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.

B8M Grade 1 fasteners require carbide solution treatment, while Grade 2 fasteners require additional strain hardening operations to increase strength and reduce susceptibility to wear.

Alloy steel F12 bar offers some great properties such as strong construction, all-around durability, a wide range of sizes to choose from, and more.

Chromium Molybdenum Alloy Steel or Chromium Molybdenum, CrMo is an alloy steel used for high temperature and high pressure service.

The P2 and P12 steel pipes of A335 should be made by the coarse grain melting method. Steel should meet chemical composition, tensile properties and hardness requirements.

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.

The material contains carbon, manganese, phosphorus, sulfur, silicon, 8% chromium and molybdenum in a mixture. SA 335 grade P5 alloy steel pipe has similar strength to most austenitic stainless steel grades, with a minimum yield strength of 205MPa and a minimum tensile strength of 415MPa.

As one of the leading Alloy Steel Flanges Manufacturers in China we supply all different types of flanges in all material grades. Please contact us for your alloy steel flange needs.

A182 threaded flanges are primarily used for utility services such as air and water. It is similar to a Slip-On flange, but the holes are threaded.

Regardless of its cost-effective solution, F11-grade rebar is a way to meet the corrosion resistance and mechanical performance requirements set by various industries.

The ASTM A333 standard covers seamless walled and welded carbon and alloy steel pipes for cryogenic use. ASTM A333 Alloy Pipe shall be manufactured in a seamless or welded process with no filler metal added during the welding operation.

Forming operations such as bending and flanging, as well as fusion welding, are well suited for ASTM A335 p11 alloy steel pipe. The specified tests for alloy steel seamless pipes include flattening test, bending test, hardness test and longitudinal or transverse tensile test.

The provided Alloy Steel F21 Flange are efficiently manufactured using the superior quality nickel alloy with the aid of pioneering methodology.

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.

Chromium Molybdenum Alloy Steel or Chromium Molybdenum, CrMo is an alloy steel used for high temperature and high pressure service. Chromium molybdenum is used in power generation and petrochemical industries for its tensile strength, corrosion resistance and high temperature strength.

Alloy Steel Flanges are made in different steel alloys. The flanges vary in dimensions and types. There are ? inches through 48 inches of nominal diameter sizes of flanges.

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.

The Alloy Steel F12 Flanges are also very strong due to the annealing of them. Grade F12 Flanges can be supplied in either normalized or quenched and tempered conditions. Alloy Steel F12 Weld Neck Flanges is appropriate to various applications where its different remarkable characteristics are sought-after but a brushed/polished finish is not necessary.

ASTM A193 Grade B7 specification covers requirements for high tensile alloy steel bolting material for use in high temperature or high-pressure service and other special purpose applications.

The flanges can be threaded, ring type joint, lap joint, weld neck or socket welded.

ASME SA 335 grade P22 alloy steel pipe can withstand high pressure and high temperature. Therefore, ASTM A335 P22 pipe is used in applications that need to operate at high pressure and high temperature.

A182-F11 is an American standard pearlitic structure heat-resistant steel forgings, the execution standard: ASTM-A182/A182M-2017.

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.

When the carbon content of the a333 gr 6 welded pipe chemistry is lower, the chance of cracking in the welded area is also lower. However, some manufacturers prefer seamless pipes over welded pipes. The reason behind this is that the performance of the a333 gr 6 seamless tube is almost 20% higher than the welded one in high pressure environments.

Users of SA182 Chrome Moly Gr.f9 forged bar do not rely solely on external coatings or finishes.

ASTM A182 Gr F1 Blind Flange is a solid disc used to block a pipe or create a stop. It is similar to an ordinary flange, with mounting holes around it, and the sealing ring is machined into a mating surface.

The connection between two pipes can be directly welded together, but it is difficult to connect together without welding. When the connection part have problems, it will be hard to repair. The same problem also happened between pipe and valve connection.

The achievable mechanical properties depend on added elements such as nickel, chromium, molybdenum and vanadium. The following are a series of improved properties of alloy steel (compared to carbon steel): strength, hardness, toughness, wear resistance, corrosion resistance, hardenability and hot hardness. To achieve some of these improved properties, the metal may require heat treatment.

ASTM A182 Grade F5 Flanges are suitable for connecting pipes of small bore size and without the requirement of welding. ASTM A182 GR F5 Flange belongs to the ASTM A182 specification. The dimensions of the flanges vary according to the ANSI, ASME and DIN standards. The flange sizes range from ? inches to 36 inches in nominal bore sizes. Navstar Steel is a leading supplier and manufacturer of these flanges in various sizes and types.

ASTM 182 is used for pressure systems, including flanges, fittings, and similar parts that conform to specified dimensions or dimensional standards such as ASME codes.
