a105 is forged carbon steel fittings and are used in ambient temperature or low temperature service whereas, a234 is wrought carbon steel/low alloy steel fitting used in moderate or elevated temperatures.
En8 is low carbon steel and it can be toughned. En24 is medium carbon steel and it is generally called forged steel.
Pre-64 Winchesters had many forged and hand-fitted parts while those made later are machine-stamped. If you haven't studied metal working enough to recognize the difference, 1964 production bagan with serial number 2586001.

Pipe ratings are the operating pressures that a pipe can be constantly operated at. There are a few classes of Plumbing pressures. Schedule 40 black iron is 150 psi class, meaning that the "operating pressures" are 150 psi. The 300 psi class is the class for most schedule 80 black iron (no seam [welded]). Each class has it's own fittings at the same ratings. The fittings wont be listed as a schedule just a class or a psi rating. Other ratings can exceed 3000 psi for hydraulic actuated machinery applications. Again, these classes have there own set of 3000 class fittings which are usually forged instead of cast. The ratings include a safety factor of 2 and an extra surge allowance of 100 psi for very short term operation. The rating only goes to the yield strength of the pipe not the failure strength, know the difference. So the burst pressures someone else gave as the pressure rating (2700 +psi) is wrong unless the person asking this question was trying to make a "pipe bomb."
Forged fittings are pressed into shape while the metal is hot and generally have higher pressure ratings. Cast fittings are formed by pouring molten metal into a form and general have lower pressure capacity when compared to forged fittings.

Wrought Iron
Forged fittings use hubs or ends for fillet welding to pipe. They are used for smaller pipes or one that will have high pressures passing through.
Forged iron is generally stronger than wrought iron because the forging process helps align the grain structure, creating a more uniform and stronger material. Wrought iron is more malleable and ductile, making it easier to shape but not as strong as forged iron.

Western Steel Agency is an ANSI Forged Fittings Manufacturers in India. Forged fittings are essential components in various industries, providing reliable connections in piping systems. The use, the surrounding environment, and financial constraints are some of the elements that influence the choice of materials for forged fittings. Forge fittings are frequently made of carbon steel, stainless steel, and alloy steel. Forged fittings made of carbon steel are reasonably priced and ideal for a variety of uses, however they might corrode in some conditions. For use in severe or corrosive environments, stainless steel forged fittings provide exceptional corrosion resistance, making them perfect for use in sectors such as chemical processing and maritime applications. Power plants, petrochemical companies, oil and gas pipelines, and other high-pressure and high-temperature applications can benefit from the exceptional strength and longevity of alloy steel forged fittings.
ASTM A105 is a Carbon Steel material spec used in forged fittings, such as 2000# or higher socket weld or threaded fittings, forged flanges, etc.. ASTM A197 is a Malleable iron material spec used in 150# socket weld or threaded fittings.

Weldolet is a trademarked name by Bonney Forge for internally reinforced forged branch outlet fittings. Pipet is a trademarked name by WFI for internally reinforced forged branch outlet fittings. Both comply with MSS SP-97 Internally Reinforced Forged Branch Outlet Fittings - Socket Welding, Threaded and Buttwelding Ends. Referenced in ASME B31.3-2020 304.3.1 a) (1). They are the same
