08904 to our domestic and international customers.
904L Stainless Steel 90 deg. Elbow Buttweld Fittings consolidates molybdenum and copper with iron for immensely expanded imperviousness to diminishing acids like sulphuric corrosive.
Our offered SS 904L U bends and 180 Deg. Bends is applicable in aircraft, furnace and chemical process components, honeycombs and gas turbine combustion section components. Alloy 904L is an additional member of the Ni – Mo – family of alloys with a special chemistry designed.
Type 17-4 PH Stainless steel is the most widely used of all of the precipitation- hardening stainless steels. Its
valuable combination of properties gives designers opportunities to add reliability to their products while
simplifying fabrication and offen reducing costs. Type 17-4 PH is a martensitic precipitation-hardening stainless
steel that provides an outstanding combination of high strength, good corrosion resistance, and good mechanical
properties at temperatures up to 600o F (316oC). Its unique combination of properties make this alloy an effective
solution to many design and production problems.

SS 17-4 PH
Resistance to Corrosion :
Type 17-4 PH stainless steel has excellent resistance. It withstand corrosive attack better than any of the
standard hardenable stainless steels and is comparable to type 304 in most media. this has been tested in a
wide variety of corrosive conditions in the petrochemical, petroleum, paper, dairy and food processing
industries, and in applications such as boat shafting.

Type 17- 4 PH stainless steel has excellent mechanical properties. For applications requiring high strength and
hardness as well as corrosion resistance, Type 17- 4 PH stainless is an outstanding choice, and it is more cost
effective than many high nickel non-ferrous alloys.
General Characteristics :
• Excellent resistance to corrosion
• Provide toughness in both base metals and welds.
• Well suited to applications that require ease of fabrication and then the addition of strength / hardness for improved reliability
• Aerospace applications
• Chemical processing equipment
• Oil and Petroleum refining equipment
• Food processing equipment
• General metalworking
