Low alloy steel ASTM A182 F11 flanges typically have a total alloy content of 1.5% – 5%. Its common alloying elements are manganese, chromium, silicon, nickel, molybdenum and vanadium. It may contain up to four or five different quantities of these alloys. At the same time, the increased strength of the alloy steel F11 flange may require higher forming pressures. Annealing of SA 182 Gr F11 steel flanges is accomplished by water quenching by thorough immersion at 1725¡ãF – 1850¡ãF (941¡ãC – 1010¡ãC) and can only be hardened by cold work.

800H can resist corrosion of many corrosive media. Its high nickel content makes it resistant to stress corrosion cracking in aqueous corrosion conditions. The high chromium content provides better resistance to pitting and crevice corrosion cracking. The alloy has good corrosion resistance to nitric acid and organic acids, but limited corrosion resistance in sulfuric acid and hydrochloric acid. Good corrosion resistance in oxidizing and non-oxidizing salts, in addition to the potential for pitting corrosion in halides. It also has good corrosion resistance in water, steam and mixtures of steam, air and carbon dioxide.

Alloy 32750 is a super duplex stainless steel supplied in hot worked and solution annealed conditions. As a super duplex stainless steel, it combines the desirable aspects of austenitic and ferritic steels. Higher chromium, molybdenum and nitrogen content results in a Pitting Resistance Equivalent Number (PREN) > 40, providing superior pitting and crevice corrosion capabilities to austenitic and duplex stainless steels in virtually all corrosive media, and critical pitting temperature over 50¡ãC.

Chromium molybdenum has a better strength-to-weight ratio than steel, which enables designers to use thinner walled tubing or smaller diameter tubing to reduce overall weight.

A182 F91 Wrought alloy steel tubes, flanges, wrought fittings and valves and other components for high temperature use.

Chromium molybdenum has a better strength-to-weight ratio than steel, which enables designers to use thinner walled tubing or smaller diameter tubing to reduce overall weight.

Our alloy steel blind flanges are mainly caused by environmental factors such as wind exposure, man-made pollution and high temperature, and are more serious near the ocean, which is the main cause of seawater pollution.

Grade P11 is known as chrome molybdenum alloy steel. Compared to carbon steel, the properties of this alloy steel are much higher. Typically, alloy steels such as ASTM A335 P11 pipe tend to have much higher element percentages than conventional steels. So take their efficiency to the next level. The alloy composition of the P11 grade consists of chromium and molybdenum, with a chromium percentage of approximately 1.25. The content of molybdenum in the alloy steel P11 seamless pipe is about 0.5%.

Alloy steel is steel that is alloyed with a variety of elements in total amounts between 1.0% and 50% by weight to improve its mechanical properties. Alloy steels are broken down into two groups: low alloy steels and high alloy steels. The difference between the two is disputed. Smith and Hashemi define the difference at 4.0%, while Degarmo, et al., define it at 8.0%.[1][2] Most commonly, the phrase “alloy steel” refers to low-alloy steels.
