Nickel Alloy 400 and Monel 400, also known as UNS N04400, is a ductile nickel-copper-based alloy consisting primarily of two-thirds nickel and one-third copper. Nickel Alloy 400 is known for its resistance to a variety of corrosive conditions, including alkalis (or acids), salt water, hydrofluoric acid, and sulfuric acid. Since Monel 400 or Alloy 400 is a cold worked metal, this alloy has high hardness, stiffness and strength. By cold working ASTM B164 UNS N04400 bar stock, the alloy is subjected to higher levels of mechanical stress, which in turn causes changes in the alloy’s microstructure.

The difference between 304 and 304L stainless steel is that 304L has a .03 max carbon and is good for welding whereas 304 has a mid range level of carbon.

Grade 304L is widely used in the manufacturing industry and all standard welding techniques can be used for 304L plate and 304L pipe. The “L” in 304L stands for “low carbon content” and indicates a maximum carbon content of 0.035%. The “H” in 304H stands for “High Carbon Content”, which means that the carbon content is not less than 0.04% and not more than 0.10%.

Duplex stainless steels are considered resistant to stress corrosion cracking because they are not as resistant to this form of corrosion as ferritic stainless steels.

Monel 400 is widely used in Brine heaters, sea water scrubbers in tanker inert gas systems.

Duplex 2205 Tube may at times exhibit magnetic behavior because the microstructure of its alloy contains about 50% ferrite.

C22 nickel alloy fasteners offer better overall corrosion resistance than its sister alloy Hastelloy C-276, and more specifically, it offers better protection when used in certain saturated wet chlorine environments. Additionally, its high chromium content provides C22 fasteners with better resistance to oxidative media than C276. This makes it excellent resistance to chloride-induced pitting, although in most cases C-276 fasteners are a more cost-effective option due to their availability, especially in sizes smaller than 1/ 2″ case.

S31803 is the Unified Numbering System (UNS) designation for the original duplex stainless steel. The UNS system was created by multiple trade groups in the 1970s to reduce confusion when the same alloy was called different things, and vice versa. Each metal is represented by a letter followed by five numbers, where the letter represents the metal series, i.e. S for stainless steel.

For paper mill applications requiring lower alloy grades that do not have sufficient corrosion resistance. Based on a 22% chromium content, they have a combined austenitic:ferritic microstructure that provides greater strength, corrosion resistance and cost-effectiveness.

The UNS S31803 (ASTM F51) specification has been largely superseded by UNS S32205 (1.4462, ASTM F60). This reflects their desire to maximize the alloy’s corrosion properties, thanks to the development of the AOD steelmaking process, which allows for tighter control of composition. In addition, it allows to influence the nitrogen addition level rather than just being present as a background element. Therefore, the highest performing duplex grades seek to maximize the content of chromium (Cr), molybdenum (Mo) and nitrogen (N).

Grade 304 stainless steel is the standard “18/8” stainless steel; it is the most versatile and widely used stainless steel available in a wider range of products, forms and finishes than any other.

The flange is second most used joining method after selding. Flanges are used when joints need dismantling. It provides flexibility for maintenance. Flange connects the pipe with various equipment and valves. Breakup flanges are added in the pipeline system if regular maintenance in required during plant operation.
A flanged joint is composed of three separate and independent although interrdlated components; the flanges, the gaskets, and the bolting; which are assembled by yet another influence, the fitter. Special controls are required in the selection and application of all there elements to attain a joint, which has acceptable leak tightness.
A flange is a protruded ridge, lip or rim, either external or internal, that serves to increase strength (as the flange of an iron beam such as an I-beam or a T-beam); for easy attachment/transfer of contact force with another object (as the flange on the end of a pipe, steam cylinder, etc., or on the lens mount of a camera); or for stabilizing and guiding the movements of a machine or its parts (as the inside flange of a rail car or tram wheel, which keep the wheels from running off the rails). The term “flange” is also used for a kind of tool used to form flanges.
