Grade 22 of the ASTM A182 alloy steel is a low-alloy steel that contains 2.25% chromium. Often used as base metal for clad components, the F22 is also used in the oil patch wellhead applications for products such as hangers, connectors, and block valves, among others. When supplied to ASTM A182 in the normalized and tempered condition, the 0.2% proof stress minimum is 30 KSU.

This type of steel is primarily made in Dubai, U.A.E.; Houston, Texas; Singapore; Sheffield, England; and Edmonton, Canada. ASTM A182 is the standard specification for rolled or forged alloy, as well as stainless-steel pipe flanges, forged fittings, and parts and valves used for high-temperature service.

Types of Products Available

Some of the products that a good alloy steel manufacture company might make out of this type of steel include piping components in pressure systems, and they are parts that are similar to certain specified dimensions or dimensional standards. Some grades of low-alloy steels and martensitic, ferritic, austenitic, and ferritic-austenitic stainless steels may be included if you order the F22 grade steel products.

The F22 grade is a low-alloy steel, and it is very deep-hardening and heat-treatable. Furthermore, it normally contains about 12% carbon, 2.25% chromium, and 1.0% molybdenum, which are the three main hardening elements. The steel is used in wellhead applications and is an upgrade over the AISI 4130 type of steel.
