What is SA182?

ASTM A182 F6a is a forged martensitic stainless steel with 13 wt. % chromium. Martensitic stainless steels can be high-carbon or low-carbon steel alloys.

What is ASTM A182 F304?

ASTM A182 F304 is a forging material specification for 304 grade stainless steel and is used for manufacturing bare forgings or forged and machined products for applications involving high temperature service.

What is F22 material?

Grade F22 is a low alloy steel containing nominally 2.25% Chromium. The alloy is widely used in the oil patch wellhead applications for connectors, hangers and block valves. Hardness levels up to 22 HRC are approved to NACE MR0175. The grade is often used as the base metal for clad components.

What is a351 CF8?

Stainless Steel SA-351 CF8 is the cast equivalent of Type 304 Stainless Steel, part of a range of austenitic chromium-nickel alloys that provide good strength and ductility. They are also known as 18/8 stainless due to their chemical composition which includes approximately 18% chromium and 8% nickel by weight.

What is A516 Grade 70 steel?

ASTM A516 Grade 70 Plate is also called out as ASME SA516-70. This steel plate grade is a medium carbon alloy that also contains amounts of manganese, phosphorus, sulfur, and silicon. A516 is primarily used for service in welded pressure vessels where improved notch toughness is required.

What is the difference between ASTM and ASME SA?

ASME standards are generally based on the appropriate ASTM standards, but the standard numbers are preceded with the letters ‘SA’, rather than just the ‘A’ of the ASTM standards. The difference between an A and a SA designation has to do with ASME Boiler and Pressure Vessel Code endorsement of a material.

What is A182 F9?

ASTM A182 F9 is a forging material specification for F9 grade alloy steel and is used for manufacturing bare forgings or forged and machined products for applications involving high temperature service.

What kind of pipe does a 182 / SA 182 use?

A 182 / SA 182. Standard Specification for Forged or Rolled Alloy-Steel Pipe Flanges, Forged Fittings, and Valves and Parts for High-Temperature Service. Overview.

Which is better ASME f316l or ASME SA 182?

In comparison to chromium-nickel based austenitic stainless steel grades, the molybdenum bearing ASME SA182 F316L Pipe Flange offers higher creep, stress to rupture as well as tensile strength at high temperatures.

What’s the weight of a 182 / SA Bar?

A 182 / SA 182. 1.2 For bars and products machined directly from bar, refer to Specifications A 479/A 479M and A 739, for the similar grades available in those specifications. Products made to this specification are limited to a maximum weight of 10 000 lb [4250 kg]. For larger products and products for other applications,…

Why are ASTM A182 f316l stainless steel flanges low in carbon?

The significant reduction in the content of carbon in the ASTM A182 F316L Flanges is what yields high compatibility with welding and eliminates intergranular corrosion caused by sensitization of grain boundary precipitates. However, the low content of carbon also indicates that alloy grade 316L has a low structural strength.
