Stainless steel is a versatile alloy is considered to be amongst the most widely used metals across the world.Stainless Steel A403 WP304 contains higher chromium and low carbon content.

This is used in fabrication of tubes, boilers and super heaters. On many other applications, this is used and is available in various other sizes and shapes.

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.

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.

Inconel600 is suitable for welding with the same material or other metals by any traditional welding process, such as tungsten electrode inert gas welding, plasma arc welding, manual sub-arc welding, metal inert gas shielded welding, molten arc inert gas shielded welding, and pulsed arc welding. Welding is the preferred solution. When using manual arc welding, it is recommended to use a shielding gas mixed with various components (Ar+He+H2+CO2).
Welding of Incoloy 825 must be carried out in the annealed condition and cleaned with a stainless steel wire brush to remove stains, dust and various markings. When welding the root of the weld, extreme care must be taken (Argon 99.99) to obtain the best quality of the root weld so that the weld does not produce oxides after the root has been welded. Color from the weld heat-affected zone should be removed with a stainless steel brush while the weld area is not cool.

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

Flange connection has good strength and sealing, simple structure and low cost. It can be repeatedly disassembled.

It helps improve fatigue resistance. Many industries, including paper and pulp, chemical reprocessing, water pipelines, nuclear power plants, heat exchangers and others, use ASME sa182 f12 projects in a variety of applications. Our Premium Alloy Steel F12 Flanges are corrosion free, edge perfect, efficient, lightweight, frictionless work, easy to install, highly conductive and of great quality.

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.

Pipe Fittings are usually socket welded or threaded. The high chromium content gives these forgings fittings very good resistance to moisture erosion

ASTM A193 B7 bolts are manufactured to meet numerous specifications and material design properties. More specifically, B7 alloy steel is a high temperature grade of A-193. B7 steel is also a chromium molybdenum steel with a minimum tensile strength of 125ksi.

A/SA387 GR 9CLASS 2 Weldable carbon steel plate for high temperature pressure vessels and boilers. The material benefits from added chromium and molybdenum, which give the steel better corrosion and heat resistance. A/SA387 Grade 9 is intended for use by manufacturers serving the oil, gas and petrochemical industries.

It is almost the same as AISI 4130 chrome-molybdenum alloy steel, but with a slightly higher carbon content. Compared to AISI/ASTM 4130 alloy steel, AISI 4140 steel has a higher carbon content, which provides higher strength and heat treating capability, but also has limited weldability.

ASTM A182 Alloy Steel Forged Flanges are manufactured according to the ASTM A182 specification, which covers high pressure and high temperature service flanges covered by ASME B16.5, B16.47 and B16.48 standards.

Alloy steel flanges have corrosion oxidation stress corrosion cracking and crevice corrosion resistance.

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.

ASTM specifications recommend a minimum Charpy impact value for ASTM A320 L7 Stud Bolts to be 20-ft-lbf @ -150F. The Charpy impact test determines the total amount of energy that is absorbed by a material during fracture, thereby indicating the material¡¯s notch toughness.

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.

This is useful for selecting bolts with different strength levels for different high pressure and high temperature applications. ASTM A193 grade b7 hex bolts and other types have a minimum tensile strength of up to 125ksi.
