Products Description
Welded flange connection is to fix two pipes, pipe fittings or equipment on a weld. A flange pad is added between the two welds and fastened together with bolts to complete the connection. Welding is an important connection method in high-pressure pipeline construction. Welded flange connections are easy to use and can withstand greater pressure. Welding flanges are widely used in petroleum, chemical industry, natural gas, power stations, metallurgical pipelines and other fields.

1.4460 stainless steel is duplex steel being a combination of austenitic and ferritic types. It can resist pitting as well as corrosion cracking under stress. This type of steel is better to use in forged valve pumps and their components.1.4460 stainless steel is also frequently used for centrifugal machines. This type of steel forges better at temperatures around 1250/1050C or 2280/1900F. The parts need to be air-cooled once they are forged. Duplex steel of such grade is very difficult to weld, and hence its machinability is very low.
1.4541 stainless steel ,also known as UNS S32100, has amazing resistance to any intergranular corrosion post-exposure to 800-1500°F temperatures. This titanium stabilized alloy can easily resist oxidation along with a higher creep & stress rupture property when compared to the alloys 304 or 304L.

FAQ
Q:How is stainless steel 304 different from 321?
A:Stainless steel 304 is a low-carbon based alloy that is heat resistance due to the presence of chromium and nickel. On the other hand, Stainless Steel 321 houses chromium-nickel alloy with titanium combination.
Q:What is the temperature for the full martensite transformation of SS 329?
A:The temperature for a full martensite transformation for Type 329 SS is 1038C (1090F) for 30 minutes and then cool it down below 16C (60F).
Q:How to forge SS329?
A:Soak SS 329 at 1177C (2150F) for 60 minutes. Don't work it below 1010C (1850F). Post-work treatment is mandatory before the steel hardens.
