Since these are heavy duty tension nuts, they are used in high vibration and high stress applications such as aircraft engine parts and automotive engine parts. ASTM A194 Class 2h material consists of all classes of carbon, manganese, phosphorus, sulfur and silicon.

These are flanges with creep strength and high resistance; therefore, steel threaded flanges help them work in the petrochemical industry.

825 is an austenitic Ni – Fe – Cr – Mo – Cu nickel based alloy developed to resist corrosion in very aggressive media.Alloy 825, also known as Incoloy 825, is a nickel-iron-chromium alloy with molybdenum and copper added.

These ASTM A182 Alloy Steel F12 Flanges are manufactured from high quality raw materials, so the manufactured products are of high quality. Additionally, these ASTM A182 Alloy Steel F12 Flanges are manufactured with the necessary standards, codes and guidelines in mind, resulting in a high quality product.

In addition to good corrosion resistance, the addition of chromium and molybdenum to the alloy enhances its ductility.

L7 threaded studs and short head bolts are readily available in the market.

The alloy steel of ASTM A182 F11 flanges is called chrome-moly flanges. These are flanges that contain chromium and molybdenum, these are the ingredients that make them resistant to corrosion, which also adds to its toughness.

Nuts with a nominal size over 1 inch shall be a UNC Series Class 2B fit or an 8 UN Series Class 2B fit. High strength ASTM A194 grade 2H nuts are common in the market and are often replaced by ASTM A563 grade DH nuts due to the limited availability of DH nuts in certain diameters and finishes.

ASTM A193 Grade B8M Grade 1 Fasteners are similar to Grade B8 but are made of AISI 316 stainless steel instead of AISI 304 stainless steel. Type 316 stainless steel has better corrosion resistance than type 304 stainless steel due to the addition of molybdenum.

The Welding neck flanges are available across various materials. These materials will have to be as per the Standards set. The materials also should be as per the quality specified by the ASTM or ASME standards.

Alloy 20 (Alloy 20) is an iron-based austenitic alloy developed to resist sulfuric acid corrosion. It has excellent resistance to sulfuric acid corrosion; it has strong resistance to phosphoric acid, nitric acid and chloride environments, chloride stress corrosion, pitting corrosion and crack corrosion. Therefore, alloy 20 has the name of anti-corrosion alloy; it has a wide range of applications: such as: chemical, food, medicine, power production and plastics industries will use it. For resistance to pitting corrosion and chloride corrosion, stress corrosion cracking problems, etc., alloy 20 is often used.

B7 and B7M shall be heat treated by quenching in a liquid medium and tempering. For B7M fasteners, the final heat treatment, which may be the tempering operation if conducted at 1150 ¡ãF [620 ¡ãC] minimum, shall be done after all machining and forming operations, including thread rolling and any type of cutting.

The ASTM A320 specification, originally approved in 1948, covers alloy steel and stainless steel bolting materials for low temperature service.

The high chromium content gives these alloy steel socket weld flanges very good resistance to moisture erosion, which also contributes to their high temperature strength and resistance to scaling at high temperatures.

In order to improve the thermal efficiency of the reheat steam pipeline of the power plant, the reheat temperature can be designed to be 621¡ãC, that is, the supercritical temperature. The United States first developed ASTM A335 P92 alloy steel in the late 1980s to meet the heat resistance requirements of this high temperature power plant. Alloy Steel P92 is an improved version of ASTM A335 P91 alloy with deliberate additions of tungsten, vanadium, niobium, reduced molybdenum content to fine-tune the ferrite/austenite ratio, and carefully controlled boron and nitrogen content.

These pipe fittings of B366 N06601 B366 N08825 B366 N10276 B366 N08020 materials, are used in the chemical industry, as well as in pressure vessels.

HASTELLOY C-276 alloy is available in the form of plates, sheets, strips, billets, bars,
wires, pipes, tubes, and covered electrodes.

A182 F9 flanges also contain carbon, manganese, silicon, phosphorus, sulfur, molybdenum and 8% chromium in their composition. This combination provides the joint with a minimum tensile strength of 585MPa and a minimum yield strength of 380MPa.

Chromium-molybdenum alloy steel has strong crack resistance under high temperature and high pressure. Chromium molybdenum is also resistant to hydrogen attack and hot sulfide corrosion cracking.

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.

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%.
